My Latest Insane Project

People always said a P60 couldn’t handle 3 XM-Ls. It turns out it can. I was (and still am) pretty happy with my triple drop in, but I feel like there is still wasted space.

I recently heard that Nightcrawl is making a quad XM-L P60, which is the limit of how many LEDs can fit on a board and still have optics. Naturally I still want to have the most XM-Ls in a P60, so I was rather annoyed with Nightcrawl. He would have the one with the most XM-Ls, then I realized.

Who needs optics. :evil:

So my question is, who can make me a heatsink out of copper for P60s that would have holes spaced correctly for this. (Mattaus's heatsinks wouldn't work)

As usual, special thanks to PilotPTK for his amazing work on this. Now I can have some nice thick wires going to the LED. :D

Oh, so you dont have access to a grandpa with a lathe and huge chunks of copper in the basement? Thats really gotta suck! :D

I'm no mule fan, so go at it. :P

More may or may not be better, but it sure is more. I think your into the realm of active cooling or toastinator fins.

that’s AWESOME

Someone else will put one in the middle too and beat you. Might as well go for seven and get it over with.

??? I already have 7 on it.

SolarForce M3 head might make a good start. Bigger lense, more room to shove copper in. Driver in the normal P60 spot sitting under a giant chunk of copper with the Leds sitting at the top of the host. Lenses resting over the Leds filling up the rest of the M3 assembly, so no mulehead needed.

I think it was more like people said that a P60 couldn't handle the kind of current it would take to drive 3 XML to their maximum.

Have you been able to get your triple XML to draw more than 6 amps yet?

No, I don't like the M3 since it is not a standard P60.

Also, my search for batteries is over.

Hypothetically I cant get a minute or two of run time before it runs out of batteries. Of course some basic calculations show it might reach 5000+ lumens.

Your going to reinvent the flashbulb with those runtimes and lumens.

Yes, but not through the switch. That is why I'm installing a zero-res switch. ;)

What's the max current draw that you've been able to get?

8 amps from and IMR battery straight the body of the drop in. If I do it through the body and the spring it is a bit lower. Even lower if through the tailcap.

I can tell you that 20 amps is obtainable (hypothetically) using a zero res switch and no springs.

ZeroRez? One of these overpriced oveready thingys?

I'm pretty sure solarforce had a similar switch once..

What is this?

Yep, one of those overpriced things. ;) Afaik Solarforce never made one.

As for why I got it, do you really think any spring can handle 21 amps?

Yes. :)

Wait, so you expect a normal conventional switch to handle 21 amps? Good luck. :P

you said any spring, not any normal conventional switch :stuck_out_tongue:

Ok, fair enough. In my limited testing even the fancy gold plated springs can only do 15 or so amps.
