Commercial LED Lighting
Earlsmann's range of energy efficient commercial LED lights are ideal replacements for old, inefficient lighting. They run cool without the need for heavy external heatsinks and have a service life up to 50,000 hours thus reducing maintenance. Due to their high efficiency, these luminaires are extremely environmentally friendly and will help significantly with carbon reduction programmes. Included in the range are internal and external luminaires and a range of replacement products.
LED power saving - a brief explanation
It is not possible to directly compare the lumen output from an LED light with traditional lamps due to the way they emit light. LED efficacy is around 65-90 lumens per Watt whilst a compact fluorescent (CFL) is 50-70 lumens per Watt, This suggests that, Watt for Watt, they are similar so, in other words, 25 Watts of LED gives the same output as a CFL, around 1750, say.
However, the LED is very directional and, typically, the output is at 120o. A CFL output is 360o and relies on reflectors to get the light where required. Typically this can mean a 15 Watt LED source producing around 1000lm will appear as bright at the working surface as a 25/30 Watt CFL. Light level at the working surface is measured in Lux. It is the "Lux" level, therefore, rather than the lumen output, which is the most reliable comparison.

LED Replacement Lamps
When the existing luminaire is in good condition it may be preferable to simply replace the lamp. Our replacement LED range includes dimmable GU10 and MR16, PAR 38, LED fluorescent tubes and 2D.

Standardisation - IESNA LM80 2008
With so many manufacturers and suppliers of LED lighting it has become increasingly difficult to make comparisons between all the claims about different parameters such as life, colour stability, light output etc. A new standard, LM80 should help this situation. Manufacturers are now starting to test to this standard so it is wise to read through the test report before selecting.. Earlsmann use Philips LEDs. Download their test report here or go to our resources pages to see all our downloads. LM80 makes no reference to temperature control. Please ask us about how our modules have self regulation to ensure the maximum operating temperature of the LED is never exceeded.
Earlsmann's LED lighting is approved by the Carbon Trust so are suitable for inclusion in a loan application. If you are an SME, which means a turnover less than £43m and have less than 250 full time equivalent employees, then you may be eligible for an interest free loan. Please contact us if you would like to discuss this further.
