Illuminate 4’x5’ grow spaces with a powerful, efficient 1,000W LED delivering deep canopy penetration.

Meet the ROI-E900, the heavyweight champion of LED grow lights. Nicknamed “Fat Boy” for a reason, this XL 8-bar fixture delivers a massive 1,000W of supercharged photon output, blasting 4' x 5' grow spaces with Growers Choice’s proven 3K full-phase spectrum. Designed for commercial cultivators, it ensures deep canopy penetration, extended coverage, and superior light uniformity, making it the ultimate powerhouse for high-yield operations.

Is the ROI-E900 Energy-Efficient?

Absolutely. The ROI-E900 boasts an efficiency of 2.8–3.0 µmol/J, leaving HPS fixtures (1.3–2.1 µmol/J) in the dust. This means higher light output per watt, lower power bills, and bigger, denser yields. For maximum ROI in commercial flower rooms, Fat Boy reigns supreme.

Features

• Highly efficient: 2600 umol/s total output while using only 1050w (2.6 umol/j efficacy)
• Large coverage area: 4'x5' at maximum 6" above the canopy.
• Great spectrum: 3000k full-spectrum white plus 660nm deep red (Osram diodes)
• Dimmable: dim from 0 to 10v to save on power when full output is not needed
• Remote operation: control multiple lights with Grower's Choice Master Lighting controller (choose the add-on above)
• Great light distribution: multiple bar light configuration makes for a more even light distribution
• Fanless design: bar light design also means fans are not required to deal with heat
• Rated for commercial use: IP65 waterproof plus UL8800, UL1598, DLC and CE certification
