The Autopilot PX2 Advanced Lighting Controller provides precision photoperiod control of up to 512 fixtures in two independently controlled zones, all from one centralized location. Designed to work with any controllable Phantom or Core HID fixtures, as well as PHOTOBIO LED fixtures, the PX2 can control 512 digital HID fixtures (256 per zone), or 100 analog LED fixtures (50 per zone). The PX2 offers the flexibility to operate both zones analog or digital, or one zone analog and the other digital. With this versatile, dual-zone configuration, growers can optimize spectral treatments by checkerboarding lighting technologies within the same environment (e.g., HPS with CMH, LED with CMH), save power by checker boarding identical fixtures while reducing output to one of the zones during the light cycle within the same environment, alternate rows and zones within the same environment, enhance uniformity by independent control over perimeter versus interior of the environment.
