no idea, I didn’t even notice it says “new copper + titanium”….where lol
Copper heads.
Thanks for the update Freeme! I’ll order an E07 in clear anodization with XP-L HI 5000K from this second batch. As soon as I get it into my hands I will report about my observations regarding quality improvements. Or maybe I should wait for these nice copper heads? :heart_eyes:
I believe the copper heads are reserved for the titanium body for the first batch. If you guys would like to have copper with aluminium combi, do express your interest below. It is probably a good idea to state roughly how much more are you willing to pay for copper head option.
How much for the copper + titanium?
I would like to have copper with aluminium combi.
Thanks
I’d like copper + copper.
big heavy Cu head, tiny lightweight Ti body, can’t wait to hear the complaints about it…
Me, I want a complete recycled copper head, I mean ff is not Astrolux per se but it might be a $10 premium more or less normally, I don’t know, and more with a titanium body combo, but more importantly I want to know that he has fixed all of his other issues, there’s a whole list. He doesn’t respond to us but markets us special metals; it’s a bit of a conundrum.
2x+.
My 219B version started acting weird. Click turn on and it blinks one to a high mode and dims to moonlight. If I try to ramp it up, it will also drop back down to moonlight. Sometimes clicking on the button have no effect at all. Cannot even turn it off.
Jacky responded in three days and said he will send me a new one. 
I will buy the copper one so he can send them together.
Clad to hear that.
one clear aluminium body with copper head please:-)
Jens
Yes, clear aluminium body with copper head
I would like all copper for the best dissipation of heat. Thank you. Or aluminum and copper.
That’s what I used to think too but it’ll add significant weight for not much additional heat shedding. The majority of the heat shedding is done in the head so copper head makes good sense but body not that much. Also copper will sink heat so fast, it will make it uncomfortable for your hands to hold if the body is copper too. I’m not against full copper body but just copper head seems good enough.
Interested in copper
SKV89: I don’t think that copper head would make a huge difference. It’s not about better, it about pretty 
Actually it does make a huge difference in turbo runtime. I compared S2+ copper with S2+ aluminum using same pill, the copper can maintain the turbo much longer, maybe twice as long but it also takes much longer to cool back down. Copper also helps with heat shedding since heat transfers to the surface faster but the difference it makes is probably not too significant.
Seems like the copper would cool down faster than the aluminum.
it’s more conductive, not more emissive, but it’s going to do a better job of extending turbo with a thermal cutoff, it always does
