I have a Coral Life retro ballast that runs 2 65W compact florescent lights. The ballast contains 2 independent switches. This ballast is used. I am asking $20.00. Please contact me with any questions. The best way to contact me is through phone. I do check my e-mail daily. My number is 419-308-6807 and my e-mail is twiztedraceing@yahoo.com. Please ask for John.
