Yearld Pro 330W is a full-spectrum LED bar fixture built around Samsung LM301B white diodes paired with Osram 660 nm red, powered by a dimmable Mean Well driver. Actual draw is 330 watts, with a rated efficacy of 2.6 µmol/J and total photon flux of 858 µmol/s. The white channel is approximately 3920 K, complemented by deep-red 660 nm to improve canopy penetration. Recommended coverage is about 6 x 3 ft in vegetative growth and 5 x 2.5 ft in flowering. The fixture measures roughly 46.46 x 21.85 in, supports 100–277 V input, and ships with hangers, an RJ-style control cable, and a US power cord. Some retailers mark this model discontinued, but the listing remains useful for specifications and footprint guidance.
