CR123 x 3 = 2 x AA in length

[abvidledUK]

For a while, I had replaced the incan bulb in cheapy (69p) AA torches with SMJLEDs.

The 2xAA batteries always were a loose fit.

Today, brainwave.

3xCR123's fit ok.

Experimented with CR123 spacer(s), and found that 3.0v RCR123's work very well with 2.4v & 4.8v incans, and appropriate (AW) spacers.

New lease of life for torches that I was going to throw after removing SMJLED's !

Yes, they are brighter than with 2xAA's, I've not yet had courage to try 3.6v RCR123's.

I have no doubt the bulb life will be reduced too.

of course they are the same length.

Since 123 stands for one 2/3s of AA length. Much as CR2 is 1/2 the AA length.

But you are very lucky to find a AA flashlight that will house the CR123 width.

I tried to do the sa,e qith a MiniMag and 4 CR2 but no luck, the light needs about a 1,5 mm boring.

Have a good luck with your "Hotwirings", kostas

hmm sounds interesting 4*cr2's in a minimag big output in a small package?

what's the mah rating on a cr2 anyway?

 

[speederino]

CR2's run about 600-700mah. At one point I recall a few of us taking to Ledean about making some 2xCR2 cutdown minimags for the Twintask 2L bulb...then the Auroralite TL-3 mag mod hit and pretty much cornered the market on wicked bright minimag mods.

if CR123s fit well, maybe 2x17500s would fit?

if this is a PR bulb we are talking about- what about a 5 cell xenon mag bulb on a pair of 17500s or 3 CR123 primaries.... or try to find a bulb rated like 9.6V and run it on 3xRCR123s, lol. (not sure where this exsists, but maybe it does somewhere)

Actually, in the dark little noticeable difference to output using RCR's cf AA's, so not worth the trouble in my mind.

I'll stick to my LED's

You could always use L92s or 14500s...
