Kingbrite’s P55 320W is a rotatable barâstyle LED grow light built around Samsung LM301H EVO diodes supplemented with Osram 660 nm deepâred and 730 nm farâred for a balanced, fullâspectrum output. The 320 W fixture is sized for a 3×3 ft (≈90×90 cm) grow area, providing uniform canopy coverage in compact tents. The P55 uses four passiveâcooled light bars with 0–10 V dimming, suitable for both vegetative growth and flowering. Listings specify IP65 construction and a rated lifetime of about 50,000 hours. A retailer specification notes 1,024 LM301H EVO diodes distributed across four bars, plus red and farâred chips, with versions offered for 3×3 ft or 1×1 m tents. This configuration targets efficiency and even distribution in small indoor setups.
