I want a billboard fluorescent fixture. Attached is a T5 version.

You see these on sides of buildings lighting signs or otherwise.

Looking for a T12 HO version, I think these are remote ballasted, Any length is fine, 4, 6, 8 etc. A T8 version would also be acceptable but no dinky T5 stuff.

Got one? Know where I can find one? Seems to be a secret where to buy them, but then again who wants to sell Fluorescent any more..

Not for any specific purpose other than I want one, know the feeling?

I love those too I wish to find as well. I hope a 6' one come my way!

I would recomend ringi up electrical supply houses
In Arizona as i find lot fluorescent bill board lighting
In  use there.  Cause  they  have strict lighting
Codes there. 

Somewhat related, there exists fixtures kind of like this used typically in classrooms to light up the chalk board. I taught a bit in a school that had them, and they do a fine job. They were all F40T12 single lamp tandem mount, but I imagine they are available in T8 as well. They appeared to be solidly built, too.

At electrical counters, they should be available (both types).
