Description
Gorilla 720W LED GEN-III Grow Light
The Gorilla 720W LED GEN-III is a powerful, full-spectrum LED grow light designed to provide strong, even light distribution across grow spaces of up to 1.5m x 1.5m. Delivering an impressive 1944 µmol/s PPF with an efficiency of 2.7 µmol/J, it offers plenty of usable light for growers looking for high output without moving into the premium end of the LED market.
High-Output Full-Spectrum Lighting
Running at 720 watts, the Gorilla GEN-III uses six LED light bars to spread light evenly across the growing area. The bar-style layout helps reduce concentrated hot spots and provides more consistent coverage from the centre of the canopy to the edges.
Its full-spectrum output makes the GEN-III suitable for use throughout the growing cycle, providing plants with the light they need during both vegetative growth and flowering.
1944 µmol/s PPF & 2.7 µmol/J Efficiency
With a total photosynthetic photon flux of 1944 µmol/s and system efficiency of 2.7 µmol/J, the Gorilla 720W GEN-III converts its 720W power draw into a high level of usable photosynthetic light.
This combination of output and efficiency makes it a practical option for growers upgrading from older lighting technology or looking for an affordable high-output LED fixture.
Designed for 1.5m x 1.5m Grow Spaces
The six-bar configuration is designed to provide effective coverage across areas of approximately 1.5m x 1.5m, making the GEN-III well suited to larger grow tents and dedicated indoor growing spaces.
The open-bar construction also allows air to move freely around the fixture, while the relatively even distribution of LEDs helps spread the lighting load across the canopy.
Built-In Dimming & External Controller Compatibility
Lighting output can be adjusted directly from the fixture using the onboard dimmer, with settings for 25%, 50%, 75% and 100% output.
For growers running automated or centrally controlled grow rooms, the GEN-III also supports 0–10V external control, allowing the fixture to be integrated with compatible lighting controllers.
Being able to reduce output is particularly useful when plants are young, when less light is required, or when environmental conditions mean that running the fixture at full power isn't necessary.
Foldable 6-Bar Design
The GEN-III features a foldable frame, making the fixture easier to transport, store and install. Once opened, its six LED bars create a wide footprint for consistent light distribution over the growing area.
The driver is integrated into the fixture, helping keep installation straightforward without requiring a separate remote driver mounting position.
Built for Long-Term Use
With a rated lifespan of approximately 50,000 hours, the Gorilla GEN-III is designed to provide dependable lighting over many growing cycles.
It's backed by a 2-year manufacturer's warranty, providing additional reassurance for growers looking for a capable LED fixture at an accessible price point.

How to use
Unfold the frame, hang it over the canopy and plug it in: the driver is built in. Turn it down to 25% or 50% for young plants and raise it as they grow. With a lighting controller, connect it by the 0-10V port.
For matching a light to a tent, see LED grow light wattage by tent size.
Questions
What size tent is the Gorilla 720W for?
Up to 1.5 x 1.5 m. In a smaller tent, such as 1.2 x 1.2 m, use the dimmer.
Can it be dimmed?
Yes. The dimmer on the fixture has 25%, 50%, 75% and 100% settings, and it accepts 0-10V control from a compatible lighting controller.
Does it need a separate ballast or driver?
No. The driver is integrated into the fixture.
Growers’ guides
- LED Grow Light Wattage by Tent Size (and LED vs HPS)How many watts of LED a tent needs: 300-500 W/m² in flower, a table by tent size, the Maxibright, Gorilla and Adjusta-Watt fixtures that fit, and LED vs HPS.
- LED or HPS? Why the Best Growers Use BothTom's view from twenty years in the shop: run LED as the main light and add a dimmable HPS, metal halide or CMH for flowering weeks 3-7 for a better finish.
