How do LED lights differ from traditional light sources such as incandescent bulbs, fluorescent lights and high intensity discharge (HID) lights?
Unlike other sources of light, LEDs covert electricity directly to visible light and do not produce heat or other forms of radiation such as ultra-violet light. Traditional illumination sources radiate light evenly through 360˚. LEDs radiate light in a fixed arc. This has advantages in some applications and presents some challenges when designing lighting fixtures to use LEDs.
