The Gorilla Xi420 is a 420W full spectrum LED grow light engineered for 2x4 to 3x4 tent footprints with tri-channel Main, Far Red, and UV control through the built-in GXi app.

Gorilla Xi420 full spectrum LED grow light built for 2x4 and 3x4 grows
The Gorilla Xi420 is a professional-grade full spectrum LED grow light engineered for growers running a 2x4, 3x4, or narrow-room footprint. Its tri-channel spectrum runs independent Main, Far Red, and UV channels through the built-in GXi app, so a single Xi420 drives seedling, veg, and flower across a full two-zone canopy without swapping fixtures. 1055 PPF at 2.7 umol per joule efficacy pulls just 3.50A at 120V for flower-grade PPFD coverage.
Heavy-duty features of the Xi420 LED grow light
Independent Main, Far Red, and UV channels for stage-specific tuning that single-channel fixtures cannot match.
Top-of-class photon output for the 420W segment. Delivers 600 to 900 PPFD across a full 3x4 canopy.
Total fixture efficacy hits flower-grade PPFD without overspending on power. 3.50A at 120V or 1.75A at 240V.
Paired with an industry-leading Inventronics driver for long-term spectrum stability and low failure rates.
Spectrum Mastery, Sunrise and Sunset ramps, schedules, and environmental protection. Built-in wireless, no hub needed.
Extruded aluminum body dissipates heat passively. Remote driver accessory supports outside-tent mounting for extra cooling.

- Grow in a 2x4 or 3x4 tent, closet, or narrow room
- Want full spectrum with independent Far Red and UV control
- Run 3 to 6 plants with training or a perpetual harvest layout
- Want app control and built-in wireless, no external controller
- Need premium diodes and a 3-year warranty on a 420W fixture
