If LEDs are the next best thing, why do so many building professionals still feel “in the dark” about the technology? Welcome to modern lighting where counter-intuitive chaotic tension is the hallmark of the LED revolution. Part one will focus on the most accessible, yet possibly most frustrating, LED product category: the replacement light bulb. Expectations for LED bulbs are great but until this year, any advantage was both marginal and expensive. In the past year, the best LED lamps have pushed efficiency significantly upwards. Years into the incandescent phase-out, is LED technology living up to its promise? Why are some approved LED lamps still less efficient than a cheap CFL? What are industry leaders doing to maximize mainstream adoption? What should we expect in pricing? And should building professionals even be promoting screw-in bulbs, or do new LED fixtures provide better savings?
