Proton LED SMD 420W

With 420W of power and a PPF of 1218 µmol/s, LED Protón SMD 420W is the highest-performance panel in the Proton SMD range, designed to maximise a complete growing space. Its full spectrum supports the plant from growth through flowering, with a boost of deep red 660nm that improves yield and harvest quality.

Features of LED Protón SMD 420W

It features Samsung 2835 Plus diodes enhanced with deep red 660nm, for a full spectrum rich in oranges and reds. It achieves an efficiency of 2.9 µmol/J, superior to lower-wattage models, and evenly illuminates a recommended coverage area of 1 × 1 m (at 30–60 cm above the canopy, with a 120° angle). It is fully dimmable (0–100%) and features an RJ14 port for daisy-chaining multiple Proton SMD units. It operates on 185–265V and offers excellent longevity (L90 >50,000 h). It is one of our grow lights, ideal for fully equipping your indoor grow tent.
