Outfit your construction site or temporary installation in energy efficiency with the GCP ELH6003 CFL temporary 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 12-inch, nickel-plated, rust-resistant cage both protects the lamp, illuminates any large area, and comes with a hook for better handling. Both ETL listed and RoHS compliant, the ELH6003 CFL temporary high bay is backed by Global Consumer Products' 3-year warranty.
