Backlit sign cabinets, refrigerated display cases, and outdoor cold-weather fluorescent housings run on T12 HO tubes with recessed double-contact ends. This 35-watt 24-inch tube fits R17d sockets and puts out 1,400 lumens at 6500K daylight for reliable brightness across the run.
The T12 diameter with recessed R17d contacts handles the mechanical demands of channel-letter and sign-cabinet applications, where standard bi-pin bases don't hold up. Universal operating position and a 9,000-hour rated life keep it practical for outdoor signage, walk-in coolers, and long linear runs.
