LED Living Technology introduces the Tfive Swing Up LED retrofit kit for 4-foot linear high-bay fixtures containing T5HO, T8 and T12 lamps. Lightweight and easy to handle, the Tfive accommodates varying fixture sizes and maintains consistency in output and optics regardless of reflectors. The Tfive offers efficacies of 155lm/W to 174lm/W and lumen output of up to 60,000 lumens. The Tfive’s available correlated color temperatures (CCTs) include 3500K, 4000K and 5000K, and all models are DLC QPL Premium Listed. The Tfive also features controls options for 1-10V and wireless dimming as well as occupancy/daylighting sensors. Facilities retrofitting from T8 or T5HO lamps can expect a minimum of 58 percent energy savings with equivalent lumens.
