The SANlight S4W is an LED grow light designed for efficiently illuminating smaller indoor cultivation areas. With a power draw of 140 W and a high photon flux (PPF) of 384 µmol/s, the S4W delivers outstanding performance for demanding grow environments where high light intensity is essential. Its exceptional module efficiency of 2.9 µmol/J ensures that most energy is converted into usable light, not heat, optimizing both energy savings and plant health. The fixture features a 90° beam angle and carefully engineered optics to provide uniform, rectangular light coverage, minimizing shadow formation and ensuring even light distribution down to the lower canopy. The full-spectrum output supports all stages of plant growth while offering high color rendering for easy visual inspection and early pest detection. With passive, silent cooling and a 3-year warranty, the SANlight S4W offers reliable, maintenance-free operation and long-lasting performance. The SANlight S4W is perfect for covering 80x80cm areas. Need more coverage? Consider the Q6W Gen 2, suited for 100x100cm areas. Need less coverage? Consider the S2W 62W, ideal for 60x60cm areas.
