ThinkGrow’s Model-I is a 720 W, IP66-rated LED fixture for single-level rooms and greenhouses. It delivers 1,829 μmol/s at 2.54 μmol/J and uses Samsung LM301B white diodes with supplemental UV and an independent far-red channel (far-red control via an external TrolMaster Hydro-X controller). The compact V-shaped housing integrates the driver, supports daisy-chain control, and autosenses 100–277 V. Typical coverage is up to 5×5 ft in veg and about 4×4 ft for flowering. L90 lifetime is rated over 54,000 hours. The fixture measures 45.24 × 4.36 × 6.46 in and weighs about 22.33 lb (≈10.13 kg). The design promotes uniform canopy intensity and closer mounting heights while maintaining even distribution across commercial benches.
