TechBrite’s LED High Bay Retro provides a viable alternative to replacing existing linear fluorescent high bays. The LED High Bay Retro is popular in applications where existing fixtures are “piped” or hard-wired to the power source. It is one of TechBrite’s highest LPW solutions, boasting over 150 LPW in the highly efficient lumen packages, qualifying for DLC Premium. The standard 0-10v dimming allows for maximum control. The “C” and “D” packages allow an integral occupancy/ daylight sensor for even greater field adjustability. The LED High Bay Retro is the “plug and play” answer for difficult-to-replace fixtures, while offering maximum controllability.
