Hi there,
I got the T1 and the 6PL with the regular surefire LED. So I cant say much baut the brightnes. Only that I think the 80 Lumens of the 6P are enough for almost every task I need it for. Yea - T1 on high kicks *** but you'll get used to that too and along comes a even brighter one.
I like the making and the finish of the SF better. It's engineered beautifuly; simple, functional and built to last. The clicky-switch of the Fenix is more complicated and has more parts than the whole 6P. Beeing an engineer myself, I just love SF for it's designs.
I got the T1 with that clip and it sucks. It is a great light, but get it without the clip (get the 6P instead).
PS: my favorite light is the G2L
. It is light, more durable than any aluminium light (concerning scratces and dents) and it never feels cold in winter. And it is brigt enough.
cheers
