What the Growers Choice ROI-F720 Changes
Same 720 watts, different engine room. The F720 runs a single driver where the E720 splits the load, and that simplification is what brings the cost down. Output went up rather than down. This fixture puts out 2,160 umol/s at 3.0 umol/J, against roughly 1,870 and 2.6 on the E720. Spectrum is unchanged Full Phase 3K. The panel measures 42.4 x 41.3 in and weighs 14.33 lbs.
Sizing and Wiring a 720w LED Grow Light
Footprint first. Growers Choice guides the 720 platform at 5 x 5 ft in veg and 4 x 4 ft in flower where you want high intensity. A 720w led grow light at this output belongs in a room you control. Growers Choice asks for CO2 supplementation at this intensity, because light a plant cannot process becomes wasted power and heat. Wiring is the other half. This is hardwire only across 208 to 277V, with no cord and no plug, so an electrician terminates it. Draw is 3.4A at 208V, 3.0A at 240V and 2.6A at 277V, which is what you size the circuit against. Dimming is 0 to 10V, so it lands on a standard lighting controller. Rated life is L90 at 50,000 hours, meaning ninety percent of original output at that mark. Warranty is one year from the manufacturer.
Key Features
- 2,160 umol/s at 3.0 umol/J: Against roughly 1,870 and 2.6 on the E720. More light from the same 720 watts.
- One driver, not two: The simplification that brings the price down without costing output.
- Hardwire, 208 to 277V: No cord and no plug. 3.4A at 208V, 3.0A at 240V, 2.6A at 277V.
- 0 to 10V dimming: It lands on a standard lighting controller with no adapter in between.
- 5 x 5 ft veg, 4 x 4 ft flower: Platform guidance. At this intensity Growers Choice asks for CO2.
- 42.4 x 41.3 in, 14.33 lbs: A thin panel at roughly 2 in deep, rated L90 to 50,000 hours.
