At my church, just about every fixture has at least 1 failed lamp, and I was wondering what you guys thought was the best low mercury T12 tube was (Full mercury tubes don't seem to be available locally.) I know that y'all don't like Alto's, but that leaves Sylvania Ecologic and GE Ecolux. Color would be Cool White, of course.

All T12 fluorescent With low mercury are piece of crap. if you want a low mercury lamp with high performance please advance to the new T5 lamps. they are super bright, operating on electronic ballast and have a life of 24000h.

Sorry to say, but not all low mercury T12s are pieces of crap, I'm quite fond of GE Ecolux lamps, they last there rated lives!

In the 4' size, it looks like Sylvania's F40/CWP is full mercury and full wattage. The same goes for F40/CWX. Keep in mind that the light output of these phosphors is a little lower than standard cool white, although the CRI is higher.

I agree, so far Sylvania are recommended, they even still make some specific tubes made in the USA....So far I must say for T-12s use Sylvania!
There would be some reasons why thicker tubes can be better design is in some cases depending on the ballast used, sometimes when thinner tubes dies sometimes something happens on the ends and it starts rectifying and causes some cracking or burning on the glass and at times the tube will break....
I don't see that type of issue happen on T-12s but on T-8s and I can imagin on T-5 too

I know that GE makes at least some of their T8s in Canada (I have 6 Canadian GE F32T8s), but where do they make their T12s? I have a GE F20T12 that is probably from the '80s, and that was made in the US.

Random Guy,
Welcome to L-G!
Jace (Tudorwhiz) referred me to this thread, and yep thats me (Silverliner).
I'd be happy to help date your lamps. You can send me a private message or email me at chipsfan77@gmail.com or post pics of the lamps and I'll help date em.
By the way both GE and Sylvania T-12s are still decent so you can't go wrong using them. You can get a good deal at Lowes.
Regards, Dave
