QB-132 Mini LM301B is Lientec LED’s compact quantum grow board for DIY and modular builds. The single board carries 132 Samsung LM301H diodes and runs at roughly 60 W when driven at 1400 mA with a 36 V constant‑current driver such as Mean Well LPC‑60‑1400. Lientec lists a forward voltage of 30–40 V DC, a 115° beam angle, and a bare board size of 326 x 240 x 2 mm weighing about 0.25 kg. Offered in 3000 K, 3500 K or 5000 K whites, the board is suitable for propagation, vegetative growth and flowering as a primary or supplemental light. A separate heatsink is not required at 1400 mA. Multiple boards can be wired in series, and Lientec offers dedicated frames for 2 to 12 boards.
