Niello’s M300 is a compact blurple LED panel marketed as “300W,” with an actual power draw of about 120 W. It uses a 12‑band full spectrum (380–740 nm) and two spectrum switches (VEG/BLOOM) for seedling, vegetative, and flowering stages. The fixture employs 60 Epiled/Bridgelux 5 W diodes behind a dual optical‑lens design for improved penetration. Recommended coverage is roughly 75×75 cm (core) at 24 in/61 cm hanging height, with a maximum area near 95×95 cm. The housing integrates an aluminum heat sink and active cooling fan. Dimensions are about 31×17×6 cm, and weight is around 2.1 kg. Rated lifespan is listed at 50,000 hours, and Niello advertises a three‑year warranty on this model, positioning it for small indoor grows and tents.
