Lientec LED’s Cree CXB3590 Set – 300W mit Rahmen is a DIY COB grow-light kit built around four 75 W or six 50 W CXB3590 36 V LEDs driven by a Mean Well HLG‑320 constant‑current driver (C1400A or C2100B). The kit includes heatsinks, holders, wiring, EU power cord and mounting hardware, plus your choice of 60°, 90° or 120° glass lenses or a 90° reflector. Color temperatures span 2700 K to 6500 K with CRI options up to 90. The extruded‑aluminum frame measures 710×750 mm (4×75 W) or 550×1040 mm (6×50 W). At 300 W, comparable horticultural LEDs typically cover about 100×100 cm; real coverage will vary with the selected optic and hanging height.
