GLT TR22 2×2 LED Troffer — 15/25/36/40W Selectable — White

The GLT TR22 is a 2×2 recessed LED troffer designed for commercial grid ceiling applications including offices, healthcare, education, and retail. Wattage is field-selectable between 15W, 25W, 36W, and 40W, and color temperature is field-selectable between 3000K, 3500K, 4000K, and 5000K via an onboard switch — no tools required. At peak output, the fixture delivers 5,600 lumens at 140 lm/W and supports 0-10V dimming down to 10%. The fixture operates on 100–277VAC, is UL Listed for damp locations, and is DLC Listed, qualifying for utility rebate programs. At its maximum 40W setting it replaces conventional 2-lamp F32T8 fluorescent troffer fixtures.
