Cree D26 question...

I am wanting to order a wolf-eyes cree P4 HO(D26) rated at 170 lumen for my SF C2. I know a 17670 rechargeable battery will work for the 130 lumen lamp, but will it push the 170 lumen module?

:thinking:

You can get your C2 bored out to use 18650's

cbclemons,

I too have the same set up in a C2. I sent you a PM response from AW asking him the same question.

Yes you can use the 170 lumens HO Cree with 17670 cell from AW.

I use this setup with my Surefire M2 and Digital HO 170 4-mode from W-E.

No problem. Great setup. Just less runtime than with 18650 cell (2200mAh vs. 1600mAh).

2200mAh gives ~110 minutes runtime.
1600mAh will give ~80 minutes runtime.

Thanks for the info guys...very helpful. Thanks for the PM Tman11; all my questions were answered!

:thumbsup:

Will either of these battery combinations fit a Surefire G2 ??

So the 17670 gives the longer runtime....correct?

Thanks!

Ray

Yes longer with 17670, unfortunately 18650 doesn't fit G2, or it would have been the ideal partner.

i was thinking of gettin 1 of these 170Lumen crees...i just checked out the price and i was suprised at the price...i was thinking it would be $30 at the most...i guess i'll probly never get my hands on one:mecry:...maybe they'll get cheaper some day!!

WHAT! I talked to Mike on the phone and he said the 170 Lumen HO Cree needed at least 5 volts...maybe he meant to say amperes...I'll have to send an e-mail. I just got my 130 lumen Cree

I noticed the voltage difference also. When I run just one 18650 at 3.7v it seems to run just as bright for the first 30 minutes or so (maybe). Afterwards it's much cooler and slightly dimmer but exceeds 1 hour+. When I use 2xRCR123 at 3.7v each it runs hot all the way until failure which is around 1 hour 6 minutes. Maybe the 18650 is not running regulated?

I'm talking from the 3,7V-6V version dropin (130 or 170 lumens)
It is regulated with one 18650/17670 cell, or with 2xcr123's.

But concerning the 3,7V-13V version dropin (130/170 lumens), it's true that the dropin is regulated only from 4,8V.
Use with 17670/18650 is not regulated, but you have longer runtime.

I have a 130 lumen 3,7V-13V dropin that I use with 2xRCR123's for maintaining regulation, and have also the Digital dropin 4-mode (3,7V-6V), WICH IS REGULATED with single 17670/18650 cell.

Be sure you'll buy the 3,7V-6V dropin for use with 1x 17670/18650 and maintain regulation !
