Kenneth07ex,
If you can have a month or so of patience, I am working on a group buy for a solid copper Astrolux A01 HERE it will be uncoated and price right now is only $20. With a Nichia 4000K 219B-V1 emitter and three modes, it should be a great light for one that is not “needed”, but only wanted on the keychain.
One nice thing about copper and some brass alloys, they have antimicrobial effects …
That’s a nice looking light, I’d definitely be interested in a copper version for $20. Is the mode spacing still the same?
Yes, the modes are the ML, low, high and after two cycles through, a strobe. The idea was for a copper version with no tweaks to the internals to slow development. The stock one is pretty good, though some do not like the ML level as it is very low and sub lumen. Personally, I like the level spacing, I would rather have the modes too far apart than too close together. The 4000K emitter is NW to WW level and very easy on the eyes…
Sweet collection!
What is the one that is 3rd from the left in the bottom picture? It looks like it has a wicked font for the logo!
Reylight Limited Edition Lumintop Tool Copper AAA Flashlight with Nichia 219B
ReyLight Copper Lumintop Tool with Nichia 219b. Modes are 1/18/80 lumen, in that order. It is NLA, but I have a brand new one sealed in foil, PM me if interested.
Lumintop still makes the Copper Tool with Nichia 219b. Modes are 18/3/80, in that order.
fwiw, the Olight CU is not copper, its brass coated with Gold Colored Titanium Particle Deposition Vapor. It does not tarnish, and does not have the germicidal properties of Copper.
fwiw, copper and brass, including the knurling, can easily be cleaned with a vinegar soak (or ketchup)

Copper is much better at conducting heat as well as electricity, than Brass.
Of the lights pictured, the Tool and Prometheus Beta offer the Nichia LED. The Tool has NoPWM, I recommend it.
Another light with a Nichia, with NoPWM is the Lumintop Copper Worm with 18/3/80 lumens.
I like to use the head of my Worm on a Maratac, (the maratac head does not work on the worm, but I find the worm body too heavy, so I only bought it to get the Nichia head)
or at times on a Titanium Thrunite
neither Maratac, nor Thrunite offer the Nichia LED
The ReyLight Tool head also fits the Copper Maratac, and both lights work with the heads swapped (You can see the Maratac head is Cool White, while the Copper Tool is Neutral White and High CRI):
Thanks for taking the time for the explanations.
Wicked lights!
If you are not too keen on patina or smell’s, or the weight of copper/brass, check out this deal: Thrunite Ti
Edited the link. Sorry :person_facepalming:
Ooh, nice! Some of them look almost wooden the way they aged…
Like the Kronos. Reminds me a bit of a copper Convoy M1. (Well, sort of.)
Unfortunately, I gotta keep my lights in holsters. No way could I get away with pocketting anything copper or brass. Anything I pocket-carry after a while ends up looking like bobofett’s helmet.
