Built for commercial growers across the US and Canada, The Under Canopy Light for the North American market uses a dual side emission design to reach the bud sites your top light simply can't cover. Clients running it report a consistent 20 to 25 % increase in yield - and it's engineered specifically around what North American commercial grow rooms actually need: strong flowering performance, energy efficiency, and consistent output across large-scale operations.
Key Features and Advantages
Built with large Samsung LED diodes for higher photon efficacy - more usable light output per watt drawn. As a high efficacy Under Canopy Light option, that means lower energy cost per square foot of canopy, without giving up output, and across dozens or hundreds of units, that difference adds up directly on the power bill.
Dual Side Emission Design
Light comes from both sides of the fixture at once, covering two planes of the canopy interior in a single pass - ideal for rows trained or trellised on both sides, like SCROG setups and trellis netting systems, so both faces of the plant get direct light instead of one lit side and one shaded side.
Weighted heavily toward red light, with blue in a supporting role - red-dominant spectrums drive flower development during bloom, directing energy toward bud density and finish rather than stretch, which is exactly what the lower canopy needs.
Multiple Sizes to Fit Every Row
Available in 150W under canopy light, 180W under canopy light, and 250W under canopy light, across 4ft, 6ft, and 8ft lengths - so growers can match fixture length and wattage to their actual row width and canopy density instead of forcing one size across a room it doesn't fit.
Why Under Canopy Light Is a Best Seller in North America
Commercial cultivation in North America is running on tighter margins than it used to - rising operating costs, competitive wholesale pricing, and pressure to get more usable flower out of every square foot of canopy. Under canopy light has become one of the fastest ways to answer that pressure, because it doesn't require rebuilding a room. Growers already running a solid top light setup can add fixtures into the existing canopy and start seeing results the same cycle, without new electrical infrastructure or a full room redesign.
That fast, low disruption payoff - combined with the shift from loose, low value lower canopy flower to dense, sellable bud - is why this best selling under canopy light has moved from a niche add-on to a standard part of commercial grow room design across the US and Canada.
About JT Grow Light
As an under canopy light manufacturer, JT Grow Light has spent 10 years focused on one thing: building efficient, intelligent, and environmentally sound LED lighting solutions for the global agriculture and horticulture market. Our fixtures and technical support now reach tens of thousands of professional growers across dozens of countries, including the United States, Canada, Brazil, Argentina, Russia, the Netherlands, the UK, South Korea, Japan, Vietnam, and India.
Our clients span a wide range of controlled environment and greenhouse cultivation - commercial cannabis, vegetables and fruiting crops, flowers, medicinal plants, corn and rice cultivation, nursery and tissue culture operations, and research institutions. We've earned dozens of invention patents and software copyrights along the way, and we continue to invest heavily in R&D, with current work focused on IoT-based control systems for LED horticultural lighting - with new products from that research on the way.
FAQ
Q: Is this light suitable for large scale North American commercial grow operations?
A: Yes - it's built with commercial scale in mind, from the wattage range to daisy chain controller compatibility, so it scales from a single room to a full facility without changing fixture types.
Q: What makes the spectrum different from standard under canopy lights?
A: The spectrum is weighted more heavily toward red output relative to blue, which is tuned specifically for flowering performance rather than general purpose or vegetative growth.
Q: How much can I save on energy costs with high efficacy Samsung chips?
A: Exact savings depend on your room size and current fixture wattage, but higher efficacy chips mean more light output per watt drawn, which lowers energy cost per square foot of canopy compared to lower efficacy alternatives at the same wattage.
Q: What sizes and wattages are available for different row spacing?
A: 150W, 180W, and 250W options across 4ft, 6ft, and 8ft lengths - narrower or tighter rows typically pair with lower wattage, while wider commercial rows run higher wattage for full coverage.
