Tarantula Volcano Red – Spectrum Tuning Under-Canopy Lighting

Take precise control of your under-canopy spectrum with the Tarantula Volcano Red, a high-output, spectrum-tunable fixture designed to drive strong lower-canopy performance while giving you the flexibility to fine-tune plant response.

This fixture is built around three controllable channels:
Red Channel (90% Deep Red) – 120W
Cool White (18,000K) – 120W
Far Red (730nm) – 15W 

With spectrum tuning, you can run any red level between 20% and 90% (at 120 watts) and adjust blue from 0% up to 35%, letting you tailor your mix for different cultivars, growth stages, and canopy density. The 15W Far Red channel is controlled independently, so you can add far red only when you want it—without changing your core spectrum.

Purpose-built for under-canopy use, the Volcano Red is a go-to option for growers who want a red-forward spectrum with adjustable blue and far red control in one streamlined fixture.
