The BLS-PG-SQ is a cost-effective, energy-efficient LED luminaire for surface-mount applications. The thin and lightweight design and excellent heat dissipation of the housing extends its life. A precision-engineered optical lens reduces glare, improves optical performance, and provides comfortable illumination. The BLS-PG-SQ comes with an external quick-mount plate for standard J-BOX mounting, and is also compatible with 3/4″ pendant fixtures, with 1/2″ knock-out holes reserved on four sides, suitable for surface conduit wiring installation. The BLS-PG-SQ also supports four lumen packages (100%, 80%, 60%, 40%); and three CCTs (3000K, 4000K, 5000K).
