680W GH Top Light LED (White + Red)

Photontek’s 680W GH Top Light LED (White + Red) is a slim greenhouse fixture optimized for vegetative stages, low‑PPFD flowering targets, and vine crops. It draws 680 W and outputs 1805 μmol/s at 2.7 μmol/J, using higher‑spec Osram and Seoul diodes with passive thermal management. The wide 100–120° beam angle aids uniform canopy distribution in row installations. The fixture supports on‑board dimming and external 0–10 V control (Photontek or universal controllers), plus daisy‑chain linking. Rated IP65 and certified CSA/FCC/IC, it is built for greenhouse environments and carries an L90 > 50,000‑hour lifetime and a 3‑year warranty. The compact housing measures 25.7 × 10 × 4.6 inches and weighs about 8.8 kg (19.4 lb) for easy mounting above crop trellises.
