The 6 pack of 65 Watt Filament ED37 LED Light Bulbs offer superior lighting quality and value, providing a long-lasting, reliable light source for parking lots, wall packs, and other industrial installations. With a 5000K daylight color, these bulbs provide an instant start-up with no color shifting, surge protection up to 4000 volts, plus universal mounting positions. These super-bright bulbs produce 12,000 lumens of light. Their EX39 mogul base fits fixtures with E39 or EX39 sockets, and the voltage range is compatible with 120-277 volts. A ballast bypass energy-efficient replacement for 400-watt HID, with a smaller diameter and lighter weight, these ED37 bulbs are an excellent alternative to corn cob LEDs. ETL/CETL listed, FCC compliant, and RoHS certified, suitable for damp locations and enclosed fixtures – these are the perfect high-lumen lighting solution.
