Re: CQvn P60 - Solid Copper P60 Quad
I've read through every page in here, so I have a pretty good understanding of what host set ups work best for these lights. Still I'd like to draw on everyone's personal experience that may apply. I have a 4 x XPG2 DriverVN2 in 5000k on the way. I want to be able to use the available lumens that it can produce for more than just a WOW light and a larger host is fine with me, i.e 26650. I think I've settled on getting an Oveready Defense Light with the copper Cryos head, but would prefer black for looks. I also have the smaller original black Cryos head with a TL65 (18650) host that I can use as well, both with a Zero Rez switch. My question is this;
Running the 4 x XPG2 emitters, being that they'll be putting out less lumens and I assume less heat, is it really necessary to run it in a BIG Cryos copper head host or would the smaller 18650 set up work just fine? I know the 26650 cell will give me more run time, how much more though I don't know. And is Copper THAT much better in dissipating heat that a standard anodized head... enough difference that is to justify the added weight and expense?
ANY input would be much appreciated.
Thanks in advance guys and gals.

Actually anodized aluminum is BETTER at dissipating heat than copper...but since it has roughly three times the mass for a given volume, it can "soak up" a LOT more heat before the copper gets as hot...so you can typically run it longer than you could with aluminum, if you are judging by the temperature of the exterior of the light. The other thing to consider is what cells you use. If you use a very high-drain cell with very low internal resistance, you will get more lumens, but you'll also generate heat faster. If you use a Keeppower 5200 mAh 26650 instead (for example), you will probably not even notice the difference in brightness, but you will get quite a bit more capacity, and probably won't have to step it down as soon either.

Re: CQvn P60 - Solid Copper P60 Quad
Meaning IMR cells?
Does a higher mAh = higher drain - I'm not versed in this aspect.
So the anodized aluminum vs Copper sounds like it'd be a wash then?

Re: CQvn P60 - Solid Copper P60 Quad
Not really, to all your questions. The metal/air interface is TERRIBLE at conducting heat...so more mass usually means longer effective runtimes before it gets too hot. (If you are running a high power light, unless you have great airflow or very cold temperatures, it will get too hot eventually.) Copper (especially a big Cryos head) will manage the heat better.
There is little correlation between capacity and low internal resistance. The very highest capacity cells are rarely or never the best for high-drain use.
I used the "high-drain" term because there are several types. IMR is a specific chemistry, a subset of high-drain cells. But not all high-drain cells are IMR. The Samsung 25R being one very popular example...it uses a different chemistry (INR) and I'm sure there are other types. There are also "hybrid" cells like the NCR18650BD, which have most of the capacity of standard cells, but can deliver a fairly high current also.

There's a lot of variables mentioned above and some of it can be misinterpreted.
IMR is a lithium battery type. They are generally considered a battery type that tolerates a high current drain by using a chemical makeup that has a relatively low resistance.
FOR A GIVEN SIZE, the maximum capacitance chemistry make up does not usually have the lowest resistance for energy draw and usually does not tolerate high amp draws.
E.g
18650 IMR vs 18650 LiPo
mAh - is a battery's capacitance of energy. It's short for milliamp hours.
Your larger batteries will hold larger amounts of charge.
Thermal conductivity as stated above dashes on several aspects of pulling heat away. There's surface to air ratio, volume mass transfer etc that goes beyond my meager physics.
Gist:
copper pulls heat better than aluminum.
But copper also happens to be denser and heavier.

Thanks all for the explanations. I should know this all, but half way through my EE degree I went into medicine instead. Go figure. I'm familiar with the IMR cell and have used them for my past Oveready triples. I just haven't dabbled in the larger cells and am still trying to grasp the whole "some cells allow for Max brightness and some for Max runtime" deal. I think with the above help, I've settled on an Oveready Defense Light using a 26650. I plan to try out the Efest purple 3500 purple for max light and the Keepower black 5200 ? Cell for runtime. Any real perceivable brightness between the two really?
had this quad for maybe a month now. when i first got it i put in my panasonic 3400s and wasnt all that impressed. i put it away and there it sat until yesterday. i finally received some samsung 25rs and now this is one smoking light cannot put it down hahaha :D

Where is that smoke coming from????
its not from the light ;) just goofing around :)
though it does get hot with the high drain batts fully charged on turbo.
so hot that the mcclicky switch melted. i replaced it with a switch from an s3 convoy that i ruined while attempting to do a dedome and im back in business. fit nicely into the l2t tailcap. even did a resistance mod on it.
feeling pleased with myself and my limited skills
Yes sir
I have DriverVN that can handle 6V
