Outfit your warehouse, gymnasium, factory, or convention hall in energy efficiency with the GCP ELH6002 CFL high bay. Designed for high-wattage, self-ballasted CFLs up to 300 watts, the fixture is a great replacement for existing HID systems. Just wire the fixture to a 120 or 277 volt system, screw a Mogul (E39) base bulb into the socket, and you're ready to go! There's no need for a bulky external ballast. The 16-inch, spun aluminum anodized reflector combines high efficiency with extended lamp shielding and glare control for efficient illumination of any large area. Both ETL listed and RoHS compliant, the ELH6002 CFL high bay is backed by Global Consumer Products' 3-year warranty.
