Our Sun System VI ballast uses our popular extruded aluminum housing and incorporates a new unique feature. The switchable ballast runs a metal halide 1000 watt (either universal or super) or a high pressure sodium 1000 watt lamp. To change from one to the other, merely insert the appropriate lamp and set the switch to the correct operating setting. This enables growers to bypass costly conversion lamps with less lumen output. It allows growers to utilize the proper spectrums for vegetable growth(metal halide) as well as flowering(high pressure sodium) with a simple to use switch. All ballasts wired 120 volt, unless specified otherwise.
