Anyone have any suggestions on where to get 48" actinic bulbs for a good price? I plan on doing my own lighting on my 7ft tank I'm working on so I think since it is 2ft front to back and 31" deep I plan on doing four 48" dual bulb T8 shop lights so that there are two rows of them basically and just mount then so the extra foot hangs off the one side since it is an in wall tank that wont show at all. So I want to do a daylight spec bulb and a actinic bulb in each fixture so a total of 4 daylight and four actinic bulbs. The actinic bulbs seem pretty costly though so far where I look. So where do you guys get your actinic bulbs when you replace them?
