Will they ever make a UK 2AA LED ???

I hadnt even realized there was a 2AA incan UK light before.
But came across this today...

I like the 4AA LEDs alot, not very bright, but great runtime, and regulation.
I use the 4AA as a caving backup light,
but due to it not being very bright for its size, I dont use it much as a primary light.
But if they were to make a 2AA version, that would make a much better brightness to size ratio.

Anyone hear of any plans?
I assume the 4AA led head will not work on the 2AA body,
do to the lower voltage.

The 4aa head works on the 2L body, if that helps. Someone measured the runtime of the 4aa eLED head on the 2L body as about 8 hours.

Paulr,

thanks for the info!
Do you know if the 4AA head was as bright on the 2AA?
I am guessing no, since the runtime is that long.

~John

The 2L runs on 2 r123A batteries, not AA.

The last I knew, BrightGuy was selling the 4AA LED heads, alone, as an accessory to the 2L.

The 2L uses two CR123A's and is about the size of a Surefire E2e, a little thicker but a tad shorter. It weighs less because it's plastic. Nice little light.

oops, i see now, you are talking about a different body.

I like to stick with AA cells for my outdoor gear, makes it interchangable with my other items.

Thanks Empath,
but I would be more interested in buying just the 2AA body

~John

I just put two dummy batteries in my 4AA eLed. It produces about two lumens, not quite as bright as a Dorcy 1AAA.

Thanks alot Nikon !

I expected that
Well, guess I will just have to hope they come out with a 2AA LED

~John

It may work with two li ion AAs or two lithium AAs pulled from a duracell crv3 pack.

I have been looking at the 2 AA body for some time wondering if you could use 2 14500 Li-Ion AA's with the LED head, anybody know?

Using 2x14500 could be a little dangerous because it would be 8.4v when fully charged. You could ask UK if that's safe. But if you want to run the eLED head on li ion rechargeables in a compact body, you might try a single 17650 in a 2L body. I guess you could also try four 1/2AA NiMH cells in the 2AA body.

I'd like if they made a 2AA version of this light but it would have to be a new circuit with a boost converter. The current version is a buck converter which is one thing that makes its flat regulation so simple to accomplish.

hmmm, i didnt even think about 14500s oo:
That is a good option, if it can handle the higher voltage.

im tempted to try a couple in my 4AA UK, with a couple spacers,
but i would hate to fry it

~John

I talked with UK tech (nice people) and they didn't know at this time if the LED module would handle the voltage of 2x14500 cells but would let me know if they could find out.

jtice, using 14500's in your situation (i.e. because you're trying to standardize on AA's for caving) is just about the craziest thing I can think of. Do you -really- want to be fumbling around in a pitch dark cave with two kinds of AA-sized batteries of radically different voltages, so you can blow something up by putting in the wrong cells? (Put those 14500's in your AA-using $1000 digicam and you can kiss it goodbye). The idea of standardizing on AA's is interoperability of cells between different pieces of equipment. If you've got multiple kinds of cells that don't interoperate, having them the same physical size is a DIS-advantage.

paulr,

Using the 14500s wasnt really for the caving aspect,
I would rather see a real 2AA led version,
but around the house, ATV, glove box, etc, I thought the 14500 solution would be "ok".

~John

Hmm, maybe. But around the house/glovebox/ATV where weight isn't a big issue, you may as well just use four AA's. Me, I'm leery of 14500's even around the house because of the possibility of damaging something that expects AA's.

thats true Paul,

heh, I see you just sold a UK 4AA led, that I just missed

Hearing that they are discontinuing them, I will be picking up one or two more soon.

~John

I guess paulr's comment about the buck vs. boost circuit makes sense as to why UK hasn't released a light in the 2AA form factor. I like the look/size of the 2AA version and it is the only light I can think of with a side by side configuration (besides from eternalights which use 3 cells). As it seems that boost circuits are getting better and cheaper these days, maybe UK will eventually update this light with an underdriven luxeon as well? I hope so .

They're being discontinued? Oh well. Heh, good thing I sold that one before I found out, or else I would have held onto it and had yet another flashlight I don't need .
