ROI-E420 LED
Grow Lights420W
The ROI-E420 is the small fixture in the Growers Choice ROI line: 420W in, 1090 μmol/s of PPF, 2.6 μmol/J, GC-3K Full Phase spectrum over a 120 degree spread.
Growers Choice puts it at 4ft x 4ft in veg and 3.5ft x 3.5ft in flower, hung at least 6" (15.2cm) above the canopy. Cooling is Passive — no fan to fail or add noise — and at 35.3 by 34.6 inches and 19.4 lbs. it will physically fit a 4x4 tent, which the bigger ROI fixtures will not. It runs on 120, 208, 240 or 277 Volt, pulling 4.0 Amps at 120V, and dims over 0 - 10 Volt.
