Pro-emit’s Model B 300W is a COB LED plant light built around four Cree CXB3590 arrays driven up to 75 W each (total 300 W). The square, passively cooled frame measures 64 x 64 x 8.15 cm and weighs 10.6 kg. Two Mean Well ELG‑150‑C2100B drivers with an external potentiometer provide stepless 0–100% dimming. Designed for square footprints from 80 x 80 cm, it suits compact tents and cabinets. Buyers can choose color temperatures of 2700 K, 3000 K, 3500 K, or 6500 K to match veg or bloom. Pro-emit introduced the Model B series in July 2018, identifying the 300W variant with four COBs and guidance for coverage from 80 cm square while emphasizing silent, fanless operation.
