Hi, can anyone recomend a ballast (preferably available @ homedepot, lowes, etc) that will run 2-4 24" [acronym:a905a2794f="Very high output fluorescent"]vho[/acronym:a905a2794f] bulbs. I would like to be able to control the bulbs in pairs but cost is the reason for this question so I may have to settle on all 4 bulbs on one ballast. [acronym:a905a2794f="Thanks in Advance"]TIA[/acronym:a905a2794f]
