SMART 880 SL is a full‑spectrum, 8‑bar LED grow light from NĹŚKOTECH designed to operate as a slave unit to the SMART 880 master or the SMART controller. The fixture draws 780 W by itself (880 W with optional UV/IR bars), outputs up to 2100 μmol/s PPF at 2.7 μmol/J efficacy, and uses San’an white and Osram red diodes. It measures 1088 × 1140 × 70 mm and weighs 13.4 kg (net). NĹŚKOTECH lists average PPFD above 1100 μmol/m²/s at 30 cm and provides a 3×3 ft PPFD reference footprint; spectrum presets (V1, F1, VS, FS) and UV/IR bar control require the master unit or controller. The light runs on 120–277 V with knob or controller dimming, carries a 3‑year warranty, and has a stated lifetime over 55,000 hours.
