Hi CPF!

<font color="green"> I need your help! </font>

Here is the case:
I'll bee attending an army curse with excessive light restrictions. The only light allowed is the Mini Mag light. To get the best out of this situation I am looking at the Tektite LT-1 LED (it looks similar to the original led).

Here is the problem:
The LT-1 is only specified for 3V and the L91 I normally use (with NewBeam) is 3,4V.
Can I use batterystations L-AA or is a rechargeable battery better?

This is what I need:

1: Compatibility
2: Reliability
3: Long burn time
4: Cold weather tolerant
(Price is of no concern)

Regards

Commander

will you be around a ability to charge it?
just HOW cold ?

i think i would go with a lithium, long lasting, works in all kindsa weather, and not rechargable. no fuss no muss, be there when you needed it. especially if you like demolitions :)

what kind of run time VS Light output do you desire?

There are some great posts by silverfox above with test results for exactly what you are asking. - Alkaline Shoot out and rechargeable shoot out.

In quick overview terms
- All of the 2 x AA setups will run 2.5 - 3 volts under load
- At the current draws you are looking at (less than 1 amp), the L91 AA cells will be the best performing for run time under your stated conditions.

You could always be sneaky and put a resistor in the tailcap to drop any excess voltage that lithium AAs would put out. It could be made to be removable also. I *think* there are also some resistors switch tailcaps out there you can buy that fit mags also.
