Are you all trying to become "Post Count Floozies". 
I'm still trying to figure out why a T-5 would have so much better output over time than a T-12. Not only that but it appears T-8's also share this attribute. According to the National Lighting Bureau, an NO T-8 can maintain 90% of its output for 15,000 hours where an NO T-12 only gives off 90% for a bit over 3000 hours. A VHO T-12 is only rated at 90% for a little over 2000 hours. They did not have a figure for a T-5 HO but if it works like the T-8 NO it would be a real saver in tube replacement.
What confuses me is why that should be. Wouldn't all size tubes use similar phosphors? I do know the T-5's are designed to run in an ambient temp of 95Ã"šÃ‚°F versus 77Ã"šÃ‚°F for a T-12. I suppose the T-5's and T-8's might use a phosphor that is more heat tolerant but that brings up the issue why it wouldn't be used in the T-12 .
Anyhow, I'll get to the bottom of this eventually.
By the way-- The only thing a high post count gets is a custom avatar. If you're bucking for Team RC or something I made the original team with a post count of under 300. Of course, that was before anyone knew what a pain in the old butt I am.
