Use this LED retrofit bulb to easily convert metal-halide (MH) and other high-intensity discharge (HID) lights into long-lasting, energy-efficient LED fixtures. This powerful HID LED retrofit uses just 150 watts of power to emit 20,000 lumens of cool white light. It's designed to replace 400-watt MH bulbs and lasts at least twice as long, which reduces costly repairs, disposal fees, and the need for replacements. The LED retrofit lamp has an aluminum LED-cooling heat sink and shatterproof polycarbonate lens. An EX39 mogul screw base allows for easy installation in MH fixtures with EX39 or E39 sockets. A safety cable is included. Ballasts can be bypassed or removed. This bulb operates on 100-277 VAC. It's great for high-/low-bay lights, warehouses, factories, canopy lights, gymnasiums, and more.
