Niello LED D600W is a bar-style COB grow light from the brand’s D-series. Retail listings specify a 600 W class with approximately 210 W actual draw from the wall. The fixture uses three warm-white COB modules set behind glass lenses and reflective cups, with active cooling via three fans. At 24 inches hang height, the stated footprint is about 4×3.5 ft core and up to 5×4 ft maximum. Dimensions are roughly 60×10×9 cm and weight around 2.7 kg. It runs on AC 100–240 V and targets a broad photosynthetic spectrum (about 380–780 nm) suitable for veg and flower. This model is appropriate for small tents where a focused COB bar can serve as a primary light or strong supplement.
