My Latest Insane Project

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.

+1

:D

Actually, SF does have such switch: http://solarforceflashlight-sales.com/product_detail.php?t=LF&s=41&id=198&sname=tactical&xpage=1&sh=1

Btw scaru, so far the AW IMR18650 still seems to be the way to go. We have some promising cells from Samsung and Sanyo coming from the far east, but that might take a while.

LG and Panasonic are out of this contest, no cells with according specs available and Sony have been tested and those are inferior.

Oh, and of course I will modify spring and switch. Using flashlights without any springs gives me a bad feeling about squishing them..

Thanks Nightcrawl. The S7 does have a spring and has a decent amount of resistance.

Part of the reason I'm obsessing over this so much is when I'm going to use 12 gauge wire within the drop in, I might as well reduce resistance everywhere else.

This is a knife switch, you said you wanted a switch to handle 21a, I suggest what you want is a switch that fits a solarforce host that handles 21a :bigsmile: :stuck_out_tongue: J) 0:)

Sorry, limey humour….

Ah…ahem.This has already been built and sold both in triple and Quad mule configurations.
Link? Search should be fairly easy…The players do reside at CPF

But those are triple and quad. This is 7. Huge difference! I say if you can do it go for it. :slight_smile:

In XM-L? Really? I looked around and can't seem to find any, if you can find one I'd be interested to see a link.

Over at CPF, there have been some conversations about reducing the forward voltage of LED’s by shocking them with high current pulses. I believe it was a SST-90 though.

Can’t wait to see how this project works out! :wink:
