Lumatek Zeus Pro 300W 3.1 LED

Compact 3.1 µmol/J efficiency without the running costs

The Lumatek Zeus Pro 300W 3.1 is a full-spectrum LED fixture built around Samsung LM301H EVO and Osram 4.24 diodes, delivering 965 µmol/s PPF at up to 3.1 µmol/J efficacy from around 312W draw. Passive fanless cooling keeps it silent, and the IP65 build shrugs off the humidity and splashes of a working grow room — ideal for a 1.2 x 0.6m footprint.

Key Benefits

• 965 µmol/s PPF at up to 3.1 µmol/J for high output per watt
• Samsung LM301H EVO and Osram 4.24 diodes for genuine full-spectrum light across the whole cycle
• IP65-rated housing that stands up to humid grow room conditions
• Passive fanless cooling for completely silent running and fewer moving parts to fail
• Modular magnetic bars (3 x 100W) that swap out in seconds, with optional UV and far-red add-ons
• Onboard dimming 25–100% or control via the Lumatek Digital Panel Plus 2.0 and 0-10V controllers

Weak yields from inefficient lighting?

Older, lower-efficacy fixtures can't push enough usable PPF across a canopy without burning power. The Zeus Pro 300W 3.1 delivers strong photon output at 3.1 µmol/J over a compact 1.2 x 0.6m footprint, so you get the light your plants need without the electricity bill of a less efficient lamp.

How to Use

• Hang the fixture above the canopy, raising it during propagation and early veg
• Lower it gradually into flower to hit your target PPFD, watching leaf response
• Use the onboard dimmer to set output between 25% and 100%
• Connect to a Lumatek Digital Panel Plus 2.0 or 0-10V controller for automated scheduling and dimming
• Add optional UV or far-red magnetic bars to fine-tune spectrum by growth stage
