1. Q: What does LED stand for?
A: LED stands for Light Emitting Diode.
2. Q: What is the difference between an incandescent bulb and an LED?
A: Incandescents create light by filament. When power is applied, the filament glows, generating heat, in turn, producing light.
LED is more efficient and energy saving by creating light though a “cold process”- When power is applied to semiconductors (usually gallium, arsenic and phosphorus), they’re stimulated by the movement of electrons; thus creating photons, the light that is visibly seen by humans.
3. Q: Why do LEDs use such little power?
A:LEDs produce very little heat and do not use filaments, so the energy transfer to light is more efficient.
4. Q: How long do LEDs last?
A: With good quality, LED Lighting can last for more than 50,000 Hours before it loss 30% its Lumens. As LEDs get older, they tend to dim and fade but aren’t susceptible to blinking like incandescent or fluorescents.
5. Q: How do you evaluate LED products?
A:There are 3 important factors to LEDs: system efficiency, optical control, thermal management.
