The Kingbrite P55 is a 240W full-spectrum LED bar-style grow light built around Samsung's LM281B diodes, aimed at serious indoor cultivation rather than a basic hobbyist panel. Four slim light bars carry 792 LEDs in total: 168 Samsung LM281B diodes per bar provide the core full-spectrum white light, supplemented on each bar by 24x Epistar 660nm deep-red, 3x 730nm infrared, and 3x 395nm UV diodes to support flowering and secondary metabolite production. Rated efficacy is around 2.4 µmol/J with roughly 37,400 lumens equivalent output (CRI 80), giving even, low-glare canopy coverage across a 2x2ft tent at full intensity and up to 2x4ft for supplemental or vegetative-stage coverage. A 240W Meanwell XLG driver runs the fixture off a 48V rail from standard 220-240V AC power, with 10-100% dimming so output can be tuned through veg and flower stages on the same fixture rather than needing to swap lights. The bar assembly measures 59.3 x 42.2 x 5.4cm; box contents are the 4-bar fixture, Meanwell driver, AC power cable, and mounting/hanging hardware.
