    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Ti-force, Your right, there is nothing wrong with the shining beam board and running at medium. This was the best suggestion given, and that is what I'll do. Again, thank you.

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Thanks for all the input. The options for a micropuck at 3.7V input are not that attractive. http://www.ledsupply.com/docs/MicroPuck-Applications.pdf Assume I can make any necessary modifications (series or parallel battery holder), and also assume I don't want to buy a new light (despite...

    p.s. that is one spooky looking candle...foot candle...I get it...but I am still going to have nightmares!

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Message recieved...thank you for the link. Any guess as to how long it would be powered at 440mA? And is there any benefit runtime wise between Li Ion v. NiMh? (If just a toss up, NiMh would perhaps be safer and easier, Yes?) Again, thank you.

    I was told my thread, S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A? would be more appropriate for "Homemade and modified" section. Since I have not recieved any answer to the question presented in the thread, could the thread be moved to the Homemade...

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Thanks for the response...so is there any way to achieve 500mA to an XP-G (3.1Vf) for at least 2 hours utilizing only 3X AAA batteries (any configuration and with any driver)? That is my question. And if the answer is no, then which configuration/driver provides 500mA for the longest duration...

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Message recieved...and I said parallel when I should have said series. So in series, Li ion 11.1V @ 350 mAh's, so if I want to drive XP-G (Vf 3.1) at 500mA, will using a buckpuck 500 work? And if so how long? Again thanks, any information is appreciated.

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Thank you for this information, it is appreciated. I will certainly use a heat sink. Will it work to use 3X AAA Li ion parallel, 11.1V @ 350mAh, and buck with a buckpuck 500? If so, what kind of run time could be expected? Also, is it possible to move this thread to the correct forum for...

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    Well...for one, I'm not independently wealthy! But more importantly, I am excited about upgrading my existing light (this will be my first mod). That is why it will be 3X AAA; the only thing I want to change is the emitter and corresponding driver.

    S.O.S. What is most efficient 3XAAA battery configuration/driver for 1 XP-G @ .5A?

    I am a novice who would like to benefit from your collective wisdom. I am a runner, and my schedule has me running well before the sun is up. I use a 3X AAA headlamp with one very dim LED. I want to upgrade to one XP-G LED, and run at 500mA (Vf 3.1V and approximately 190 lumens) for at least 2...
