Cost of LED Lighting
The opportunities to replace conventional lighting with LED lighting for general illumination are growing, fueled in part by the continual advancements in LEDs and the global need for energy-efficient lighting alternatives. Performance is an important metric for assessing the viability of replacement by LED sources. These devices that once merely lit calculators and cell phone displays can now illuminate an airport terminal or a 100 foot building façade. They increasingly match or exceed the efficacy of conventional lighting sources, particularly with the advent of today’s power LEDs. In fact, the efficacy of LED sources, measured in lumens per watt, is eclipsing that of incandescent and halogen sources.
