General lighting

What are LEDs?
LED stands for "light-emitting diode." LEDs are small light sources that become illuminated by the movement of electrons through a semiconductor material. 


What are the benefits of using LED Lighting?
LED lighting is the most energy-efficient lighting in history, producing energy savings of up to 80 percent when compared to traditional halogen lighting. XGL LED lamps are rated with an average life of over 40,000hrs, all while being able to deliver superb thermal management and incredibly reliable and consistent light output. LED PAR38 Lamps, for example, incorporate high-performance LED chips and full retrofit dimming capabilities, resulting in the most sophisticated, functional and flexible lighting solutions available. A 20W lamp outperforms a traditional 150W lamp in every category, with a power factor of >0.7.

In reference to LED luminaire technology, what does COB refer to?
"COB" or "Chips On Board" is a new LED packaging technology specific to luminaire LED light engines. Multi-LED chips are packaged together as single lighting modules, which, when powered, produce highly efficient "lighting panels." COB products are increasingly popular because of their ability to increase light output 10 times more than standard LED solutions.


What is thermal management and why does it matter when it comes to which lamps I purchase?
Temperature is the primary factor that limits the lifetime and light output of a lamp. It is common knowledge that electronic components do not perform as well, or last as long, when exposed to heat. A typical lamp will lose half its lifetime for every increase of 10 degrees Celsius, and this applies to all lamp technologies. In ceilings, temperatures can rise to 65 degrees. The best performing lamps will have a well-balanced combination of chip and heatsink, which will provide the most consistent light level and colour over the longest lifespan. Overall, the stated power of an LED lamp is no real indication of a lamp’s performance if heat is not managed properly. 


What is efficacy?
Efficacy is a term used to describe the efficiency of a lamp, which is measured in lumens per watt. To determine the efficacy of a lamp, divide the lumen output of the lamp by the watts consumed.
