Every industry thrives on new and forward thinking technology. While LEDs aren’t new, in recent years their performance and reliability have improved to make them a more viable option for general and task-oriented lighting. EiKO LEDs save time, money, and energy by using top-quality Cree chips for long life, superior lumen and color maintenance. They also feature instant, flicker-free start-up and no off-state power draw.
LED INFO
The ratio of light output (in lumens) to input power (in watts) expressed as lumens per watt(LPW).
CRI is color rendering index, a measure of the degree of color shift that objects undergo when illuminated by the light source as compared with those same objects when illuminated by a reference source of comparable correlated color temperature. The maximum CRI is 100.
CFL is a compact fluorescent lamp, a family of single-ended fluorescent discharge light sources with small diameter [16 millimeter (5/8 inch) or less] tubes.
Amps (watts) is the current rating at design voltage or the power consumption in watts of he lamp. In the case of dual-filament lamps, the values for each filament are given.
