Kingbrite’s P55 480W is a rotatable six‑bar LED grow fixture built around Samsung LM301H EVO whites, enhanced by Osram 660 nm deep‑red and 730 nm far‑red diodes for a full, photosynthesis‑focused spectrum. It ships with a 0–10 V dimmable Inventronics 480 W driver and is designed for flexible canopy coverage in 1.2 × 1.2 m (4 × 4 ft) to 1.5 × 1.5 m (5 × 5 ft) spaces. Bars rotate to fine‑tune light spread and reduce hotspots over dense plantings. Two bar configurations are commonly offered—244 LEDs/bar (983 × 902 mm) or 183 LEDs/bar (890 × 902 mm)—to balance diode density and fixture size. The fixture is rated for 50,000 hours of service life and targets efficient, uniform PPFD across the tent.
