RC-C3 Cree LED Flashlight Gray (1.3V~4V CR123A) what does it mean? A cr123 battery isn't going to run down to 1.3v and the circuit provide a boost - and a AA doesn't look like it's going to fit.
1.3V~4V CR123A what does it mean?

Probably means it can run on CR123As or RCR123As. In fact I have 2 of these, one Cree and one Lux III, both running on 1x RCR123A (3.7v).

Yeah but a cr123 isn't supposed to run down to 1.3v.

What's the problem? It implies that the light will run on 1.3v in the same way a 3.0v-9v will run on one cr123.
Then it should say: 3v-4.2v

Hmmmm...... seems to me this merely states that the circuit will support voltages from 1.3V-4V, and that it comes standard with a battery tube that fits CR123 batteries.
Possibly, if somebody had a 1xAA battery tube that happened to fit this light... they would be able to run it that way also.... a nice thing to know.
My only hesitation would be the upper limit of 4 volts, as it seems that most RCR123 batteries come off the charger at closer to 4.2 V, but maybe that's not a problem with this light.

I guess what I'm trying to understand is - my light runs on rcr123 but probably won't run on 1.3 volts. Since this light can, is there some kind of boost circuit to enable it?
RCR123 can be 3v or 3.7v.
The 3.7v ones will charge to 4.2v but their resting voltage is about 3.8v only. So they should be OK provided they are not used in this light straight off the charger. The extra 0.2v should not harm the light as it is going to drop very soon after turning on.
The 3.0v ones are OK because they only charge up to 3.6v.
For such technical matters I suggest we ask SilverFox. He is the expert.
BTW, there is a thread for the benefits of UK members in The Cafe. Do take a look if you are based in the UK.

Thanks Windscale - though I already know about the 123 batteries. I have two flashlights - one using AW123 and the other a single cell unprotected.
What is confusing me is the stated voltage range and DX not supplying any information beyond that.
***edit - oh oops, you weren't even responding to me. See how I am?

With many of the lights I've seen -when a light accepts other cells, it's usually for 2AA which is 3V of course. I've never seen a 1AA tube for a 123 cell light.
