Get maximum yield with a powerful, slim-profile full-spectrum LED that outperforms traditional 1000W DE fixtures.

The PHOTOBIO CX 2125 is the most powerful LED fixture in the PHOTOBIO lineup, designed for horticultural professionals who demand maximum photon output, better canopy penetration, and lower power consumption. With an impressive 2,125 µmol/s output at 2.5 µmol/J efficiency, this 850W LED grow light outshines traditional 1000W DE fixtures—delivering higher intensity, better distribution, and full-spectrum efficiency. Its 2.6" slim profile maximizes vertical grow space, while passive cooling fins maintain low operating temperatures for consistent, high-performance lighting.

Is the PHOTOBIO CX 2125 Energy-Efficient?

Yes. With 2.5 µmol/J efficacy, the CX 2125 outperforms 1000W DE HPS (1.7–2.1 µmol/J) while reducing energy waste and heat output. Compatible with Autopilot PX controllers and PHOTOBIO’s AC Power Distribution Tree, it allows seamless multi-light integration, cutting infrastructure costs while maximizing yield potential.
