The Kingbrite X55 Bar 650 W is a high-output LED bar light engineered for serious indoor gardening, perfectly suited to grow spaces in the 4 × 4 ft to 5 × 5 ft range. With eight bars packed into a modular frame, it delivers a full 650 W of true power and achieves impressive efficacy of around 2.75 µmol/J, making it extremely energy-efficient and well suited as a replacement for HID systems. The lighting array combines premium Samsung LM281B (or LM301H) diodes alongside supplemental 660 nm red, 730 nm deep-red, and UV/IR chips, creating a balanced full-spectrum output that supports every stage of plant development. Built with commercial-grade durability in mind, the fixture features an aluminum heat-sink housing and passive cooling design ensuring silent operation and long-term reliability. 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.
