QB240 is ParfactWorks’ 240 W quantum board built around Samsung LM301H white diodes (3000 K and 5000 K) with supplemental 660 nm red plus UV and IR for a full-spectrum output. The passively cooled panel includes manual dimming and RJ11 ports for controller-based 0–10 V dimming. It operates on autosensing 100–277 V AC and is rated at 2.8 μmol/J. Reported PPFD is about 1260 μmol/m²/s at 60 cm, weight is approximately 3.95 kg, and the claimed lifetime exceeds 100,000 hours. For practical planning, retailers categorize ParfactWorks’ 240 W board in the ~3×3 ft flowering coverage class. The form factor suits compact grow tents and single-plant canopies where a thin, board-style fixture provides even distribution without active cooling or fan noise.
