INTRODUCING

QUANTUM PAR 450w LED Grow Light
4Season Quantum PAR 450W LED Grow Light – Pro-Grade Full Spectrum for Large Grow Spaces The 4Season Quantum PAR 450W is built for serious Australian growers chasing commercial-level results. Featuring the same next-gen EVO+ diode blend as its smaller brothers, this beast is packed with Samsung LM301H EVO, LM301H, 4Season 2835, and high-powered Osram deep/far-red diodes to drive maximum yield from seedling to harvest. Whether you’re running large tents or full-room grows, this 450W full-spectrum light floods your canopy with uniform PPFD and deep penetration—no hotspots, no weak zones, just reliable plant power.

IDEAL RESULTS

FOR INDOOR CULTIVATION

Built for performance, this light covers up to 120cm x 120cm for flowering and expands to 150cm x 150cm for vegetative growth. With diode efficacy reaching 3.14 μmol/J on the white spectrum and 3.8 μmol/J from the supplemental reds, every watt is efficiently converted into plant-usable light. A dense build featuring 960 diodes powered by a dedicated 4Seasons 450W driver ensures deep canopy penetration and even PPFD distribution across your entire grow area.
For control, the onboard 0–100% dimmer lets you easily adjust light output to suit any stage of plant growth. Cooling is handled silently via a large passive heatsink—no fans, no moving parts, just efficient, quiet operation. Compact and durable, the Quantum PAR 450W measures 69cm x 69cm, weighs 11kg, and is built to run for over 50,000 hours. Backed by full AUS Electrical Safety Certification and a 5-year Australian warranty, this fixture is designed for long-term, worry-free performance.
From commercial setups to serious home grows, the 4Season Quantum PAR 450W delivers powerful, full-spectrum light with plug-and-play simplicity and low energy use. Pair it with the 4Season Master Controller (sold separately) for advanced automation and control. Shipped fast from our Melbourne warehouse.
