ASD Direct-lit Panels are a great economical choice for an easy direct replacement for recessed panel lighting. They are sold in pairs and are cULus listed and DLC approved. Once installed these panels have the look of a standard fluorescent fixture with a prismatic lens, but are only 1” thick. Our panels are reasonably priced, maintenance free and can significantly reduce your energy bills. Up to 20 dimmable panels can be linked to each master panel.
