PHOTOBIO LED Grow Lights for Commercial Horticulture
PHOTOBIO is a commercial horticultural lighting brand produced by Sunlight Supply, one of the largest horticultural product distributors in North America. Their TX and MX LED bar array series are designed for commercial greenhouse and indoor production, providing verified photometric data, 0-10V dimming compatibility, and the component quality (Samsung or equivalent diodes, commercial-grade drivers) that commercial operations require. PHOTOBIO occupies the competitive commercial LED tier alongside Growers Choice and Iluminar -- delivering commercial-grade performance at competitive price points with the backing of Sunlight Supply's distribution and service infrastructure.
PHOTOBIO TX Series
The PHOTOBIO TX series are multi-bar LED arrays for primary canopy lighting, covering 4x4 to 5x5 ft flowering footprints at 2.7-3.0+ umol/joule efficiency. TX fixtures use Samsung LM301H diodes and are dimmable via 0-10V analog input for TrolMaster and compatible controller integration. Published PPFD maps are available for each TX model -- use these with our PPFD & Light Coverage Calculator to confirm coverage for your specific canopy dimensions.
PHOTOBIO MX Series
The PHOTOBIO MX series is designed for controlled environment agriculture (CEA) and greenhouse supplemental lighting applications, with specifications suited to overhead mounting in higher-clearance commercial facilities. For operations comparing PHOTOBIO against Gavita, Growers Choice, and Iluminar, PHOTOBIO's distribution through Sunlight Supply provides broad dealer availability and service access across North America. Commercial accounts available.
PHOTOBIO FAQ
How does PHOTOBIO compare to Gavita and Growers Choice?
All three are commercial-tier LED brands using Samsung LM301H or equivalent diodes at 2.7-3.0+ umol/joule efficiency. Gavita has the most established commercial track record, EL2 Master Controller ecosystem for large-facility management, and the widest service network globally. Growers Choice has strong pricing and the most grower community documentation. PHOTOBIO's primary advantage is its distribution through Sunlight Supply, the largest horticultural distributor in North America -- broad dealer availability and service access. For most commercial operations evaluating all three, photometric performance is comparable; the differentiators are price, controller ecosystem compatibility, and distributor/service infrastructure priorities.
What canopy size does a PHOTOBIO TX cover?
The PHOTOBIO TX series covers 4x4 to 5x5 ft flowering footprints depending on the specific model wattage. Published PPFD maps are available for each TX fixture at multiple hanging heights -- use these with our PPFD Calculator to confirm coverage for your exact canopy dimensions and target intensity (typically 900-1,100+ umol/m2/s for peak flowering). For commercial facility design with multiple PHOTOBIO fixtures, our commercial team can assist with layout planning -- call 888-815-9763.
Are PHOTOBIO lights compatible with TrolMaster?
Yes -- PHOTOBIO TX 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 light reduction, and remote intensity adjustment via the TrolMaster app. Connect the 0-10V dimming cable from each PHOTOBIO fixture to the Hydro-X's analog output channels for coordinated multi-fixture dimming control.
What warranty does PHOTOBIO offer?
PHOTOBIO TX and MX series fixtures carry a 5-year limited warranty covering manufacturing defects and LED failure. Warranty service is provided through Sunlight Supply's dealer network. For commercial installations where warranty service turnaround time affects production continuity, confirm replacement fixture availability through your local Sunlight Supply dealer before committing to a large installation. Our commercial team at Hydrobuilder can assist with warranty questions for PHOTOBIO fixtures purchased through us.
Is PHOTOBIO available for commercial volume orders?
Yes -- PHOTOBIO fixtures are available for commercial volume orders through Hydrobuilder's commercial accounts program. Commercial accounts provide dedicated pricing, priority order processing, and commercial support for facility builds and expansions.
