BACKGROUND: I am in the final stages of finishing a DIY 34g AIO cube (20"x20"x20"). I need to install the lights. I'd like to use five 15 watt 18" T8 type bulbs commonly available at the big box home improvement centers. 75 total watts works out nicely for the 25g display area and the 18" bulbs will fit perfectly inside the hood.
PROBLEM: I cannot find a ballast that lists my light bulbs (F15W-T8-PL) and all the ballasts I look at are for 1, 2 or 4 bulb set-ups. Ideally I would like to use only one ballast but if I had to use two ballasts I'd opt for another bulb for a total of six bulbs and 90 watts.
Any assistance would be greatly appreciated, cause I'd rather not burn down the newly built home.
