Progrow 2100 HB

Grow Light Science’s PROGROW 2100 HB refers to the 2100-class PROGROW fixture used as a high-output, array-based top light. Retail listings specify 791 W input power and about 2,101 µmol/s PPF in a low-profile, multi-bar chassis measuring 44.7 x 43.7 x 1.9 inches and weighing roughly 23.2 lb. The brand’s commercial pages show multi‑fixture PAR mapping for the PG 2100 over an 8 x 12 ft section at 18 inches, averaging ~1,411 µmol/m²/s, and note ETL UL 8800 certification, DLC listing, 0–10 V control compatibility, and IP65 construction. This model is typically deployed in arrays for uniform canopy intensity and can integrate with GLS dimmers/controllers.
