The Maratac AAA "Cu"

[fyrstormer]

A light like this needs no introduction. There are plenty of brass lights floating around, but I've never seen a copper light before, so I told County Comm to send me a couple, so I can decide if I like them or not.

There's already a review on CPF, so instead of writing a new one, here's a link to the original: http://www.candlepowerforums.com/vb/showthread.php?t=240639

Pics!

Is it a copper body or simply copper coloured?

If it's copper, does it make your hands smell from holding it?

I remember another CPF'er posting that yes, it does make your hands smell like copper. It'll tarnish as well, so get out your toothpaste and toothbrush once in a while and give it a good scrubbin'.

It's copper through and through; it weighs 2.5x as much as the aluminum version (all of an ounce, ye gods!). It only smells like pennies ever so slightly right now, because the finish is still freshly polished. I'm sure it will smell more like loose change once the surface layer degrades a bit.

Actually, I take it back, there ARE a couple of notable differences between this one and the original aluminum version:

1. the PWM is much higher-frequency;
2. the modes are Low/Medium/High instead of Medium/Low/High.

Other than that, it's the same.

For some reason I can't adequately explain, I don't mind tarnish on copper nearly as much as tarnish on brass. Something to do with the whitish film that forms on brass as it tarnishes, which copper doesn't do because it's not alloyed with any other metals.

copper is almost never used pure, and is almost always alloyed with other metals.

Fine, then it's present in a large-enough percentage that the effect of the other metals on the nature of the oxide layer is insignificant compared to, for example, brass.

 

[Ragiska]

alloys don't necessarily have even remotely similar properties of it's constituent metals. that's the whole point of alloys, they are completely DIFFERENT materials, with unique properties.

example: brass is mostly copper too

 

[fyrstormer]

Of course they have similar properties. Atomic bonding and chemical reactivity are primarily governed by interactions in the outermost electron shell, hence why metals in the same column in the Periodic Table have similar chemical properties. In alloys, electrons are constantly bouncing around from one atom to the next, so the valence of each atom in the alloy is best described as a weighted average of the natural valences of the pure constituent metals.

Thanks for derailing the thread, btw. The tiny amounts of dopants that may or may not be present in the body of my Maratac AAA Cu are irrelevant to the original point of the thread and you know it.

Ragista is good for derailing threads, this is true.

I know this was a serious post but it made me laugh nonetheless. :twothumbs

 

[waddup]

I want one.

me too, i WILL have one.:twothumbs

i dont care about the exact chemistry of the atoms of the metal/s bonding properties.


sure is purdy

Nice pics, but how do you like using it? Does it feel weird in your hand?

If you've got $600, Photon Fanatic is making an AAA Killer in sterling silver...

 

[Flying Turtle]

Thanks for the pics and info, fyrstormer. This is the first I've heard that the PWM frequency is higher in this light.

A very needed improvement.

$38? Doable. Anybody use a 10440 in one of these? Does it toast the LED? L-M-H is good with 10440 if it doesn't ruin the flashlight.

 

[fyrstormer]

They recommend not using 10440s in it. Some have, supposedly with acceptable results, but considering the driver in this version is at least slightly different than in the original version, someone would need to test the new driver to make sure it isn't more susceptible to damage than the original one.

I like using it, and thus far the tarnish layer is just bright pink, not the dark matte coating brass develops. I like it.

 

[recDNA]

Only one website carries Maratac now?

 

[nbp]

To be honest I had no real desire at all to get any of the alu Maratac lights. I already have an LD01 in SS that I love and keeps on ticking for me. HOWEVER, there is something very cool about this all copper light and I really like the look of it. Plus I like a light with a little heft to it, makes it feel sturdier. I could be persuaded to get one of these I think. I'll be watching the MP for the first round of them to go up for sale after some decide they don't like them.

Here's a pic showing patina changes over the years, which of course would be much different for an item getting handled as our lights will, but it would be nice to see you buy enough of them to let them age in different environments and preserve them over the centuries for the rest of us to enjoy!
