Author name: Brent Ehrlich Blog Category: BuildingGreen's Top Stories GreenSpec Insights LED light quality is still not very good, but a new California standard could change that, and prevent another CFL -style consumer rejection. Cree's TW Series LED Bulb provides impressive 93 CRI light quality yet costs less than $20. Photo Credit: Cree LEDs provide some of the most efficacious lighting available today, with some products offering over 100 lumens per watt, or lpw—an incandescent bulb is a paltry 15 lpw. Unfortunately, as consumers know from compact fluorescent lamps (CFLs), which have never been fully embraced, energy efficiency can come at the cost of light quality. Unless something changes, LEDs could become the next CFL, offering energy efficiency at relatively affordable prices, but with poor color and durability and limited dimming ability. In this month’s Environmental Building News, we look at two products, Soraa’s MR16s and Cree’s TW Series LED Bulb, that offer innovative LEDs with demonstrably superior light quality to standard products (see Soraa: New LED Technology With Improved Color Quality ). These lamps, however, are an anomaly in an LED industry where light quality plays second fiddle to efficacy . read more
