Under Canopy LED 120W by Ortoled is a 4‑ft supplemental bar designed to light the lower canopy zones missed by top lights. The IP65‑rated aluminum housing runs fanless (Sound Zero) and daisy‑chains up to 10 fixtures on one line. Ortoled specifies Samsung SMD2835 4000K white diodes paired with 660 nm reds for a Total Agro spectrum, with an expected lifetime over 50,000 hours. Retail specs list 120 W input, 120–277 V AC, 50/60 Hz, light distribution 120°, and PPF of 336–360 µmol/s at 2.8–3.0 µmol/J. The bar measures 115×7.7×8.1 cm and is intended to be installed roughly 20–30 cm from the plant sides to stimulate productive lower sites.
