LED-based products are poised to replace legacy light sources in virtually all general lighting applications indoors and out while also finding substantial use in many other places ranging from automotive headlamps to life-science
applications such as horticulture and maintain a strong presence in backlight and display.
LEDs offer the most sustainable—and exciting—alternative to incandescents. For starters, they’re highly efficient: The average efficacy of an LED bulb is 78 lm/w (lumens per watt), compared with around 13 lm/w for an incandescent and approximately 18 lm/w for a halogen equivalent. Yes, LEDs have their shortcomings: Buying an LED bulb doesn’t seem as intuitive as picking up an incandescent from your local drugstore, and the up-front cost is high. But once you get to know the technology and the incomparable versatility that LEDs offer, you’ll see the demise of the incandescent as an opportunity.
