The Kingbrite P55 480W is a full-spectrum LED bar-style grow light built around Samsung's LM281B diodes, a step up in scale from the 240W model for a larger tent or a second grow area. Six slim light bars carry 1,680 LEDs in total: 224 Samsung LM281B diodes per bar provide the core full-spectrum white light, supplemented on each bar by 48x Epistar 660nm deep-red, 4x infrared, and 4x UV diodes to support flowering and secondary metabolite production. Rated efficacy is around 2.47 µmol/J (CRI 80), giving even, low-glare canopy coverage across a 4x4ft tent at full intensity and up to 5x5ft for supplemental or vegetative-stage coverage. A 480W Inventronics driver runs the fixture off a 48V rail from standard 220-240V AC power, with 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; box contents are the 6-bar fixture, Inventronics driver, AC power cable, and mounting/hanging hardware, backed by a 3-year warranty.
