Bridgelux’s V Series V18B (Gen 9) is a 36 V chip-on-board LED array supplied as a light engine for luminaires rather than a complete grow fixture. On the official V Series page, the V18B lists a 19.6 mm LES on a 24.0 × 24.0 mm substrate, nominal drive current 700 mA and typical forward voltage around 34 V, producing about 4,720 lm at CRI 80 depending on CCT. From the Gen 9 V18 datasheet, typical input power at 700 mA is 23.8 W, and CRI 80 variants reach roughly 190–200 lm/W efficacy. The COB has a broad 120° emission and is offered across common CCTs (2700–5000 K). Coverage area depends on holder, optic and luminaire design, not the array itself.
