LED UK is an International Company specialising in the supply of LED products. We operate on a global network in a diverse group of industries from Industrial & Commercial, Hazardous Area, Office & Retail, Stadiums & Arenas etc...
LED technology is now at a point where product longevity can reach more than 100,000 hours. At LED UK we therefore focus on the long term needs of our clients and products. Ownership costs and maintenance plans can often be overlooked, we ensure there is no oversight or hidden costs for the product throughout its use. We provide the highest quality LED based products by integrating premium components to optimise product performance and reliability.
The LED Equation
The conversion formula to realise the benefits of our LED technology
QL = P + M = S
(QL= Quality LEDs, P = Power, M= Maintenance, S = Savings)
The result = investment in our quality LED lighting means savings of over 60% on your current incandescent based lighting and it’s on going maintenance.
- Why should I use LEDs?
- High efficiency and longevity are the two distinctive features of LED light sources. Thanks to the 50,000 + hours lifespan of our LED's the maintenance of luminaries is significantly reduced (cleaning only). This provides savings over energy and maintenance costs and the overall cost of ownership.
- Do LEDs save money?
- Research by the Department of Energy suggests that ENERGY STAR-qualified LEDs use only 20%-25% of the energy as incandescent and last up to 25 times longer. The initial cost of the LED may be higher than alternatives but payback is often quickly made in the energy savings. Just like any technology buying initially cheaper variances will mean short term gain but long term it is best to focus on high-quality products with genuine warranties.
- What impact do they have on the environment?
- LEDs do not contain any harmful chemicals or heavy metals. Compact Fluorescent lights contain mercury which is highly toxic. Both incandescent and CFL lights emit a small amount of UV radiation whereas LEDs emit none. A large percentage of energy comes from the burning of fossil fuels. This in turn releases greenhouse gases into the atmosphere. Less energy needed to facilitate the use of lights means a decrease in the amount of fossil fuels being burnt. Using LED light sources will contribute greatly in reducing your carbon footprint.
- How long is 50,000 hours?
- 24 hours per day: 5.7 Years 18 hours per day: 7.4 years 12 hours per day: 11.4 years 8 hours per day: 17.1 years
- What is CCT?
- The correlated colour temperature (CCT) is a general measure of "warmth" or "coolness" of light produced by the light source. The light emitted by a light source is rated against a reference source when heated to a particular temperature, measured in degrees Kelvin (K). Light sources with a CCT rating below 3200 K are usually considered "warm" sources, while those with a CCT above 4000 K are usually considered "cool" in appearance. The choice of colour temperature provides lighting best suitable for each application.
- What is binning?
- This involves how we perceive colour as we are very good at seeing differences in the colour or chromaticity of light. LED's are manufactured in batches each with a ï¿½bin ratingï¿½ In order to provide colour balance choice of bin rating is critical to optimise performance. Because so many LEDs of different chromaticity or CCT are produced, they must be parcelled up, or binned, into a selection of chromaticityâ€™s within which the majority of people will not perceive a noticeable difference. The boundary regions tend to be sized based on a set of MacAdam ellipses and a set of quadrangles. Bins tend to be located around the black body (or Planckian) locus (BBL) which is a line that denotes pure white light as produced by a glowing body at different temperatures. It is a line in colour space because the hotter the body gets then the colder the light gets.
- What is colour rendering?
- The colour rendering index or CRI is a measure of a light source's ability to render the colours of an object realistically, or, naturally compared with a familiar reference source, either incandescent light or daylight. The colour rendering index is a set of ratios that provides a quantitative measure of the capability of a light source to reproduce the colours of various objects faithfully in comparison with an ideal or natural light source. Under the worst types of light source for colour rendering, such as the low-pressure sodium lamp, most colours are not rendered well at all resulting in a poor illumination quality. Gaps in the spectra of a light source will lead to poor colour rendering. For example, shining orange low-pressure sodium light on a green apple will make the apple look grey because there is a shortage of colour in the light source that can reflect the green part of the spectrum from the apple.
- What is an IP rating?
- An Ingress Protection (IP) rating consists of two numbers which denote the products resistance to foreign objects (first number) and liquids (second number). A greater value means a greater resistance. Classifications for IP ratings can be found in the British Standard document EN60529.
- What is pixel pitch?
- Pixel pitch is the distance between the diameter of the LED light source (or pixel) measured in millimetres. Choice of pixel pitch is based on the optimum viewing distance required
- Do LED light sources radiate heat?
- Unlike incandescent light sources LED's do not radiate discernible heat. This is controlled by the incorporation of heatsinks and their quality is critical to both performance and longevity of the product.
