The Migro ARAY 4 (≈240–250 W) is an expertly engineered, high-efficiency LED grow light designed specifically for compact grow spaces measuring around 4 x 2 ft (120 x 60 cm). Drawing approximately 250 W, it achieves a notable efficacy of around 2.7 µmol per joule, balancing powerful output with low energy consumption. Hosting four modular bars loaded with Samsung LM281B+ white LEDs and Osram 660 nm deep-red diodes, the unit delivers full-spectrum illumination suitable for every stage of growth, from seedlings through flowering. Interior coverage remains impressively uniform, producing an average PPFD of approximately 813 µmol/m²/s when hung around 25 cm above the canopy. Migro provides a highly efficient and performant light system so it’s worth taking a look at their other products such as UVB 310 or their Migro Aray 8 480W.
