Phytonaut LED Grow Light 320 W

The Phytonaut 320 W is Zamnesia's own-brand LED, and unusually for a shop brand it publishes the numbers that matter: 927.64 µmol/s of PPF at 2.83 µmol/J, on Sanan and Osram chips with a balanced full-spectrum profile.

Cooling is passive, so it is silent and has no fan to fail, and the lifespan is given as ≥54,000 hours within a 0–40°C operating range. It is IP65 splash-resistant. The 120° distribution is aimed at even coverage rather than a bright centre, which is the right trade once a canopy fills a tent.

Dimming works two ways: a rotary knob on the driver, or 0 to 10 V external control from 10 to 100 percent — which is how it pairs with a controller. Hang it 45 to 90 cm over seedlings and 20 to 40 cm in flower.
