Dial in the spectrum your plants want with the Tarantula Volcano Evo, a high-output, spectrum-tunable fixture built for under-canopy lighting and versatile enough for overhead use as well. This spectrum combination is exclusive to Grand Master, featuring three targeted channels:

• Warm White – 120W
• Cool White (18,000K) – 120W
• Far Red (730nm)– 15W

The Warm White channel delivers an HPS-style spectrum, producing that familiar orange, warm glow growers love from traditional HPS setups—while offering the world's most diverse spectrum range. With spectrum tuning, you can precisely hit targets between 20–60% red and 4–35% blue, allowing you to steer plant response across different growth stages and environments.

If you love the HPS look and plant response, this fixture is the upgrade path in the right direction.
