Pro-emit’s SMD Performance Bar 120W is a compact DIY LED grow light designed for narrow spaces. The bar draws 120 W and outputs 336 µmol/s at an efficacy of 2.8 µmol/J, using Samsung LM301B full‑spectrum diodes supplemented by Osram Deep Red and Far Red emitters. It is intended to cover areas up to 100 x 50 cm and includes a Mean Well HLG-120H-C1400A driver with onboard dimmer (50–100%). Passive cooling keeps operation silent, while a 3 m cable and integrated driver simplify mounting. The aluminum bar measures 79 x 8 x 6 cm and weighs 2.645 kg. Rated lifetime is 50,000 hours. Optional clip-on protective lenses are available to focus light and reduce glare.
