Bridgelux V Series HD V4B – Gen 8 is a compact, ultra‑high‑lumen‑density COB LED array for high‑intensity spot and accent luminaires. The V4B variant (BXRH‑xxx0600‑B‑8x) uses a 4.8 mm LES on a 12.5 × 12.5 mm substrate and is specified at 6.4 W typical power when driven at 350 mA with about 18.3 V forward voltage. At 3000 K, 80 CRI, it produces roughly 868 lm (typical). The Gen 8 family offers CCT options from 2200–5000 K and CRI choices of 80, 90, or 97, with tight beam control and excellent color‑over‑angle uniformity, positioned as an efficient replacement for ceramic metal halide in showcase‑grade directional lighting. Beam width and usable coverage depend on secondary optics; Bridgelux provides mechanical models and ray files for optical design.
