The Apollo series linear high bay fixtures offer tremendous efficacy levels above 130 lm/W, with outputs from 11,100 to 46,300 lumens. These fixtures are ideal for replacing one-to-one conventional HID and T8 or T5 fluorescent fixtures. Such high lumen outputs allow them to be mounted from ceilings ranging 15ft to 45ft. They are perfect for any warehouse or factory. Bi-level motion sensors, photocells, and EMs can be installed onto the product domestically to speed up production timelines.
