Description
850W high voltage LED with 2.5 µmol/J efficacy, 2125 µmol/s PPF, S4 spectrum, iLOC dimming, and IP66 durability for pro-level greenhouse grows.
The PHOTOBIO CX 2125 347–480V is the most powerful compact toplight in the PHOTOBIO lineup—delivering 2125 µmol/s of balanced S4 spectrum in an 850W slim-profile design. Built for high-bay greenhouses and commercial grows, it replaces 1000W DE fixtures 1:1 while offering better light distribution, deeper canopy penetration, and lower power draw.
The CX 2125 is equipped with premium Osram/Seoul diodes and features integrated iLOC dimming controls, passive thermal management, and a high-voltage 347–480V input for industrial-grade applications. This fixture is tough, efficient, and built for serious productivity.
Is the PHOTOBIO CX 2125 energy-efficient?
With a rating of **2.5 µmol/J**, this fixture outperforms standard HPS lights (typically 1.3–1.7 µmol/J) and even rivals some premium DE HPS units. You’ll reduce energy waste and heat load while delivering more light per watt—translating into stronger growth, higher yields, and lower operating costs over time.
