Growers Choice ROI-E900 LED Grow Light | 2,340 µmol/s, 8 Bars, 4x5 ft

Growers Choice ROI-E900 Output, Power and Build This 8-bar fixture is rated at 2,340 µmol/s in standard mode and 2,600 µmol/s in boost. Efficacy is 2.6 µmol/J, and maximum input is 1,050W. The driver autosenses 110–277V, drawing 8.9A at 120V, 5.0A at 208V, 4.5A at 240V and 3.8A at 277V. It ships with a NEMA 6-15P plug and a 5-15P adapter for 120V circuits. The spectrum is GC-3KF, a 3000K full-phase white with CRI above 86, spread across 2,800 diodes. That lets one fixture run from veg to harvest. The frame measures 46.9 x 59.5 x 3.2 in and weighs 55 lb. Cooling is passive, and the fixture is IP65 rated for -20 to 45°C. It carries UL 1598, UL 8800 and DLC listings. The diodes are rated to L90 at 54,000 hours, with a 5-year warranty on the fixture. Running a Commercial LED Grow Light Over a 4x5 Table A commercial led grow light this size fits long flower tables better than a square fixture. The rectangular frame matches a 4x5 table and stretches to 5x5 ft when hung higher. It can sit as close as six inches over the canopy, which helps in rooms with little headroom. Center plants tend to finish heavier than the corners, so rotate plants or fill corners with shorter cultivars if uniformity matters. The onboard knob dims from 10 to 100 percent, and boost mode adds output late in flower. The GC Master Controller, sold separately, links fixtures across a room for schedules and sunrise ramps. Start around half power in veg and raise it as the canopy fills in. Watch the tops closely at full boost, since bleaching shows up there first. Leave open air around the frame so the passive heat sinks can shed heat. For a 3x3 or 4x4 tent, a smaller fixture wastes less light on the walls. Key Features 2,340 µmol/s standard, 2,600 in boost: Enough output for a dense 4x5 flower canopy. 2.6 µmol/J: Efficient full-phase output from 2,800 diodes. GC-3KF 3000K full phase: One spectrum from veg to harvest, CRI above 86. Autosensing 110–277V: Ships with a 6-15P plug and 5-15P adapter. 10–100% dimming: Onboard knob or GC Master Controller over 0–10V. IP65, passive cooling: No fans, sealed for humid flower rooms, 5-year warranty.
