Sun Sytem 315 daisy chain, ballast 2nd unit?

Curious if i can hook up a second light to my Sun System 315 cmh without requiring a second ballast unit?
Can i just get a second reflector and light or will i require a whole new unit?


Cheers rollers..

One 315 ballast will run one bulb. Are you talking of a flip where the ballast runs 1 bulb for 12 hours then it runs the other bulb for 12 hours?
