I wouldn't run a P91 with 17500 LiCo cells. There are no IMR 17500's yet either.
AW 17500 LiCo's are 1100mAh. The P91 draws 2.7A. That will exceed the 2C max discharge limit of LiCo cells.

For absolute max output the IMR-9 needs IMR18650's, for which it was designed.
The SF P91 will :poof: with IMR18650's, it should be ok...

I have no idea if it's the same as the HPR71. Perhaps some one can confirm it for us.
EDIT: Didn't realise the HPR71's a potted bulb, this one is bi-pin. Still may be useful.
Re: A2 dumb LED rings - (Onion Ring)
Woot!! These are finally becoming a reality :grin2:
I'm still in for my original order of three, preferably with DIP sockets. LED's not required.
