If you are looking to convert to the LED technology available for your high bays but aren’t quite interested in replacing all your existing fixtures, then a retrofit kit can work to your advantage. The shoebox retrofit kit is designed to replace a less efficient bulb in a preexisting light fixture with a more efficient LED bulb and driver. These kits are ideal for replacing metal halide (MH), high pressure sodium (HPS), and mercury lamps. In order to choose the correct retrofit kit it is important to know the type of high bay lighting you have already. The color (2700k – 4100k), lumens, and wattage will be important specs to know. Learn more about retrofitting your shoebox lighting fixture here!
