Lumatek Zeus 300W Pro 3.1 — Precision LED Performance for 1.2×0.6m Grows

Built for cultivators who need Lumatek’s 3.1-generation performance in a fixture precisely matched to a 1.2 × 0.6m footprint, the Zeus 300W Pro 3.1 delivers an outstanding 965 μmol/s PPF at 3.1 μmol/J fixture efficacy. Powered by Samsung LM301H EVO and Osram 4.24 top-bin diodes, with Lumatek’s magnetic modular 3-bar design, IP65 clear glue protection, and optional UV & Far-Red bar add-ons — this is the most versatile compact LED in the Zeus Pro range.

Why Growers Choose the Zeus 300W Pro 3.1

• ✅ 965 μmol/s PPF at 3.1 μmol/J — outstanding efficacy for a compact fixture; intense output with minimal energy consumption
• ✅ Samsung LM301H EVO + Osram 4.24 diodes — latest-generation top-bin diodes for maximum output, consistency, and long-term light maintenance
• ✅ Magnetic modular 3-bar design — easy installation, maintenance, and customisation; bars click in and out without tools
• ✅ Optional UV & Far-Red LED bar add-ons — expand the spectrum curve for targeted biological responses at any growth stage
• ✅ Clear glue protection on all bars — 99% light transmittance, IP65 waterproofing, corrosion resistance, extended diode lifetime
• ✅ IP65 rated — reliable in humid, high-demand grow environments; clean bars with wet cotton for basic maintenance
• ✅ Rectangular 1.2×0.6m footprint — engineered for single benches, multi-layer cultivation systems, and low-ceiling rooms
• ✅ Fully dimmable: OFF / 25% / 50% / 75% / 100% — 0–10V dimmer included; adapts to every growth stage from propagation to flower
• ✅ Lumatek Control Panel Plus 2.0 compatible — 1% increment dimming, Sunrise/Sunset mode, temperature safety control, up to 100 fixtures per controller
• ✅ Passive thermal management — 3 low-powered bars reduce heat output and enhance uniformity vs fewer higher-powered bars
• ✅ 5-year warranty — Lumatek’s strongest warranty; backed by Growers Depot AU

Magnetic Modular Design — Lumatek’s Pioneer Innovation

Lumatek pioneered the magnetic modular LED bar design — and the Zeus 300W Pro 3.1 brings it to the compact format. Three low-powered, high-efficacy LED bars click into the frame magnetically, with no tools required for installation, removal, or servicing. The low-powered bar configuration reduces LED operating temperature compared to fewer, higher-powered bars — increasing output stability, enhancing light uniformity across the 1.2×0.6m footprint, and prolonging component lifespan across the fixture’s 60,000-hour rated life.

Optional UV & Far-Red Add-On Bars — Expand Your Spectrum

The Zeus 300W Pro 3.1 is the only compact Zeus fixture with the ability to add supplemental UV and Far-Red LED bars to the existing frame. UV stimulates trichome and resin production through stress response. Far-Red triggers the Emerson Enhancement Effect and accelerates phytochrome-mediated flowering signals. These add-ons let you dial in the precise spectrum balance for every phase of your plant’s life cycle — without replacing the fixture.

Samsung LM301H EVO + Osram 4.24 — Next-Generation Diodes

The Zeus 300W Pro 3.1 uses the same diode combination as the full-size Zeus 600W Pro 3.1: Samsung LM301H EVO for broad-spectrum white output and Osram 4.24 for deep red. The clear glue protection layer achieves 99% light transmittance — meaning virtually no output is lost to the protective coating — while simultaneously delivering IP65 ingress protection and corrosion resistance. Clean the bars with wet cotton for basic maintenance.

Precision Control — From Basic Dimming to Full Automation

The Zeus 300W Pro 3.1 includes a 0–10V dimmer for 5-step manual control out of the box. For full room automation, pair with the Lumatek Control Panel Plus 2.0 for 1% increment dimming, Sunrise/Sunset simulation, temperature-triggered auto-dim and shutdown, and control of up to 100 fixtures per controller. Compatible with any universal 0–10V controller; RJ-to-0–10V adaptor available for RJ-port systems.
