LED has many strong points
Abbreviation of light emitting diode, an electronic device that lights up when electricity is passed through it. LEDs are usually red.
LED has many strong points:
1. Long life – lifetimes can exceed 100,000 hours, as compared to 1,000 hours for tungsten (incandescent) bulbs.
2. Size: typical package is only 5 mm in diameter.
3. Energy efficiency – up to 90% less energy used translates into smaller power supply required
4. Non-toxicity – no mercury
5. Versatility – available in a variety of colors
6. Cool – less heat radiation than HID or incandescent
7. Low voltage and DC – more secure in some applications
