The McGill TL Series of HID industrial lighting fixtures deliver more than double the light output of comparably-priced incandescent models, while cutting annual operating costs by more than 50 percent. These UL-listed high-intensity discharge temporary fixtures yield more than 6 foot candles of illumination from a 20-foot mounting height, plus provide the protection of a plated-steel wire lamp guard for use in new construction projects, industrial sites and warehouses. Its die-cast aluminum ballast housing with powder-coat paint makes it suitable for damp jobsites such as tunnels, bridges and marinas.
