L-QB2
Grow Lights220W
The Niello L-QB2 is the larger board in the L-QB pair, drawing 220W against a traditional 2000W HPS/MH lamp. Same spectrum as its smaller sibling — 3500K and 6500K white with 660nm red and IR — on a bigger board.
Coverage is 120*120cm in veg and 90*90cm in flower. Take the flowering figure as the real one if you are buying for a single tent; the veg number is the same light spread thinner. Niello single out the IR as useful during flowering specifically.
Cooling is passive through a thick 3 mm aluminium heat sink, so it runs silent, and the diodes sit under a glue coating. Niello quote IP67 on the LED coating and IP65 on the fixture. After-service is 3 years.
