The Kingbrite P55 800W is the largest fixture in this full-spectrum LED bar-style grow light range, built around Samsung's LM281B diodes for large-tent or multi-plant commercial-style setups. Eight slim light bars carry 3,040 LEDs in total: 312 Samsung LM281B diodes per bar provide the core full-spectrum white light, supplemented on each bar by 56x Epistar 660nm deep-red, 4x 460nm blue, 4x infrared, and 4x UV diodes to support every growth stage from veg through flowering. Rated efficacy is around 2.9 µmol/J with roughly 127,321 lumens equivalent output (CRI 80), giving even, low-glare canopy coverage across a 5x5ft planting area. An 800W Inventronics driver runs the fixture off a 48V rail from standard 220-240V AC power, with 1-10V control and 1-100% 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 98.3 x 90.2 x 5.4cm, built from an aluminium-and-PC housing; box contents are the 8-bar fixture, Inventronics driver, AC power cable, and mounting/hanging hardware, backed by a 3-year warranty.
