The Grow Light Science PROGROW 2100 is a commercial, full‑cycle LED top‑lighting fixture designed for arrayed use in indoor cannabis cultivation. It draws 791 W and outputs about 2,100 µmol/s of PPF, with published efficacy up to 2.8 µmol/J. The multi‑bar chassis is ETL certified to UL 8800, DLC listed, and rated IP65 for wet locations. Control options include onboard dimming via RJ12 and compatibility with GLS dimmers and the PROGROW Command Controller. The fixture measures 44.7 × 43.7 × 1.9 inches and weighs approximately 23.2 lb. Brand materials illustrate multi‑light uniformity; for example, six adjacent PG 2100 units at 18 inches over an 8 × 12 ft section average ~1,411 µmol/m2/s PPFD. Single‑unit tent footprint is not specified by the manufacturer.
