killrblue Posted August 26, 2003 Share Posted August 26, 2003 Is it OK to run a double ballast for 1 MH pendant? I will be adding another pendant when I eventually upgrade my tank to a 20L someday. Link to comment
Physh1 Posted August 26, 2003 Share Posted August 26, 2003 Yes...my PFO ballasts (2) are both doubles and they have switches for each bulb. You don't need to have both hooked up to use it. My Hamilton ballast is the same also. Cameron Link to comment
