For multiple banks of HID lights choose Green Power commercial contactor units.
These units send power to your HID lighting ballast bank-by-bank, reducing the surge you get from HID lights on start up. Green Power commercial units use heavy duty contactors and delays which allow you to switch HID lighting on safely. Additional safety is provided by the world-renowned Grasslin timer which is powered by a quartz crystal back up and built-in trip fuses to provide extra protection against any power surges.
Note: These units need to be wired in by a qualified electrician.
