Ortoled 4 is a quad-band LED grow light from Ortoled designed for compact grow areas. The unit draws 140 W (real) and uses 60 × 3 W diodes arranged in four clusters behind 120° optics. Its spectrum combines deep red 660 nm, red 630/610 nm, and blue 460 nm for growth through flowering. Recommended coverage is roughly 0.25–0.8 m² depending on mounting height. The lamp is passively cooled for silent operation, powered by a 32–45 V DC driver, and features a corrosion-resistant aluminum front panel. Dimensions are approximately 23 cm diameter × 10 cm; weight about 3.65 kg. Ortoled notes fixtures can be used singly or in arrays to scale light over the canopy.
