this LED light has SMD LED with an output of 5,500 lumens. Natural white LED have a 4700K color temperature and emit a wide 180° beam angle. This powerful, energy-efficient LED light fixture uses just 50 watts of power-significantly less than the 128 watts that would be consumed by a metal-halide (MH) fixture. And with a life expectancy of 50,000 hours-5 times as long as fluorescent or MH fixtures-the LED light reduces costly repairs, disposal fees and the need for replacements.
