With an increased diode count and optimized layout, light efficacy, PPF output, and uniformity remain consistent with the previous Samsung-based version—helping you achieve reliable yields.
• HIGH EFFICIENCY & PREMIUM U.S. BRAND DIODES: The SF Series is engineering-upgraded with high-performance Bridgelux diodes, increasing diode count so each LED operates under lower load for reduced stress, improved thermal stability, and extended lifespan. Veg footprint is 5 x 5 ft, Flowering footprint is 4 x 4 ft.
• DIMMING DESIGN: The dimming knob can adjust the light intensity at liberty. Multi-light Connection with unified dimming is especially beneficial for large areas of indoor growing and commercial planting.
• IDEAL FOR ALL GROWTH STAGES: With excellent full spectrum light – white, blue, red and IR (3000K, 5000K, 660nm and IR 760nm), the 3000K diodes provide more reddish light and the 5000K diodes provide more blueish light. The 660nm red and IR light is especially useful during blooming stages as it speeds up flowering time and boosts yields. Turn your seeds into your own supply!
