Looking for a copper AA or AAA light to replace my families ancient Arc-AAA's.
If you want a single mode 10 lumen light that is durable like the Arc, maybe a Fenix E01? (not copper)
Im a big fan of copper AAA lights. Curious what interests you about copper?
be warned, copper is heavy, for my keychain, too heavy
my copper Maratac 40 grams with battery, my Fenix E01 is 26 grams
in copper, I suggest you consider going to an AAA copper light with a Nichia. (I vote Tool)
in AA copper, Olight has some options, but only Low CRI, and they are quite heavy, compared to Aluminum..
these are 3 mode lights, not inexpensive:
Maratac Copper is cool white, low CRI. My favorite form factor, but least favorite LED (Im not into Low CRI). Supposedly the first mode is 40 lumens (I have not verified)
Lumintop Copper Worm with Nichia is High CRI. Overly heavy, I dont use the body. I sometimes put the head on my Maratac. First mode is about 20 lumens
Lumintop Copper Tool with Nichia is High CRI. This is imho the ultimate current production copper AAA available with a High CRI LED. I use the head of the Tool on my Maratac body (to get a Nichia with High CRI). First mode is about 20 lumens
stock maratac on left, stock Worm w Nichia middle, Custom modification to Warm LED on right
the beams in the same order
Here are a couple tools also, the Nichia Tool heads are swapped with the Maratacs. I dont carry the Tools, they live in my cars, I pocket carry Maratacs
thanks for the excuse to post one of my favorite pics.. worm head w Nichia, on Maratac body
while on the subject of copper lights for keychain, just for fun
consider an
Astrolux M03, they are inexpensive atm. Its more of a novelty toy, they are in no way a cockroach light like the Fenix E01 and the Arc-AAA. otoh, the Astrolux is half the size, and half the weight, of a Maratac.
