8 foot vho bulbs?

[Whaledriver]

Do you know of a source for 8 foot vho bulbs? I don't care if there are built in reflectors or not. I would like to run a typical actinic bulb along with a sunlight bulb. I would also be interested in overdriveing a regular bulb that hopefully has a shielded cathode on the ends. The problem is finding the bulbs

Has anyone used bulbs built for the tanning bed industry? They seem short lived and they have odd spectrum, don't they?

Thanks for the help, I will be useing A4 and 660 ballasts.

VHO wouldn't be overdriven "i believe".

NO bulbs are a little easier to find (not sure about color temperatures) but they would be overdriven.

I would be scared of the UV effects of using tanning bed bulbs.

Me personally, I'd use 2X4' bulbs instead of single 8'. Your not going to be able to squeeze any more bulb length out of the ballast by using 8' anyway.
