Niello L-QB2 is a passively cooled, fanless LED quantum-board style grow light aimed at 4x4 ft vegetative spaces and 3x3 ft flowering areas. It draws about 220 W (±5%) and uses a sunlike full-spectrum mix of 3500 K and 6500 K white LEDs with 660 nm deep-red plus IR to support growth from seedling through bloom. The board is coated for water resistance (IP65) and built on a 3 mm aluminum heat sink to manage temperatures without noise. Niello lists a 50,000-hour lifetime, 100–240 V AC input and a power factor of at least 0.98. Recommended hanging heights are 45 cm in veg and 35 cm in flower to cover approximately 120×120 cm and 90×90 cm, respectively.
