Is there an 18650 book light?

Curious if I can find a book light(ya know, clips on to the back of a book with an adjustable goose-neck lamp for reading in bed) that runs on an 18650 battery. They are common in AA, AAA, and proprietary batteries but I like to use my stable of 18650’s whenever possible. Didn’t see any on Amazon. Anybody ever see one?

I have never seen one, but then i wasn’t looking, either.
It seems like overkill, one AA could last for 100 hours.

I’m sure you’re right but then….I’m a BLF member. No such thing as too many lumens or too many mah. :smiley:

I gave up ages ago and just use a headlamp.

Now I just got the Nitecore NU25 and I have to say that the little “high CRI” light on it is amazingly pleasant to use as a reading light and the headlamp itself is so light I actually forgot I was wearing it last night.
