== Description ==

Outshine the competition using PLT SN-VP-E39-400W-4000-G1 LED high bay retrofit lamps in your large retail locations. These 400-watt equal metal halide replacements provide superior light quality and huge energy savings without the cost of converting your current fixtures or ballasts. The innovative LED is easy to install, simply remove the current metal halide bulb, screw in the new lamp, attach the lamp safety lanyard to a vent hole near the base of fixture, and enjoy the beauty of energy-efficient LED lighting!

*Applicable locations include gymnasiums, warehouses, large retail stores, and high ceiling downlight
*Runs on the same pulse- and probe-start magnetic ballasts as traditional metal halide lamps
*Use in dry, interior conditions only; not for condensing humidities or damp locations
*Lasts 5 times longer than metal halide lamps; 50,000 life hours
*Works as a vertical downlight in open or vented fixtures
*Has a 4000K, cool white illumination
*Compatible with motion sensors
*CRI of above 70
