Are LEDs energy-efficient?
LimeLumi best white LED products can meet or exceed the efficiency of compact fluorescent lamps (CFLs). Many white LEDs currently available in consumer products are much more efficient than incandescent lamps. The best warm white LEDs available today can produce about 8-100 lumens per watt (lm/W). In comparison, incandescent lamps typically produce 12-15 lm/W; CFLs produce at least 50 lm/W. Performance of white LEDs continues to improve rapidly. However, LED device efficacy doesn’t tell the whole story. Good LED system and luminaire design is imperative to energy-efficient LED lighting fixtures. For example, a new LimeLumi LED recessed downlight combines multicolored high efficiency LEDs, excellent thermal management, and sophisticated optical design to produce more than 700 lumens using only 12 watts, for a luminaire efficacy of 60 lm/W. Conversely, poorly-designed competitors luminaires using even the best LEDs may be no more efficient than incandescent lighting and may fail well bef
