Re: [AGA-sc] NEC

Interesting. I've heard claims of higher efficiency, but any time I've seen numbers, they are the same as the 5/12" diameter u-tubes.

Kim Bryant's commments about shipping are interesting -- due to the length/shape of T5s, the stress-in-bending load factor would be 4 times higher but the stress-in-bending strength would be about half of that of a u-tube.

Erik, have you compared any new T5s to the ones you've had running a few months? Just curious about the intitial burn-in decay.
