Light Spectrum
S4 Spectrum: Provides highly efficient full spectrum with a healthy red-to-blue ratio to drive photosynthesis. Light energy between 500–599nm, previously thought wasted, penetrates deeper into the plant canopy promoting photomorphogenic responses. High color rendering “white” light aids to rapidly identify potential threats to your crop and provides superior working conditions and safety for personnel. Ideal for both flowering and vegetative production.
Why the PHOTOBIO CX 2125 Is a Top Choice for Commercial Facilities
With 2.5 µmol/J efficacy, advanced optics, and industrial-grade construction, the CX 2125 delivers serious performance in a slim, durable frame. It’s a go-to solution for professionals replacing HID fixtures or scaling high-efficiency indoor facilities with confidence. The integrated dimming system and compatibility with PX series controllers give you total control over light output at every growth stage.
