MIXJOY GL-4000d

MIXJOY GL-4000d is a 450 W full‑spectrum LED grow light built around Samsung LM301 diodes and a Mean Well driver. The fixture uses a four‑board quantum‑style layout totaling 1,212 LEDs and includes onboard dimming plus a daisy‑chain control box, allowing a single unit to adjust multiple lights. Retail listings specify bloom coverage up to 5×5 ft and note enhanced red/IR components for flowering. The panel measures roughly 21 × 25.4 × 2.3 inches and mounts with standard hanging hardware. This configuration targets even canopy intensity for tents around 4×4 to 5×5 ft, with efficiency-oriented white LEDs supplemented by deep‑red output. Specifications are drawn from brand‑named retail product pages that list the same model and hardware.
