Grow Lights680W
The ROI-E680S is the updated 680W fixture in the Growers Choice ROI line. It is listed at 1770 μmol/s and 2.6 μmol/J on the GC-3K Full Phase spectrum — the same power as the ROI-E680 it follows, with more photons out of it.
Coverage is given as 6' x 6' in veg and 5' x 5' in flower. The fixture is 46.5 by 42 inches, 3.2 deep and 29 lbs, rated IP65, wired for 120/208/240/277 Volt, and dimmed over 0 - 10 Volt from an external controller.
Power factor is above 90% and rated life is L90 past 54,000 hrs, behind a 5 Years Standard Warranty. Between this and the ROI-E680, the S is the one worth paying for — identical draw, more light.
