MIXJOY’s GL-2000 is a 220 W, fanless LED quantum-board style grow light built around Samsung LM301B diodes and a dimmable Mean Well driver. The board carries 436 LEDs across a full-spectrum array, mixing 3000K and 5000K whites with 660 nm red and IR for seedling through bloom. Rated efficiency is up to 2.7 µmol/J, with reported PPFD around 1106 µmol/m²/s at 12 in in the center. Recommended coverage is about 3 × 4 ft in veg and 2 × 4 ft in flower, matching common 2 × 4 ft tents. Passively cooled aluminum heat sink and 0–10 V dimmer minimize noise and simplify intensity control. Listed item weight is approximately 3.63 kg. Suitable for small to mid-size tents where quiet operation is preferred.
