I only have rechargable & these don't comply with your requirements.

But we are very happy with our Olight USB charging torches. They go for a very long time if you don't have them on full brightness. I bought an extra battery for each but have never had to use it, I think about 4 years since purchacing. The S30R is slow to charge so we don't take it camping.

The head torch (H1R) are a warm white which is easier on the eyes.

Olight do a AA torch.

Hi Mike,

I here you.

However Mike would you take a look at Roybi LED torch H/L beam.This one can run off a cigarette power point or battery. Will run 4-5 hours on a 5amp rechargeable battery. Will recharge off a generator 1 Hour recharge. You can charge six batteries if you happen to use six./ and run off the generator without the battery connected.For spotting wildlife Fantastic IMO.

Or the 25w Roybi lamp.again turns night into day.And runs as above. ADD a SIX YEAR warranty to both. Hard to beat.

 We run Roybi everything except for our honda Ei2000.

WE can do this as I used everything in my working past.

At best, take a look.

Some brands have unregulated voltage so as the batteries go flat the light gets dimmer. This has advantages & disadvantages.

Candlepowerforums has a lot of information.

I've been using a Korr for the last 6 years, well built was expensive when i bought it (~$70) but has lasted well gives good light and still on original recharging battery.

Cheers

Richard
