The Kingbrite X55 Bar 480 W is a powerful and refined LED grow light system designed to deliver commercial-level performance in medium to large indoor grow spaces, such as 4 x 4 ft tents or compact rooms. This bar-array fixtures draws full 480 W using a blend of Samsung LM301H and LM281B+ Pro diodes, enhanced with 660 nm red, deep-red, and UV/IR chips to create a full-spectrum output aimed at optimized plant growth throughout the entire life cycle. Thanks to its high-efficiency diode selection, the fixture offers an impressive efficacy of ~2.5–2.7 µmol/J, delivering consistent PPFD readings between 150–250 µmol/m²·s, or up to 400–700 µmol/m²·s depending on placement and configuration. Kingbrite’s lighting setups are highly performant and if you want to explore more of their system, don’t hesitate to take a look at the QB288 240W LM301B Epistar 660nm or Kingbrite X55 Bar 320w configurations.
