The PHOTOBIO•CX 2125 100-277V S4 is a compact high-performance LED fixture with the highest photon output fixture within the PHOTOBIO product lineup. This high-efficiency compact top light is designed for horticultural professionals looking to increase performance and yields while minimizing power consumption. The CX is truly a direct 1:1 replacement for 1000W DE fixtures offering higher photon flux, more light to your plant canopy, and better overall distribution vs 1000W DE’s. The 2.6″ Slim vertical design is optimal for maximizing vertical real estate, while passive cooling fins keep the operating temperatures low. CX features iLOC Integrated Light Output Control push-button interface allowing the grower to adjust the photon output based on crop maturity. The high-efficiency S4 spectrum provides more red, far-red, and blue wavelengths to deliver vigorous growth and optimize flower development.
