The Kingbrite W55 Single Bar L1100 is a versatile, high-performance LED grow bar from Shenzhen Kingbrite Lighting’s W55 lineup. Stretching roughly 1.1 meters in length, this bar operates at a maximum of ~140 W (PCBA only), though full 600 W configurations are possible in multi-bar setups. It utilizes premium Samsung LM281B+ Pro or LM301H diodes paired with CREE XP‑E2 660 nm & 730 nm red and LG UV LEDs, delivering a full spectrum for optimal plant photosynthesis. Typical PPFD values in the canopy range between 150–700 µmol/m²·s, depending on configuration and mounting height. 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.
