Ballast Info for TWO lights

Has anyone ever come up with a single ballast that will power two HPS lights? say- 400 / 600 watts each? Electricity is just eating my ass up.

I don’t know if such a device exists but…If it does it will not reduce the amount of electricity used. That is a function of wattage.


If you could wire them 240 v it would help.
Cut the amperage in half.

While the amperage would be cut in half, the wattage (which is what we are billed for) remains the same. Wattage = Voltage X Current
