Phytonaut LED Grow Light 320 W: High Output with Even Canopy Coverage
The Zamnesia Phytonaut 320 W LED Grow Light is designed for growers who need more output without sacrificing control. It delivers a high volume of usable light while maintaining balanced distribution, helping the canopy develop evenly and keeping the grow easier to manage. This is a fixture suited to larger plant counts and longer cycles, without requiring constant adjustments.
Phytonaut LED Grow Light 320 W: Efficient high output for full-cycle indoor growing
Built with Sanan + Osram LED chips and a balanced full-spectrum profile, the Phytonaut 320 W is engineered for full-cycle cultivation. It supports strong vegetative growth and reliable flowering performance, focusing on steady, repeatable results rather than extreme centre intensity.
Key output: 927.64 µmol/s* PPF with an efficacy of 2.83 µmol/J*. The high PPF increases the amount of photosynthetically active light reaching the canopy, while strong efficacy ensures that output remains efficient at the wall.
Coverage: 120° light distribution for broad, practical spread
A 120° distribution angle spreads light evenly across the grow area instead of concentrating it in one hotspot. As grow spaces scale up, edge performance becomes critical. This wide spread helps reduce shadowing and supports more uniform canopy development, without forcing you to design the entire layout around the centre of the fixture.
Passive cooling: Silent operation, ≥54,000-hour lifespan
The Phytonaut 320 W uses passive thermal management, eliminating the need for fans. This keeps operation silent and reduces potential failure points over time. It operates within a 0–40°C range and is rated for a lifespan of ≥54,000 hours.
Dimming: Manual levels for stage-based control
Continuous manual dimming via the rotary knob on the driver, from OFF to full power. Also supports 0 to 10 V external control (10 to 100 percent) for use with the Zamnesia Grow Environment Controller and other compatible 0 to 10 V dimming systems. Lower output can be used for early growth or smaller plants, with intensity increased as the canopy thickens and light demand rises.
Build: IP65 protection for humid grow environments
An IP65 waterproof rating (splash-resistant) helps protect the fixture in humid indoor grow rooms.
Mounting height : The correct canopy distance
Seedling / clone 45 to 90 cm, vegetative 30 to 60 cm, flowering 20 to 40 cm. Increase the height if leaves curl or bleach (light too close), decrease the height if growth is stretchy (light too far).
Who is this light for?
The Phytonaut 320 W is well suited to:
- Growers who want higher output while keeping canopy management simple
- Indoor gardens where broad coverage reduces weak edges and shadowing
- Anyone who values silent, low-maintenance operation with passive cooling
- Growers upgrading from smaller fixtures and looking for more output headroom
*Values may vary due to manufacturing tolerances and test conditions. Bigger rooms tend to call for the Phytonaut LED Grow Light 480 W, which delivers 1415.33 micromol/s at 2.9 micromol/J where this one manages 927.64 micromol/s at 2.83 micromol/J. Sizes below and above are listed in our LED grow light selection.
