Really? Wow, this could be interesting :wink:

Thanks for the info Franklin :biggrin:

I actully preffer the VHO, i bought Tonys old pair of VHO and the antic lighting is better then anything else i have seen.
I changed it over to a icecap ballast but for sure they have much better color then any 4 t5 bulbs that i have seen.

My friend measured and from screwhole to screwhole is 69 5/16" There seems to be a discrepency in measurements.

yeah I'm wondering if there are a few different types of endcaps out there. I ended up measuring my 4 foot ones and came up with a half inch off the bulb length so I told my builder that. No worries though, if its more or less I'm sure it can be adjusted somehow.

There are indeed. Icecap makes some, and there are the ones you can buy at Big Al's (which I personally prefer), Lifereef/litereef perhaps???. Likely others as well.

I believe my friend uses Ice cap end caps.

Well that certainly explains it, I didn't realize that (although, duh, I should have!)
