LED Lighting Installers
Isn’t LED installation difficult?
One of the most common questions we get about our LED lighting is whether or not you’d need to change your light fittings to be able to enjoy LED products. The short answer is no! Our LED products are what we call retro-compatible; they’ll fit just where your old bulbs and tubes were. We’ll only install new fittings if you want them.
So who will install your new LED products?
Elite’s LED lighting installations will be carried out by our own team of specialist LED lighting installers, supported by our sister division Elite. They are fully NICEIC accredited so you can have the confidence that in the unlikely event that electrical work is required, a qualified electrician will be at hand. All on-site employees are Disclosure Scotland vetted. In rare circumstances, usually when it provides the most cost-effective solution for the customer, Kellwood may sub-contract the installation work to one of our approved LED installers. All partners will achieve the same high standards of quality Kellwood expects from itself.
What if my lights are hard to access?
Elite’s LED Lighting has a comprehensive range of access equipment to ensure that we can carry out LED installations efficiently and with minimum disruption for the customer. Equipment includes vertical boom lifts, scissor lifts and cherry pickers, all capable of working to a height of approximately 10 metres. All operators are fully trained and experienced in handling any plant we bring on-site. Where more specialist equipment is required, Kellwood Electrical will utilise one of its approved suppliers.
Minimal Disruption – Installation When It Suits
Elite fully understands the importance of minimising any disruption during your LED lighting installation. Factories cannot afford to stop production, offices cannot shut for the day and traffic must remain free to move! Kellwood is willing to discuss suitable access times to avoid these inconveniences, whether this means working at weekends or out of hours.
The Benefits of LED
- Reduce your Energy Bills by up to 90%: LED lights are an extremely efficient light source. They use much less power to produce the same brightness when compared to traditional lighting. Nationally, electricity prices have risen by 52% over the last 5 years (UK Government Statistics – Department of Energy and Climate Change). With this trend set to continue in the next five years, LED lighting solutions are increasingly appealing.
- Pay only for the light you use: Many of our LED products are highly adjustable. Unlike fluorescent predecessors like tubes which waste light by sending it in the wrong direction, our LED products cast light only where you direct it. This means you only have to pay for the light falling on your desk, without the additional expense of light lost through the luminaire into the ceiling space.
- Reduced Replacement Costs: LED lights last significantly longer than traditional bulbs. A typical LED light bulb will be guaranteed to 30,000 hours; however our LED products are expected to last well over this; 50,000 hours and more! This means that the constant replacement costs of traditional bulbs far outweigh the initial investment and installation
- Reduced Maintenance Costs: The lengthy lifespan of LED bulbs means that maintenance costs are significantly reduced too. The actual labour cost of having to replace traditional bulbs when they blow once a year is often difficult for organisations to calculate, however it can be alarmingly high! This is particularly relevant for bulbs found in difficult and “expensive” to reach places where a simple step ladder is not an option; above stairwells, atriums, busy roads, production lines and on offshore structures are just a few examples of where companies and organisations can enjoy the “Fit and Forget” stance associated with LED bulbs.
- Grants and Financing: There are many public and private sector grants and financing options available for new LED lighting installations. In many cases, you can consider your lighting upgrade as free!
- Reduced Carbon Footprint: In an age where organisations are becoming increasingly aware of their carbon footprint, environmental responsibility and corporate image, LED lighting is very appealing as an opportunity to meet carbon reduction targets.
- No Mercury: unlike fluorescent lights, LED bulbs do not contain mercury so don’t require special recycling or disposal procedures. This is highlighted by a reduced WEEE Charge for LED lights.
- Reduced Light Pollution: LEDs produce directional light. This means that light pollution can be minimised; an advantage for street lighting, particularly in “dark sky zones”.
- Zero UV or IR Radiation: LED light bulbs produce no ultra-violet or infra-red radiation. This is especially useful in museums and homes where conventional lights can damage sensitive fabrics, exhibits, wallpapers etc.
Health and Safety
- No Glass: High quality LED light bulbs are made from a solid array of LEDs accommodated in a robust plastic housing. For industries where glass can cause huge amounts of down-time if broken glass infiltrates production, LEDs can offer a fantastic alternative while also reducing insurance costs. This is common in food manufacturing where glass cannot be picked up with standard food x-raying equipment during quality control.
- Hygienic: Some LED lights come as fully sealed units as opposed to lights in an “open” reflecting luminaire. This means that dust and insects cannot gather inside the unit, leading to additional maintenance costs and hygiene concerns. This advantage over traditional lighting is often utilised in hospitals, food processing factories, care homes and other health-conscious organisations.
- Reduced Fire Hazard and Risk of Burns: LEDs produce “cold” light, reducing the risk of burns and fire hazards. Consequently, installing LED lighting can reduce insurance costs.
- Fully compatible: There is a retrofit LED product for almost every luminaire or an equivalent LED product for any traditional light bulb available in today’s market. It is as simple as “changing a bulb”! This means that virtually no additional expenditure is required when upgrading to LED lighting. The only exception to this rule is when traditional “tube” luminaires may require their starter ballast by-passed to optimise the retrofit LED’s efficiency.
- Improved Light Quality: LED lights don’t flicker or strobe. They can have a consistent, high Light Rendering Index revealing “true colours”. Panel lights provide a uniform blanket of light.
- Aesthetically Pleasing: LED bulbs are compact, especially when compared to Energy Saving (CFL) Bulbs.
- Robust: LED light bulbs are considerably more robust than traditional lights (containing glass, filaments and pressurised gases). They are also available in a comprehensive range of IP Ratings. The electrical components are not housed in inert gases and Kellwood sources bulbs with Japanese diodes and capacitors ensuring superior quality. This makes them very suitable in vibrating and other “hostile” environments.
- Instant Light and Dimmable: unlike Energy Saving CFL Bulbs, LED lights achieve maximum brightness immediately. LED tube lights don’t require expensive-to-run starter ballast. Some specially designed LED lights can be dimmed, allowing for much more control of your lit environment.
- Temperature Optimisation: LEDs work particularly well in cold environments. They are typically tested at 20 degrees Celsius and will perform even better than their “spec sheet figures” in temperatures below this, e.g. cold stores and industrial freezers. LEDs produce “cold light” and many organisations find that they save as much money on “secondary system” costs, e.g. air conditioning, as the direct electricity savings associated with running LED lighting!
What are LEDs?
The ‘latest technology on the market’, whatever it is, always comes with its own baffling jargon. On this page we hope you’ll find the answers to any technical questions you might have.
LED – (Light Emitting Diode)
An LED light bulb is constructed from many small electrical components called LEDs. These are made from a semiconductor material and are a very efficient light source when manufactured and wired correctly. The voltage across the LED must be greater than a set value to ensure it works, however the electrical current passing through it should not be greater than a maximum threshold.
A driver ensures that an LED has a steady energy supply so that the LED is not damaged by large electrical currents. Typically most LED lights have their driver built into them, however in some circumstances (like low voltage 12 Volt bathroom lighting), the driver is installed separately for safety reasons.
Light Rendering Index (LRI)
This is a number between 0 and 100 that represents how good an LED lamp is at displaying the correct colour, i.e. making sure that a blue jumper appears to be blue when displayed under the light. A figure of 100 is perfect. A figure less than 70 (like traditional low pressure sodium street lights) is poor. The human eye will struggle to be able to tell the difference between two bulbs with LRI 10 units apart. It should be noted, however, that this is an average for the whole range of visible colours – some lights can appear to have an acceptable LRI, yet be poor at displaying a niche colour!
This is a figure that indicates how “warm” or “cold” the light is. There is no rule for this; it is down to personnel preference. Typically lighting for homes is quite a warm light (about 3000 Kelvin), whereas for commercial applications, lighting tend to be slightly colder – or whiter – (in the range of 4500 to 6000 Kelvin). Note: “colder” lights tend to be slightly more cost efficient!
This is how bright a light is (the unit of measurement is “lumen”). One of the critical things to consider when choosing LED lighting is that you are comparing light-for-light, not like-for-like. Assuming you are happy with brightness of your current lighting, the concept you want to be aware of is Watts per Lumen i.e. “how much less energy do I use to create the same level of brightness.
The IP rating (range 00 – 68) of an LED light indicates how exposed the internal electrics are to direct human contact (electrocution) and from solid contaminants and how well it repels water. For example, a low IP rating would typically mean that the bulb is designed only for indoor use and should be installed out of reach of human contact, whereas a very high IP rating may mean it can be submerged under water for extended periods
