Grand Master LED Tarantula Torch 850W | 2-Channel Adjustable Spectrum | PPF 2134 µmol/s | IP66 | Folding Design | RJ14 Controller Ready | Inventronics Driver | 3 Year Warranty

The Grand Master LED (GML) Tarantula Torch 850W is a spectrum-tunable, commercial-grade grow light built for commercial production, vertical racks, medical gardens, and high-performance tents. With a unique 2-channel adjustable spectrum design, it lets you shift intensity between a more HPS/red-style channel and a more MH/blue-style channel, giving you flexible control across different plant stages and cultivation strategies.

Powered by LEDSTAR diodes (including white, 660nm red, and 450nm blue) and driven by an Inventronics driver, the Tarantula Torch delivers strong output with rugged reliability. It includes 12 preset spectrums (referenced in the manual) for easier tuning, while knob dimming and a standard RJ14 port make it compatible with external controllers and automated room control systems.

Built for demanding grow environments, it features an IP66 waterproof rating, a folding design for fast installation, and is backed by a 3-year warranty.
