The Kingbrite W55 Single Bar L840 is a high-performance LED grow light bar extending roughly 840 mm, designed to deliver full-spectrum horticultural lighting in a compact module. Drawing around ~120–140 W, it harnesses premium Samsung LM301H diodes supplemented by red (660 nm deep red) and UV chips, producing an impressive efficacy rated up to 2.8 µmol/J. This spectral mix ensures healthy vegetative development and dense flowering within small-to-medium grow spaces. Featuring a robust aluminum housing with integrated heat-sink and powered by a quality MeanWell driver, the L840 offers reliable passive cooling and a long lifespan. It accepts wide-voltage input (AC 85–265 V), includes dimming support for flexible light control, and carries CE/RoHS certifications. 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.
