Digital Ballasts

Digital ballasts control the power delivered to HID grow lamps, providing smoother ignition, more consistent output and greater efficiency than traditional magnetic coil ballasts. A quality digital ballast also extends lamp life and reduces heat output.We currently stock two high-performance digital ballasts. The OCL 750W XL Series is a robust, high-output ballast for 750W HPS or MH lamps. The Lumatek Ultimate Pro Ballast 600W/400V (lamp not included) supports 400V super-lumi operation for maximum HPS performance.For complete HID systems, browse our Grow Lights range.
