O+ Series 150W

Groplanner O+ Series 150W (GPM150) is a dimmer‑knob controlled quantum‑board LED grow light designed for small tents. It draws 150 W and uses SMD 2835 chips on a full spectrum array combining 3000 K and 5000 K whites with 660 nm deep‑red and 760 nm far‑red. Groplanner rates the efficacy at 2.75 µmol/J. A built‑in Mean Well driver supports stepless dimming and daisy‑chain control via a main/sub‑light setup. Recommended coverage is 3×3 ft for vegetative growth at 18–24 in and 2.5×2.5 ft for flowering at 12–18 in. The passive finned heatsink enables fanless operation. Nominal lifetime is 60,000 hours. This O+ variant differs from the Wi‑Fi O Series by offering physical knob control without app connectivity.
