Growers Choice LED Grow Lights -- ROI-E Series
Growers Choice is one of the most widely adopted LED grow light brands in North American commercial indoor production, best known for the ROI-E series of bar array fixtures. Their focus is straightforward: build efficient, reliable commercial LED fixtures with published photometric data, competitive pricing, and the customer support infrastructure that commercial growers require. The ROI-E series covers the 420W to 1000W class range with documented efficiency ratings of 2.7-3.0+ umol/joule -- placing them in the top tier of commercial LED performance alongside Gavita, Faven, and ThinkGrow.
Growers Choice ROI-E Series
The ROI-E line is Growers Choice's primary commercial LED offering. The ROI-E420 (420W) covers a 4x4 to 4x5 ft flowering canopy. The ROI-E680 (680W) covers 4x5 to 5x5 ft. The ROI-E720 (720W) -- arguably their most popular model -- is designed for 5x5 ft canopy coverage at 1,500-2,000+ umol/m2/s PPFD, and has become one of the most frequently referenced commercial LED fixtures in the grower community due to its combination of output, efficiency, and price point. All ROI-E fixtures use Samsung LM301H diodes and Inventronics drivers, are dimmable via 0-10V analog input for TrolMaster and compatible controller integration, and carry a 5-year warranty. Use our PPFD & Light Coverage Calculator with Growers Choice's published PPFD maps to confirm canopy coverage for your specific setup.

Growers Choice FAQ
What is the Growers Choice ROI-E720 and why is it so popular?
The Growers Choice ROI-E720 is a 720W LED bar array designed for 5x5 ft flowering canopy coverage, delivering approximately 2,016 umol/s of total photon output at 2.8+ umol/joule efficiency. It hits a combination of output, efficiency, price, and canopy coverage that makes it one of the most frequently cited commercial LED fixtures in the grower community. For growers running 5x5 ft flowering footprints, the ROI-E720 provides competitive PPFD (1,000-1,200+ umol/m2/s at standard hanging height) and 5-year warranty coverage at a price point lower than equivalent Gavita fixtures -- making it a compelling commercial value choice.
How does Growers Choice compare to Gavita?
Both are top-tier commercial LED brands with similar efficiency ratings (2.7-3.0+ umol/joule) and Samsung LM301H diodes. Growers Choice fixtures are typically priced lower than equivalent Gavita models with comparable photometric output. Gavita's primary advantages are the EL2 Master Controller ecosystem (managing up to 80 fixtures from one controller), the longest-established commercial service infrastructure in the market, and broader dealer and service network globally. For commercial operations already using Gavita's EL2 control system, fixture compatibility is a reason to stay within the Gavita ecosystem. For new builds evaluating both, Growers Choice delivers comparable photometric performance at lower upfront cost.
What warranty do Growers Choice lights carry?
Growers Choice ROI-E series fixtures carry a 5-year limited warranty covering manufacturing defects and LED failure. The warranty is serviced through Growers Choice directly -- contact information and warranty claim procedures are in the product documentation. For commercial operations where warranty service turnaround time affects production, confirm your specific warranty terms and replacement fixture availability before committing to a large installation. Hydrobuilder's commercial team can assist with warranty questions and support for Growers Choice fixtures -- call 888-815-9763.
Can Growers Choice lights be controlled with TrolMaster?
Yes -- Growers Choice ROI-E fixtures accept 0-10V analog dimming input, which is compatible with TrolMaster Hydro-X Pro's 0-10V analog output. This enables automated dimming schedules, temperature-triggered dimming (reducing output when canopy temperature exceeds setpoint), and remote light adjustment via the TrolMaster app. For facilities running both Growers Choice and TrolMaster, connect the 0-10V dimming cable from each fixture to the Hydro-X's analog output -- the controller manages all fixture dimming simultaneously from a single setpoint. Growers Choice's 0-10V input handles fixtures from 0% (off) to 100% output across the full dimming range.
