RCR 123 question

[Lynn Downey]

Can I use RCR123A batteries in my SF E1L and the E2L? Will they overrun the bulb and either blow or shorten its life? Also, can I use RCR123's in my 9P (with a cree Q5), my Z2 (with a cree Q2) and my 6P (with a cree Q5)? I know they are basic questions and I apologize but I'm unenlightened and striving to overcome that.

Not answering your questions directly.

I have a 6PL with the stock Seoul P4 and I use 3.7 volt AW's RCR123A with no issues.

The E1L and E2L are LED lights with no bulb to burn out, so the question is a little confusing (suggesting that maybe you are talking about the E1E and E2E)... anyways.. I don't know much about the new E series LED setups, but I seem to recall reading that some folks were running the E1L on a RCR123 without problems, but I don't want to say for sure, you could probably get away with some 3.0V LiFeP04 cells if you want rechargability that won't change the input voltage too much from using regular primary cells. however they will only deliver about 1/3rd the runtime of primary cells.

For your 9P, Z2, and 6P simply telling us which emitter you have does nothing to help recommend a battery configuration, however, IF the drop-in module you have in the 9P is the same as the ones in the 6P and Z2, AND you have run the 9P with the module on 3xCR123 primary cells, then you can safely run the 6P and Z2 on a pair of RCR123 3.7V cells with no problem. The 9P would be much better off with pair of 17500s (2 cells that fit the space of 3 CR123 size cells). I don't think I would recommend running the 9P on 3xRCR123s as the amount of voltage that would have to be bucked would be pretty high, which may cause the board to overheat depending on what it is designed to handle.

If you are using drop in LED in your surefire's its not a matter of blowing the bulb or emitter. It can and will cause damage to the circuit board. If you have a Q2 drop in from gene malkoff for example his high voltage is 9.0 put three rechargable batt's on it and it goes its not built for any voltages over the 9.0. so put it in a 6P and drop 2 RCR 123 in and you will be fine.....

Or you could just sell all of the surefires and build Mags then you would have something....

BTW no Li 17650 in the area !:mecry:

Thanks for all of your responses. I'm enlightened on this matter now. And for your info jff, I bundled six of my sf's together last night and came up with 600 lm of cree white across the back yard, not unlike one of your ridiculous mags. And nothing got hot !!
