LED lamp output values (Lumens) can vary dramatically depending on which values are being quoted. The following information may assist in selecting the right product for the right application. Raw Lumens This is a measure of the theoretical output of a light. Raw Lumen output is calculated by multiplying by the theoretical rated output of the LEDs by the number of LEDs in the lamp. Example: 8 LEDs rated at 100 Lumens per watt 8 x 100 = 800 Raw Lumens Effective Lumens This is a measure of the actual output of a light. The Effective Lumen output takes into consideration electrical and real world losses (ex. thermal, optical, and assembly), so it is a better representation of the useful visible light that is actually produced. Example: Raw Lumens = 800 Thermal, Optical & Assembly Losses = 40% (of Raw Lumens) 800 – 320 = 480 Effective Lumens What do you mean by Thermal Losses, Optical Losses and Assembly Losses? There are inherent losses associated with any lamp

Lasers, projectors, LEDs. No, this isn’t some party planner's material list, but the headlight technology that has been advancing at a rapid rate and is finding place on our cars. And, it's getting more and more difficult to cut through the jargon; LEDs, halogens, projectors, xenons. So, what do they mean? What are halogens? A halogen bulb is similar to an electric bulb found in any household. But while your regular bulb has a filament (small wire) that heats up and emits light, the halogen lamp uses halogen gas to increase brightness. These bulbs aren’t very efficient, as most of the energy is wasted in heat instead of light. Halogen bulbs used in automobiles typically emit a yellowish light and despite the technology being over 50 years old, it is widely used. In terms of brightness, halogen lamps have a throw of about 100 metres. What are xenon headlights? Also referred to as HID (high-intensity discharge), xenon lamps are similar to the ubiquitous tube light. There is
