Should be 22AWG.

How many lumens could you get with only 3 amps driving this?

You know it’s not clear, but 10 amps is really great

At 4.0v and a distance of less than 3 inches, 22AWG will carry close to 20A, assuming 5% loss

Bort, that was an attempt at humor, about cooling fins: the link is to http://www.rayguns-r-us.com/

It was a rare non attempt at humour, it just looks futuristic, thanks for the link, i thought it might have been the gun marvin the martian used.

You don't need 18 AWG wires, the 22 AWG are just fine for 9A-10A.  What is your current measuring setup?  If you are using multimeter probes then you have a huge problem right there.

As rmm alluded to, the problem is in the meter leads you are using. If you measure the 6 amps, and then touch the leads together circumventing the multimeter, and the light gets brighter, there’s your other 4 amps.

Do not use unbranded batteries ever.

If you want max lumens, unprotected is a must.

And a high drain battery is preferred, such as the 18650GA or a 30Q

Thermal pastes only work where the layer is very thin, like microscopically thin. In thicker layers it acts as an insulator not much better than air. To get the thin layers required usually means very flat highly-finished surfaces and high clamp loads, things that are usually not possible in most flashlight parts other than like between MCPCB & pill top, pill flange to head surfaces, or rather tight press-fit pills.

Okay, wait. You’re saying that thermal paste, something that is supposedly made for helping to conduct heat between two surfaces, is just barely better at conducting heat than air? That is hard for me to understand. According to Engineering Toolbox, even Styrofoam (made to NOT conduct heat) conducts heat better than air. Plain ole Epoxy has a thermal conductivity that is almost 15 times that of air. Insulating brick (didn’t know that existed) conducts heat at a rate 6.25 times that of air. Yes, these are still relatively tiny amounts, because the only thing that air conducts heat better than is a vacuum. But, we’re talking about thermal paste. It should be pretty good, I’d think, at doing what it was made for – especially compared to leaving the air void that would be there if the paste wasn’t! edit: to clarify, there are several gases on the list that are less heat conductive than the air we breathe, but I call them all ‘air’ for the purpose of these comparisons.

Yes, that’s exactly what I’m saying. Your ideal insulator, styrofoam, could very well be a very good conductor at a thickness of 1-3 microns.

edit: And this is why these reference charts are misleading at best. You have to know how to interpret the data as it applies to a specific situation, and if you don’t know how to do that, you’ll think you understand something you really don’t.

comfy, you say “And it definitely won’t help between the other parts of the threads that aren’t physically touching.”
but David say it will help,
then you say “Yes, that’s exactly what I’m saying.”
got me confuesd :-/

i mean, how can air be any better then thermal past? even if it is more then 1-3 microns.
i do how ever agree that you need to know how to apllay it.

Indeed. Triple “custom” P60 for $99.99 as well (I obviously did not build that driver!)

You can get a bit more than 3000 from the XP-L HI, while the 219C can almost reach 3000 OTF with a single 18650 due to the low vF, but it quickly settles down to 2500 or less.

question-how will fet driver blf working with the triple xpl?the same function? cos as i know,there is turbo timer.30 seconds or so.how will it work in this upgrade?
also-do we need longer wires,when we will use the spacer?
also-do we need cut the base of the carclo optic? cos they looks little bit longer,then we need…iam not yet sure..

for the convoy hosts you need longer wires,the optic dont need to be cut.the fet driver will work as before but expect on high to get near 10amps if you have good battery.
