Wind Energy Success in Scotland

Often lauded as one of the most economic ways to gather energy, wind energy is set for a further boost after the grand unveiling of the world’s largest offshore wind turbine in Scotland.

As the fossil fuel resources appearing to be rapidly dwindling now and in the coming years, alternative forms of energy are coming to the forefront. Along with solar, wind energy could be the most viable solution for the future.

This has been backed up by the production of a gigantic turbine being optioned for operational usage later in the year by the Korean firm Samsung Heavy Industries who have invested a hefty £70 million into the project.

Not one to do things by halves, the company are due to break the record for the world’s large turbine with information released stating that the construction will measure in at an astonishing 196 metres above the sea at its blade tips.

All of this is pointing towards a positive future for the sector as well as Scotland as a whole. Up to 500 jobs are set to be created with power being sourced to as many as 4800 homes. Considering the toils of the nation since the worldwide financial slump hit, this could very well be the first big step on the road to recovery.

This was echoed by Maggie McGinlay of Scottish Enterprise who said, “"The development of the SHI turbine in Fife is testament to Scotland's growing reputation as a global centre of expertise for the next generation of offshore wind energy technologies.
"This, along with planned investment from other key players such as Areva and Gamesa, is helping to create a potential manufacturing hub on the east coast, which would lead to significant opportunities for our supply chain companies.”
The ground-breaking scheme has been met with plenty of positive reactions with particular regards to the First Minister Alex Salmond who has levied that Scotland runs completely by renewable energy by 2020.

With that being quite the possibility depending on the success of this initiative, there could be a bright future for Scotland and wind energy itself.

LEDs and Colour Rendering

LED strip lights
LED strip lights are an increasingly popular source of illumination for home and commercial use.

LED strip lights are one of the most popular LED products because of their varied lighting applications and ease of installation but LEDs are being recognised as superior lighting technology.  They are increasingly preferred over fluorescent and incandescent bulbs.  One of the main reasons for this is their high performance in CRI.  CRI is the colour rendering index.  This is a quantitative measure of the ability of a light source to reproduce the colours of various objects accurately compared to the results of natural light.  This is not to be confused with the apparent colour of said light source.  LEDs normally have 80+CRI with some claiming their LEDs achieve 98.  The highest CRI is 100.  In colour critical applications high CRI is most sought after, e.g. in photography.

There is a focus in the LED technology industry to balance CRI and luminous efficiency.  As technology in this filed continues to rapidly improve, LED strip lights, LED based retrofit lamps and all other manner of LED lighting is enjoying increasing success against its lighting competitors.

Phosphor use on LED lighting is also continuing to improve and allows more subtle light variation.  This aids the best results when we want LEDs with high CRI but low CCT.  This is the state most desirable for residential lighting.  CCT is correlated colour temperature.

LEDs are already ideal for office lighting, where clear, practical light is required for performing tasks.  In residential lighting aesthetics are more important.  It will be LEDs ability to work and deliver the best results in these different applications that will bring them to be widely used in most lighting in the future and they are well on their way.

Phosphor has been integral in the creation of warmer or cooler light effects in LEDs for residential use.  Phosphor coats the LEDs which appear as blue light and some of the blue is absorbed by the phosphor. This causes the phosphor to have a higher energy level.  Yellow or warmer light is achieved if all the blue light is absorbed by the phosphor. Absorbing only some of the blue light results in white light.

This technology is how LEDs, including the popular and seemingly simple LED strip lights, achieve their ability to produce such a great range of lighting effects.  Understanding this technology shows why LEDs are becoming a popular choice of lighting in all applications.

Cable Harnessing and the 50 Year old Computer

The past 50 years have seen plenty of changes in the technology industry with an amazing progression in computing. When once your computer would be the size of a room, projections say that handheld tablets will be the norm, even overtaking laptops.

One such computer who was around for the start of it all was Flossie: a giant machine that’s looking like making quite the comeback. As an ICT 1301 model, the main task was to produce test results for students at the University of London and measuring at 5 tonnes, Flossie could not be more of a far cry from modern day machines.

Flossie would have benefitted from the use of cable harnessing due to the significant amount of maintenance that had to go into keeping her ticking over. Fascinatingly, due to the bulky size of the model, the ICT 1301 found stardom after appearing in Doctor Who and James Bond.

The machine was later discarded and studied by students before finding its way to a farm owner who kindly donated the gigantic treasure.

Plans are now in place to fix Flossie’s mechanisms that were sadly damaged during transit by 2016. The idea is to house the enormous computer in The National Museum of Computing – a team dedicated to preserving historic parts of technology. Kevin Murrel, a trustee with the group said, "One of the problems with computers as museum artefacts is that when they are switched off they are fairly boring - it's fairly difficult to learn anything from them," explained Mr Murrell.
"So ideally we want it switched on, and once we've restored it we will be able to run the original software.”
An intriguing and passionate initiative, this news says a lot about the evolution of computers and how it has grown from humble beginnings to what it is now.

The Success of Solar Energy

The Swedish furniture firm Ikea have recently announced that they will be introducing solar panel
packages for the commercial market with solar cables being utilised with them also. This indicates that the solar energy business is becoming a more viable option for those looking for renewable energy.

Previously, you would have had to go through an industry specialist to achieve solar panelling for your household. Now though, it appears as if solar energy is becoming what is considered the norm. What used to be an odd commodity is now found on many house roofs. How has this once elite way of producing energy achieved such recent success?

Due to energy usage needing to be more conservational, there’s been a growing demand to utilise more natural resources. The sun is a potentially unlimited source of energy and because of this, the solar cable has been a great innovation over the last 10 years.

The process is known as photovoltaic, the method named for harnessing solar radiation and turning it into an energy source. Studies show that as of 2012, 100 GW was managed in the industry thanks to its being implemented in over 100 countries worldwide. This is a massive increase from the 5.4 GWp posted in 2005 and it just goes to show that solar energy has come a long way.

When compared to the manpower, cost and research needed for fossil and nuclear fuel energy sources, solar stands out as being much more effective. The common belief is that once solar energy eventually becomes our primary energy source, the non-polluting elements of the method will be a great benefit for Earth and its atmosphere.


One of the main factors to ensure successful solar harnessing is to have the correct solar cables. Typically, they are formed of rubber and although robust, lend themselves to degradation after severe weather exposure. Because of this, the outside layer needs to be of the highest quality to protect against all ranges of temperatures and climates. National certification for use is always advised so that the most economically and practically viable solar cable is found.

The YY Cable and Its Uses in Conveyor Belts

In any airport or distribution centre around the globe, you’re sure to encounter conveyor belts being used for the transportation of goods and services around the location. Airports are the most public example of its usage with YY cables being a helpful component to make them work to the highest quality.

The British Labour party has recently voiced concerns about the over-abundance of runways in airports yet with 34 million people attending Gatwick alone this year, it seems as if there may have to be more conveyor belts all over the country with YY cables supporting them.

YY cables are highly adaptable with the ability to twist them to many angles, making them a necessity to the constantly spinning conveyor belt. A standard cable would become stressed under the constant pressure but this is no problem with the YY, specialised in the ÖLFLEX® 140 range. Also, thanks to its oil-resisting nature, the cable is ideal for the mechanisms of the belt. Therefore, no matter the expansion of airports or the industrial section, then YY cables will be in-demand for the future for years to come.

The inception of the conveyor belt dates back to the later stages of the 17th century when although primitive, it was an essential help for transporting heavy goods such as grain sacks. Using a simple wooden bed made of leather, canvas or rubber.

In the early 20th century, the application of the belt progressed thanks to Hymle Goddard who patented the roller conveyor. It was not a rousing success with its usefulness being ignored until the coal mine and car manufacturing glory days with the former industry using a conveyor belt to this day at 60 miles long – the longest in the world.

During World War II, with the cost of war outweighing the cost of materials, synthetic materials were introduced as a cheaper alternative and they have mostly stayed that way to this day. A great range of materials are used today which go from PVC to steel.

Nitrogen Testing and how it can benefit your operations

Nitrogen testing is a popular way of testing the integrity of your hose assemblies. The process involves submerging the hose assembly in a water tank and running nitrogen gas through it. This makes it possible to spot leaks based on the emanating bubbles that would appear in the water. 

The process is something that should be carried out on pushed applications every few months, to ensure they stay safe and efficient. Defects in hoses can cause a huge range of problems for a number of people.

Defects and issues with hoses that help important processes can lead to outages and contamination, which can result in lost time, money and even cause harm to some of the personnel who may be involved with the process. By having nitrogen testing undertaken on your equipment, you are eliminating the chances of any unpleasant surprises, while allowing customers to carefully manage planned maintenance – maximising the time of their production life.

External damage inspection if often the first thing to check for with hose assemblies that are sent for testing, which is then followed by internal testing – undertaken with the latest endoscopic camera technology that will help find blockages, deposits, internal tears and other defects that could potentially go unnoticed.

After these visual tests are undertaken, the nitrogen testing (along with any other forms of testing that may be required) can take place. After all stages of the testing are completed, a full evaluation of the hose is created, stating whether the hose is safe and reliable enough to use. Buckley Industrial are a professional firm that can conduct all type of hose testing, from nitrogen testing, hydrostatic, hydraulic and much more.

Helium Leak Testing

Helium can be used to help find small leaks and sometimes larger leaks in applications as it is used as a tracer gas where concentration is measured.

Helium is in fact one of the smallest gas molecules and is inert, meaning it is relatively safe to use, as it will not react with any of the materials within the part that is being tested. In some helium leak testing applications, a mass spectrometer is tuned to detect helium – although it is possible to use a residual gas analyser.

Helium leak testing can be generally between one thousand and one million times more sensitive than using pressure decay techniques.

Advantages

By using helium leak testing, you are able to find the smallest leaks a lot easier than with other test processes, using a temperature stable and dry technique – which will in turn ensure you have a longer product life.

When the correct equipment is used, leaks can be detected, logged and the mass spectrometer can be reset within 20 seconds. This accuracy and reliability is then passed on to the clients who can commission the plant, knowing that it is completely leak free.

The whole process requires complex equipment and personnel that are trained, knowledgeable and experienced to ensure that the entire process is undertaken accurately and safely.

Helium is a very rare gas in the atmosphere, making it the perfect gas to find leaks with. Buckley Industrial offer helium leak testing with different levels of purity up to 99.99999% pure Helium (N7.)), which is available depending on customer requirements.

Buckley Industrial will not only offer the helium leak testing service, but specializes in a range of services that help ensure that quality vessels are used in applications throughout a number of different industries. They also supply a range of products that can cater for your every need when it comes to your important application.

Cable Assemblies and Contract Manufacturers

Cable Assemblies
Cable assemblies can be found throughout the technological world from house hold products to industrial equipment but their use in industrial technology is particularly important. Cable assemblies used for these purposes must be of the highest quality and created with the latest, cutting edge, tools. They must be as safe and efficient as possible as they are used in aircraft, aerospace, robotics, automation, agricultural machinery and much more. The testing and design processes on these cable assemblies are incredibly rigorous.

Cable assemblies are also known as cable harnesses and can be found in a huge variety of applications, in fact they are found everywhere where information or signals need to be transmitted. Cable assemblies are sets of wires supporting components such as retention systems, shielding and connectors.

Many manufacturers of industrial cable assemblies offer contact manufacturing services. This is an agreement where the original manufacturer contracts with another firm for the production of certain components.  This is useful for the parties involved as the builders of aircraft or farming equipment do not usually build their cable assemblies on site. This would be inefficient and not cost effective so they tend to outsource the construction of cable assemblies to cable specialists.

Specialists create a huge range of industrial cables specific to function. YY cables, solar cables, fibre optics, cable glands, cable assemblies and much more can be outsourced to cable specialists for use in industrial equipment.

Cable specialists give great value for money to other firms they work with as they provide a vast range and their services cover the design and the prototypes stage, right through to manufacturing, quality assurance and logistics support. Cable specialists design and manufacture the best quality cable assemblies and create custom cables for use in a wide variety of industrial applications.

Cable Harness Assebmlies play important roles across many industries

Cable harness assemblies are groups of wires that are bound up together to help increase organisation for use in applications. The number of wires found inside a cable harness will vary significantly, and are dependent on the type of application.

The technique is used by a huge amount of applications and establishments, commonly found in airplanes, cars, tube stations, modern shopping centres and much more. Cable harness assemblies are designed to suit a number of different environments and product applications, as certain applications may expose the cables to certain extreme environments.

Each specialist cable assemblies can be tailored to alter the material, size, weight and mass, with the outer jacket playing a huge role in the design. Cables can be optimised for high and low bending cycles, compressions, force and high traction for application in acids and other aggressive liquids.

Cable harness assemblies are heavily relied upon that maintains many of the industries that we use on a day to day basis. Without these, we would struggle and for example, the likes of an airplane or cat has to cater for many meters of cabling that make sure that it supports an application fully.

Without complex cable harness assemblies, we would be struggling to keep everything safe and organised – very unmanageable and unreliable. Thanks to companies such as Lapp, who specialise in cable solutions across the entire cabling industry, we are able to ensure that our applications and establishment employ the correct equipment to stay safe, reliable and efficient.

Lapp UK have over 40,000 products – and also offer custom design across a range of cables and products to suit your requirements.

Cable Harness Systems and Manufacturers

flickr.com/photos/a_mason
Many industries are huge users of cable harness systems and products to ensure that their applications run appropriately. Industries such as aviation, automation, oil, food & beverage, robotics and renewable energy all rely heavily on many of the systems offered by cable manufacturers.

Cable harnessing are very effective at maximising space, while maintaining a great level of protection to the individual cables that are harnessed inside of the housing. In the case of aircraft, there can often be miles of cabling that must be organised inside of the plane, which would be an extremely confusing process without the use of cable harness systems and techniques.

Thanks to the ease of assembly, it is possible to manufacture bespoke cable assemblies for nearly any electrical application. They can come in different lengths, diameters, wire ranges, and in various different resistant materials. The range of outer sheaths can combat UV rays, oil, heat, fire, moisture and cold, meaning that the cable assembly can be used in a huge number of different environments.

Many different cable assemblies are made of 100% recyclable materials and can be environmentally friendly. On top of this, there a wide range choice of terminals and connectors that can be attached easily, making it great for the input and output of electrical current, data and control.

Cable harnesses can vary from application to application. This means there is a huge demand for both standardised, ‘out the box’ harness systems, as well as custom versions that are made by cable harness manufacturers. Wire assemblies are generally calculated or individually specified to applications electrical and geometric requirement. This is always done using advanced computer software that ensures perfect measurements and to reduce human error. Stringent and methodical control is kept over the process to ensure assemblies high quality where the individual wires are cut to specified requirements and bound together to produce the cable harness.

Each aspect of a cable harness is considered before the final product is constructed. The environment in which a cable harness system can be used can vary greatly, from some needing to work at cold and high altitude conditions, whereas other may have handle degradation caused by salt in the air, or UV rays from the sun.                           

Lapp UK is a cable manufacturer and supplier firm that can offer cable harness systems, products, systems and anything else related to cable. For more information, products and anything else, see their website for more details.

Expansion Joints

Metal Expansion Joints
Expansion joints systems are an interesting alternative for pipes and pipelines. Expansion Joints such as these are able to be used in industries such as the oil, paper as well as the petrochemical industries, as well as a lot of other areas.

These are very diverse creations, and quite widely available. They are typically made to standard dimensions, and are able to reach from 1 to 100 metres in diameter and can withstand temperatures from -150°C to 2200°C. They can also resist a full vacuum or 2000 psig.

The market has been totally changed by the introduction of fabric expansion joints, because engineers have a new way to deal with thermal expansion as well as corrosive and abrasive problems.

These fabric joints are able to be used in applications for things such as turbines. Different fabric membranes and designs make it easy for joints to be used for turbines exhaust applications. Distinctive problems arise in the form of GTX, which are difficult applications which present challenges concerning performance and resistance over time. With the aid of fabric joints this can be solved much more easily.

Pipeline systems often use metal bellows to connect pumps and vessels. The folds in the design allows for superior movement in the axial, lateral and angular dimensions. To increase flexibility, other trimmings such as ties, pivots along with other trimmings. These devices have a lifespan, which depends on the shape, material along with the degree to which the connection must be able to bend to.

Metal expansion joints are crucial for pipeline technology as they are needed to counterbalance changes in length, this occurs in pipelines from changes in temperature, aside from this vibrations from pumps engines compressor or turbines are absorbed. Metal expansion joint are a cost effective option to increase the productive life of the pipeline system, making it run better and live longer. Designed to live as long as the system, the metal bellows reduce any sealing problems and the large space needed when dealing with other forms of expansion equipment.

FCCU Expansion joints are available; these need to withstand high temperatures and intense pressures, as well as aggressive environments and significant movements.
Expansion joints are great components and well used for the right application can make things incredibly easier and more efficient.

The importance of Wireline logging in the Oil and Gas Industry


The oil and gas industry relies heavily on wireline logging, to obtain a continuous record of a rock formation and its properties. The results then allow them to find out further properties, such as hydrocarbon saturation and formation pressure, which will make further drilling and production decisions a lot easier looking ahead.

Wireline logging is performed by lowering a ‘logging tool’ on the end of a wire line into an oil well (or borehole) and recording petro physical properties using a variety of sensors. Logging tools that have been developed over years measure the electrical, acoustic, radioactive, electromagnetic, nuclear magnetic resonance and many other properties of rocks and their contained fluids, allowing them to evaluate before looking ahead to reap the advantages.

Data is recorded at surface or in the actual hole. In an electronic data format that can then be either be recorded through printing or electronic presentation called a “well log” that is then provided to the client. An electronic copy of the raw data is made up and well logging operations can either be performed during the drilling process. This provides real time information about the formations being penetrated by the borehole, or once the well has reached a total depth and the whole depth of the borehole is able to be logged.

There are a variety of different types of wireline logs, which are often categorized by singling out their functions or alternatively by the technology that they use. “Open hole logs” are run before the oil or gas well is lined with pipe or cased. “Cased hole logs” are run after the well is lined with casing or production pipe. Wireline logs can also be divided based on what physical properties they measure, making up the different categorization methods.

Robertson Geologging are developers of slim-hole digital borehole logging systems and techniques and are also one of the largest global suppliers for slim-hole and bore-hole logging equipment.

Essential Control Cables

With the communication, transport and construction industries growing at a fast speed, every part that contributes to these sectors is valuable and integral to the system. This too goes for industrial cable. These fields cater for countless people and as a result need to be one hundred percent efficient, and of the highest quality. This ensures there are no errors when it comes to machines that may be critical for everyday life.

An industrial control cable wire is used in nearly every application which involves electricity. Each one of these is made specifically for a purpose of linking up equipment to each other, and controlling when they are used or not. They are various types of them and, and each is specific to purpose. In an environment where there is light stress on the cable and they will need to take this stress, whether in wet or dry conditions. These cables will be able to withstand the pressure. A telecommunication cable can be like this.

Other kinds of industrial control cable that can be used in applications where there is a necessity of equipment which will continue to work without any interference of stoppages. These cables need to be able to handle a high amount of pressure, and thus are installed with multi-cores and tinned copper wire braids which protect the cables fro, stress and external electromagnetic pressures.

Some of the toughest cables come with galvanized steel round wires or galvanized flat steel strips which make them compatibles enough for the hardest of applications. All kinds of control cables are equipped with plain copper conductors and AC voltage rating up to 1100V and 1500V they are also armoured with a covering of PVC compound for added strength. Vigorous testing and checks take place to ensure that every industrial cable that is placed into the market reaches standards as well as being armoured with strong compounds, ensuring that they are ready for external applications.

Hydraulic hoses

Hydraulic hoses are high pressure tubes which are often made from synthetic rubber, Teflon or thermoplastic. It is designed for carrying fluid around within hydraulic machinery. Hoses such as these come from a number of different brands and specifications, varying with each. They are most commonly used by construction and mining operators, power generator companies, maintenance professionals, gas drilling companies and other sectors.  The hydraulic systems came into prominence when engineers discovered that is light in weight, self-lubricating and compact in size. As flexible hydraulic hoses were developed, a wide range of machines which utilized this technology came into existence.

These hoses could pump water in order to operate a moving piece of machinery. The fittings are connected to other devices and they transmit hydraulic power to it. Various kinds of brad adaptor fittings attach to this application. Other things pumped through the hoses include water; grease, LPG, refrigeration fluids, fuels and natural gas are also transmitted. Other types of fittings used on these pipes include O-ring, face seal, flare less and elbow.

The O-ring includes many threads and resembles an ‘O’. Threads such as these are screwed on securely to obtain a tight connection. These fittings are either male or female, and can handle designated pressure.

Elbow fittings are available in different sizes. Both of these ends of the pipe are connected at the specified angle. These are mostly used for different kinds of applications of plumbing. Female and male fittings connect together to complete the connection appropriately.

Hose pipes are used for any instances and therefore it is important to know how to choose the right hose for the right job. These include medium pressure, high pressure hydraulic pipes, flexible low bend radius pipes and so on and so forth.

Hydraulic pipes can be used to create a strong torque of low speed; this can move machines with absolute precision. The hydraulic pumps can control various machines through these hose pipes at a varying level of power, and can operate safely in various situations.

Hose pipes have ratings depending on their pressure limits. The temperature and fluids it is designed to carry. Ratings are often printed onto either the pipe or the fittings.

The History of Wireline Logging in a Nutshell


Wireline logging is an industry specific term used commonly in the oil and gas industry, which involves lowering a logging device attached to a wire line into a borehole or oil well - to measure the properties of the rock and fluids of the formations.

The measurements that are obtained from this process are then interpreted and used to help determine the depths and zones where oil and gas will be expected to be found.

Wireline logging has a history that goes back over 85 years ago, where two brothers; Conrad and Marcel Schumberger ran what is considered to be the very first wire line log at the Pechelbronn Oil Company in France.

The logging process was a success and the two brothers named their new technique an electric survey. A few years later and the term ‘well log’ was being used in the USA. Wire line logging also became used, as the logging tool is lowered through the oil well or borehole on the end of a wireline.

Wireline logging tools are typically cylindrical in shape and range from a narrow diameter of around one and a half inches, up to around five inches. There are in fact three different basic types of wire line logging tools:

1. The first type measures the spontaneous potential, where the difference in voltage between an electrode in the wireline logging tool - where it is operating in the oil well or borehole, and another located on the surface. This allows the measuring of temperature and pressure, due to the natural radiation coming from the natural isotopes.

2. The second type of wireline logging tool has a source of excitation or stimulation as well as a sensor. The sensing systems in this type can be magnetic resonance, inductive, electric, and acoustic or other methods.

3. This tool is used to perform a kind of mechanical manoeuvre, where the kind of wire logging tool can retrieve rock samples at various depths to get the data for scientists to physically examine. When the formations are examined closely and carefully, you are able to draw some conclusions regarding depths, before continuing with the extraction process.

There are a number of electric log tools available for use, which can be categorised whether they are open hole logs or cased hole logs. Electric logs are defined through the physical properties that the tool measures, when the specific resistance of the rock and fluids are measured it is resistivity log. When the rock has its level of pore percentage measured, porosity logs technologies are used that are based on sound waves or nuclear reactions.

Wireline logging allows the acquisition of valuable data at a fast rate and over a wide range of depths, allowing fast and accurate decisions to be made regarding drilling, based on the information obtained. Understanding the physical properties of the oil well allows the proper management methods and techniques over its lifetime – and wire line logging makes that possible.

Why Should I Use Low Smoke Halogen Free Cables?


Have you ever been wondering whether you need low smoke halogen free cable for your applications? Here you will find out all of the key information surrounding low smoke zero halogen cables, their advantages, disadvantages and common uses.

First off, what are Halogens?

On the periodic table of elements, there are specific groups that several elements belong to, with halogens such as fluorine, chlorine, bromine, iodine and astatine making up the group. Halogens are found in many of the products and applications that we come across in day to day life – for example; fluoride in almost all toothpaste, chlorine used in pools and iodine something commonly found in medicine cabinets.

Other Halogen Uses

Beyond our everyday contact with halogens, there are also numerous other ways in which halogens are used. Halogens are found in cable jackets as a flame retardant, which includes PVC (polyvinylchloride). Coincidently, this flame retardant chemical can cause some health problems for people - although halogen compounds keep from catching and spreading fire, they release hazardous gases if the cable does come into contact with flames. Carcinogenic substances such as Polychlorinated Biphenyls (PCBs), Polycyclic Aromatic Hydrocarbons (PAHs), Nitro Polycyclic Aromatic Hydrocarbons and dioxins are all toxic chemicals that can be formed when these halogenated compounds are burned. These gaseous compounds are not only hazardous when they have burned and are in the air, after coming into contact with water they can condense into caustic acids.

A Safe Alternative

Low Smoke Low Halogen is a very good description of what these cables can actually do. These cables are much safer during a time where flame comes into direct contact to the cable jacketing, ensuring that very little smoke and no toxic gasses like a PVC cable would. Low smoke zero halogen cable is the safe choice for locations in which there is a fire potential and the potential for people to be near the fire. Low smoke halogen free cable also complies with the European Union’s Restriction of Hazardous Substances (RoHS) directive and similar North American safety and environmental standards.

The basics of LED strip lighting


LED tape, also known as LED strip lights or LED ribbons are different lighting options that offer a lot of versatility, which afford users a means to produce professional lighting setups with only a fraction of the effort and time it takes to put up other forms of lighting.

Voltage

LEDs that come with a self-adhesive back usually run on twelve volts and can cut up every two centimetres depending on the kind of lighting strip you have chosen. The usage of LEDs equate to the power consumption at a much lower value as opposed to older light sources. Research has shown the LEDs have a much longer lifespan with an expectancy of around ten years onwards. This makes LED lighting an extremely cost efficient solution to any user over a significant period of time.

Major LED Types

Single coloured and alternating colour are two main types of LED lighting available on the market, ranging from cool to warm colours. Generally, it is ideal if the light is there for a subtle effect, somewhat offering an ambience rather than main source of lighting. Many people use these lights to mount them on the underside of cabinets and kickboards in order to produce an appealing and functional lighting system – however they work just as well when used to highlight or produce accent lighting to enhance a homes atmosphere.

LED Light Selection

There is a special kind of LED that is in fact colour changing, managing to blend RGB light at the source point to produce a wider range of colour. Like the single colour strip, the colour changing LED strip can be utilized for various applications as well as while permitting a user to switch from a static to dynamic colour choices, with a diverse unit of control. There are various factors to consider when selecting LED lighting, including IP rating, chip size, brightness, length and driver.

Brightness Levels

The brightness or power of a ribbon varies dependant on the size and number of LEDs utilized. LEDs used by the tape are in fact a compressed version called Surface Mounted Devices (SMDs). These come in two sizes; 3258 for small and 5050 for the larger ones. Depending on the number of LEDs, there will be a greater number of LEDs that will increase the brightness, while less LEDs per metre will produce less power.

Drivers

LED drivers are needed for LED tapes run on a direct twelve volt current, which will bring down the voltage of the mains. These can be bought separately, or in a kit and a maximum load is common for many drivers; which must be good enough to control the light's power consumption. Should you wish to use LEDs outdoors, you can find ones suitable for this. Alternatively, waterproof and splash proof coating are applied on strips thus allowing them to be used to light areas that can be prone to moisture (outside, kitchens and bathrooms).

Thankfully, LED lighting is highly customisable and can be cut to certain requirements to allow you the ability to customise anything your heart desires. LED illuminations can cater for all of your lighting needs, so check out their website now!
