Go All In with Grower’s Choice ROI-E900 Commercial-Grade LED for Higher Density, Better Potency, and Faster Growth

Get to Know the Grower's Choice ROI-E900 LED Grow Light

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

What's Included?

  • ROI-E900 LED System
  • Rope Ratchet

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
