Converting your old high-intensity discharge (HID) fixtures or Metal halide bulbs to LED is simple with this retrofit bulb. It will emit 15,600 lumens of cool white light with just 120 watts of power. Not only does it save energy, but it’s also much brighter than your old fixtures. This LED bulb is designed to replace 320-400 watt MH bulbs and lasts at least twice as long. This reduces costly repairs, disposal fees, and replacement costs. It has an aluminum cooling heat sink and a shatterproof polycarbonate lens. With a mogul screw base, the bulb can be installed in any fixture with an E39 socket.
