Your right! I was thinking of buying the rechargeable version the R7 rebel with hollow injectable resin reeds. Sweet light! Or the Reedlight Mark 4 which comes with the large diameter bright reed which throws full flood at the 4 lumen setting.

Placing the reed torches aside for a moment...

My earlier assertion was only based on a hunch, and it was bugging me that I might be wrong. So I did some research, and thanks to one of the fine people over at Candlepowerforums it seems I was right after all.

In max brightness mode, Mr Lipton's Olight T-15 should provide about 52 minutes of light on a Duracell AA alkaline battery. But if he were to use a rechargeable Duracell 2650 mAh NiMH AA battery, it should provide a full 2 hours of light. Big difference! (Times are based on how long it takes for the light to dim to 50% of its original intensity.)

This information and more (comparing several similar flashlights) can be found here

Even though it's twice as efficient, I imagine Mr Lipton might counter by saying he feels any newfangled NiMH battery would only be "half as reliable."

wow, based on the 330 hours of caving I did last year, I would have thrown over 300 alkaline batteries using that setup. Instead of, you know, zero with my Stenlight.

But, you know, like Mr. Lipton says, that's trivial, and pollution on a small scale doesn't matter...
I like how he seems to find the idea of recycling bottles and cans preposterous and suggests we "get real."

I find dragging burning tires with a chain through the cave the best source of light. They last a long time. Usually the next trip in, we don't see many bats though...............

I wonder if Mr. Lipton knows that you can buy an adapter to use AAs with the sten as an option, I know the beauty of the sten is the battery tech. , but if you prefer you can use AAs also.I do not yet own a sten ( I am in saving mode for one) but when I get one I will get the adapter also so if for some freak reason the rechargeable failed I could go to the AAs that I carry anyway for my backup lights.I cave a couple times a month in the winter time only and so far AAs have served me well with the apex and duo leds but would love to have the new rebel sten.Also the sten batteries are light and it is easy to carry two on any trip.I have been caving for 28 years and cannot believe how fast light tech has advanced in the last several years.

You guys are all just jealous that your setup doesn't have a super-old-school helmet with awkward-looking, easily ceiling-smacked flashlight strapped to the top of it like Mr Lipton's.
