@DX XM-L's on copper stars.

There's some debate on DX as to these being genuinly copper, but it looks about right to me given the effect a finger print has had on the surface.

At $11.90 theres no premium being paid really, so no loss if it turns out not to be.

Maybe it's rusty?

yea i started that discussion

Hmm, It does kind of look like it's a very thin Alu board on top of a copper one in this photo if you look at the bottom edge, but it could just be catching the light funny as that would be the edge attached to the next star.

Knowing DX, it probably isnt copper... but you never know. According to users of other custom builds, the ceramic package of the XM-L has proven to conduct heat very well to aluminum while being driven hard, and there likely wouldnt be any significant advantages if it were copper mounted.

There would be an advantage from using copper ... If it is copper ?

What's the point... never gonna ship them anyway or HKP will lose 'em.

Can you tell I've had it with overseas?

Rich

it just takes a really long time, and patients. i have YET to have a lost package from our flashlight vendors overseas.

however vendors for car parts are not so reliable... esp off ebay lol

I just had an email from DX saying that about half of the things a ordered almost 4weeks ago have been dispatched.

So I might have all of them by about ooh say August

The ones with aluminum board says 5g while the ones with rust colored boards says 3g, cannot trust the specs but copper is supposed to be heavier than aluminum.

^smaller diameter board

21mm vs 18mm

Back to deep breaths.. come on now back away from that ledge ..you have lots and lots of lights ...there was a time not so long ago that people used trade routes and stuff from the orient looked like spices and odd perfume ,maybe a gem or two ..lights were whale oil and ..smelled like ....whale ..life is good smile and rub the buddhas belly button Tongue out

This yoga thing ain't working for ya
