Need Help: UK 2AAA eLED

[CCW]

Anybody tried this light with new Lithium AAA batteries?

I do not have the light yet, so I emailed the question to UK, and they replied promptly stating:
1. Lithium batteries were not tested in the light yet.
2. Lithium batteries are not approved for use in hazardous applications.

I understand the point 2, and I am not planning to use them in such application. I just wanted to know if the electronics will handle the increased initial voltage of Lithium batteries without damaging itself. Please help...

TIA.

Causes no problem whatsoever. The light output will be about 15-20% brighter also.

it has a simple boost circuit I think like the brinkmann and isn't overdriven at all so I would guess it would be just fine as a lot of lights overdrive LEDs on purpose. On nimh it underdrives the LED somewhat. But think about it... unless you need the lighter weight and increased brightness/runtime it already runs for a long time off generic alkalines. I would probably run close to 30 hours off of lithiums you may forget it is battery powered LOL.

Thank you for infos.

I was planning to use it as an emergency light, and leave one in a car. Lithium would be a better choice, I thought.

I would recommend something a little brighter as a primary emergency light other than this little light. It is quite dim and even lithium batteries wouldn't make up for it only having one underdriven LED. I would recommend something like a UK4AA eled as emergency light and this light as something to EDC or put in places where you don't have any room for a bigger light. I EDC this light myself using nimh and it is very useful but has very little spill so if the spot isn't on it you cannot see it. I myself would prefer something along the line of 4-10 overdriven 5mm LEDs or a luxeon when trying to do something like auto repair etc, although the UK2AAA eled would work it is woefully dim compared to even a cheap 2D flashlight.
