vho holders

[rossb]

I am currently making a new light hood and was wondering how you could connect and hold a couple of VHO 4' bulbs. I priced out some coralife end caps and brackets .. but they were 31 bucks. That was more than I paid for the bulbs. I need to separate them by about 8" so I can fit a couple of 175W pendants between them at either end. Does anyone have a DIY (read cheap) way to do this?
