Monster Board 320W V4 is a quantum-board style LED fixture from Geeklight’s Monster Board line, built around Samsung LM301H white diodes supplemented by 660 nm deep‑red and optional UV/IR channels. The board-form design concentrates diodes across a large aluminum plate with passive cooling and onboard dimming, intended for compact grow spaces. In typical use, 320 W LED quantum boards are configured to flower a 2x4 ft plant area with balanced intensity and even coverage. Vendor specifications for the V4 series cite roughly 50,000 hours service life.
