The Maxibright Daylight 315w CDM (Ceramic Discharge Metal-Halide) ballast has all the incredible features of the DigiLight ballast range but additionally is designed to get the best out of the Philips 315w CDM lamp included in the kit. The ballast features Soft-Start technology to help avoid nuisance tripping on start-up, particularly if you have more than one of these units starting up at the same time. On top of that, the Daylight ballast includes end-of-lamp-life detection, dynamic frequency control, short-circuit detection, thermal protection and auto-reset. The unit runs silently and is reasonably lightweight.
A Maxibright Daylight 315 CDM grow light gives out an intense full spectrum, high PAR light that is as close to natural sunlight as a digital HID grow light can produce.
