    What is the max current I can expect from -

    [ QUOTE ] wtraymond said: I'm guessing that I'll get ~700ma max out of a AA Li-ion. Will a R123 provide more current than the Li-ion AA or just more capacity? Would the BB750 config do a better job than the BB1000 since the max current is only ~700 anyway? [/ QUOTE ] An AA battery is...

    What is the max current I can expect from -

    I can tell you right now that a single AA NiMH/NiCD/Alkaline/Lithium will not run a NexGen BadBoy, especially at a high current such as 750 or 1000mA. I also want to make clear the difference between an AA Lithium and an AA Li-ion. Energizer makes some Lithium AA batteries that run at 1.7V and...

    MM and NG with R123/RCR2

    I'm pretty sure NG's are not designed to protect against over-discharge. There may be a de facto protection since the converter will not light up below a certain voltage, but by that point you've probably already partially damaged the cells. The trick is to just pay attention and regularly...

    MM and NG with R123/RCR2

    Ray, Let me first say that the three emitters you listed above all have the same capability (for better or worse) to run safely off a Li-ion cell. That is, they are all J binned Vf. The tint (the X1, XO, and WO parts) don't affect the voltage characteristics. That being said, when attached to...

    Lux III & single 123 cell - Which converter?

    I'll third what Chop and Zulu have said. If your LED has a fairly low Vf then you might be able to get more than 750mA to the emitter, but 1000 might be too high. The nexgen would have been able to do better. Regarding measuring currents, it sounds like your multimeter is introducing too much...

    Lux III & single 123 cell - Which converter?

    [ QUOTE ] quantum said: Hi Srue, I got one of those cheapy 3watt luxeon flashlights on ebay. it runs on x3 'AAA'. direct drive, not even a resistor. I measured the current, it's about 120mA starting at 4.5volts and slowly drops. would the nexgen 750mA & single CR123 be much brighter than what...

    Lux III & single 123 cell - Which converter?

    If you want something that can both boost (raise the voltage of a single cell to the voltage of the LED) and buck (lower the voltage of multiple cells to the voltage of the LED), then you need a Wizard.

    Lux III & single 123 cell - Which converter?

    A Nexgen converter will be perfect. This may have been a typo, but you said "DB Nexgen". The Nexgen is a type of Badboy converter, not Downboy. Anyway, you definitely want a BB Nexgen. 750mA should be plenty bright. Enjoy.

    Second BB500 gone bad!

    Thanks. Hopefully this will vaccinate me against this particular problem.

    The retaining ring and the o-ring are the last two items on this page, right?

    different ways to use a nexgen sandwich

    I say go for it, but expect that you may burn out one or more components. I've been running a BB650 Lux3 on a R123 successfully for quite a while now, but a NexGen might fare differently. Also, the Vf of the Lux3 has a ton to do with it. One solution would be to get a high Vf. J = 3.27 -...

    different ways to use a nexgen sandwich

    The lithium AA have a nominal voltage of about 1.7V, so running 2 of them should be fine.

    4.2v Rechargable 123 with BadBoy circuit???

    I'm using a R123 in my FireFly2, which has the standard BB650. I don't know what the Vf bin of the LED is, but I've never had any problems. I figure if I burn out the circuit I can just buy another from the shoppe, but so far I haven't needed to.

    Where Are the Drop-In Sandwiches ?

    Sweet. I could even see an overall sales increase since some people (like myself) are hesitant to purchase a sandwich that isn't exactly the right color/wattage/converter/etc.

    Where Are the Drop-In Sandwiches ?

    I also like the build-to-order idea. I would be willing to pay a little more and wait a little longer for delivery. In return I'm getting exactly what I want and I don't have to wait for Wayne to build a batch of the module I want.
