From the supplier
Phytonaut LED Grow Light 480 W: Maximum Output with Controlled Coverage
The Zamnesia Phytonaut 480 W LED Grow Light is built for high-output indoor grows where consistency is just as important as power. It delivers a large volume of usable light while maintaining even distribution across the grow area. The result is fewer weak spots, fewer lighting adjustments, and a canopy that develops at a steady, uniform pace.
Phytonaut LED Grow Light 480 W: High-output full-spectrum lighting for larger grows
Equipped with Sanan + Osram LED chips, the Phytonaut 480 W runs a balanced full-spectrum designed for full-cycle cultivation. It supports strong vegetative growth and reliable flowering performance without unnecessary complexity.
Key output: 1415.33 µmol/s* PPF with an efficacy of 2.9 µmol/J*. This delivers a high level of photosynthetically active light while maintaining strong efficiency relative to power consumption.
Coverage: 120° light distribution for wide, even spread
The 120° beam angle pushes light outward across the grow space rather than concentrating it in a central hotspot. This helps maintain more uniform canopy development, particularly in larger setups where edge performance plays a critical role in overall results.
Passive cooling: Silent operation, ≥54,000-hour lifespan
Passive thermal management keeps the fixture completely silent and reduces long-term wear. With no fans, there are fewer moving parts and less maintenance required. The Phytonaut 480 W operates within a 0–40°C range and is rated for a lifespan of ≥54,000 hours.
Dimming: Manual levels for controlled intensity
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 settings suit young plants and early stages, while higher output supports dense, mature canopies with increased light demand.
Build quality: IP65 protection for humid environments
With an IP65 rating (splash-resistant), the Phytonaut 480 W is designed for humid tents and 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 480 W is well suited for:
- Growers managing larger indoor spaces who need high output with broad coverage
- Setups where even canopy development is a priority
- Anyone who values silent operation and low-maintenance design
- Growers upgrading to a powerful, efficient full-spectrum LED for full-cycle use
*Values may vary due to manufacturing tolerances and test conditions. Sticking with the same brand, the Pure LED Q320 Grow Light draws 320 W and builds on Samsung LMB281+ PRO and Honglitronics SMD3535 diodes, rather than the Sanan and Osram chips in this 480 W fixture.
