This Westinghouse ED37 bulb is built to replace old HID fixtures without swapping the fixture itself. The EX39 mogul base is the same connection used in metal halide and high-pressure sodium lamps, so it drops into existing high-bay lights, warehouse fixtures, and outdoor area lighting already fitted for that socket.
At 65 watts, it puts out 12,000 lumens, which Westinghouse rates as a 750-watt equivalent. That's a steep drop in energy draw for the same light output, which matters most in facilities running fixtures for long hours. The 5000K daylight color and 80 CRI give clean, neutral light suited to work areas where color accuracy isn't critical but visibility is. It's rated for 120-277 volts, covering both standard and commercial wiring, and is built for indoor or outdoor use. Rated life is 25,000 hours. Note it's not dimmable and carries no Energy Star, DLC, or smart-home features - this is a straightforward, high-output retrofit bulb.
