The FLUXengine v2 LED Module from Crescience is a DIY horticulture board built around Samsung LM301H mid‑power diodes. The v2 raises the permissible drive limit, allowing up to 80 W at 4 A with suitable cooling, while typical operation at about 1.3 A draws roughly 25 W. The board delivers a typical PPF around 76 µmol/s at 3500 K with a wide 120° beam. Mechanical dimensions are 240 x 40 x 7.5 mm for easy mounting to extruded heatsinks. Crescience’s PPFD database includes measurements for a single FLUXengine v2 run at 1300 mA in an 80 x 80 cm tent, useful as a coverage reference. The original FLUXengine line has since been retired in favor of newer modules, though replacements may still be available.
