Why LED and how to understand parameters

LEDs are better at placing light in a single direction than incandescent or fluorescent bulbs. Because of their directional output, they have unique design features that can be exploited by clever designs. LED strip lights can be installed under counters, in hallways, and in staircases; concentrated arrays can be used for room lighting. Waterproof, outdoor fixtures are also available. Some manufacturers consider applications such as gardens, walkways, and decorative fixtures outside garage doors to be the most cost-efficient.

LED lights are more rugged and damage-resistant than compact fluorescents and incandescent bulbs. LED lights don't flicker. They are very heat sensitive; excessive heat or inappropriate applications dramatically reduce both light output and lifetime.


Term Definition Unit How to interpret
Color Temperature Color of light Kelvin (K) Sunlight at sunrise is 1800K 100W Incandescent light bulb is 2850K Overcast Sky is 6500K
Color Rendering Index (CRI) Light’s effect on color Scale of 0 to 100 with sunlight at 100 The higher the number, the more “true” the color will look in that light
Brightness The intensity of the light. Lumens The higher the lumens, the brighter the light
Power Amount of electrical energy consumed Watt Lower the watts, the lower the energy consumed
Efficiency The efficiency of the bulb to convert electricity into light Lumens per Watt More efficient bulbs provide more light using less energy


How to interpret:


Color Temperature: Color of light, Kelvin (K): Sunlight at sunrise is 1800K 100W Incandescent light bulb is 2850K Overcast Sky is 6500K
