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.

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.

🌟 Feature Highlights

S4 Spectrum for Full-Cycle Growth
More red, far-red, and blue output improves flowering and vegetative development while maintaining worker safety and comfort.

Secondary Optics for Light Precision
Built-in optical lenses boost canopy penetration, increase light utilization, and protect LED diodes from dust and damage.
