The Elephant and the Dragon

I am currently gathering supplies for mounting a XM-L on a Peltier plate and testing it at currents up to 10 amps. I just haven't gotten a chance to make and calibrate and IS yet. My hope is to do the test sometime around January.

Oh that’s smart, I’ve never thought of using a Peltier plate before. I am really interested to see the results of 10 amps, since up to 6.5 amps on the graph it’s still going up. If you can, also test the SST-90, I want to see what’s the maximum you can push it to while it’s being cooled.

But are peltier plates effective at removing a lot of heat fast? I read that it takes a few minutes to cool down to it’s minimum temperature.

I don't plan on doing a SST-90 as the power supply I have access to only goes goes up to 10 amps. (Or something like that) If not peltier plates then dry ice. :D Either should be able to keep the LEDs at sub zero temps.

Well I still look forward to the 10amp sub zero XML, which of course isn’t possible in a normal flashlight host. Maybe if there was a host which had an inbuilt peltier plate in between the pill and heatsink and driver and heatsink - now that would be pretty nice. But I think peltier plates require a ton of energy, so it won’t happen in the near future :stuck_out_tongue:

I'm certainly excited to find out what it can do but don't hold your breath. :) I still have to make the IS and figure out the best way to mount the LED, that along with convince them to lend me the power supply. :D

Here are the last two steps:

Added a copper ring on top of the DRY carrier to route the battery Negative up there.
Also cut the elephant body down about 1/2 inch.

The switch lit up when the light is on:

Group photo of contestants for the up coming beam shots Battle in the Wood III: The Elephants vs. The Foxes:
All are 3x18650 format except FF3. (left to right FF1 35W HID, Elephant FM3H CBT-90 9A, Elephant FM3V CBT-90 15.5A, Elephant Dragon XML U2 6.5A & FF3 40W HID)

I actually measured the lux but I am keeping it secret :slight_smile: until the Elephantr vs. Foxes battle time, but here is a hint, when on Medium mode, it scored 160,000 lux @ 1 meter, can you imagine what’ the lux # on Hi? :crown:

Awesome work Ma_sha!

Thanks :slight_smile:

Ma_sha, your work is simply stunning!! I can't wait to see what that does on high. What is the lens diameter on the Dragon head?

I love your posts. Seriously nice pictures there. And nearly insane lights! Wonderful.

Looking forward to the shootout and the revealing of the score on high! TY for showing this.

Amazing, as usual.

I really like the vandal-proof switch; do you know if it will tolerate 16V ?

Thanks buddy, the Aspheric is about 3” diameter

Thanks.

The number will be revealed at the night of the shoot out, but I have one more light to make before the shootout, the legendary 2000 lumen FM1909 incan, it pulls 6 Amp at 12V. I’ve never seen any lux numbers except everyone that had one appears to have been blown away, I hope it’ll live up to the hype in a 3” turbo head against these led & HID monsters. I’s been ordered :slight_smile:

Fantastic effort ma_sha1. Your really pushing the bounderies here. Looking forward to the shootout.

Thanks, buddy. I don’t know but I think most likely yes, as it’s low amp draw for the glow, it’ll probably just glow brighter.

Thanks!

On high - 300k lux

Wow, amazing!

Holy poopcicles

Thanks Guys,

Still waiting for Five Mega to ship the FM 1909 bulb & another FM3H turbo head….

I have forgot to mention that the led star I used is direct solder copper base ceramic star taken off from Olight SR51.
It looks like it has copper surface contact area 3 time that of the Led-tech de copper star.

Aside from making your own, There are three places one can get XML on copper star, I have tried all three,
this is how I felt about them:

International outdoor: good for 4.5A Thin copper & rather small contact area
Ledtech de: good for 5.5A Thick copper but rather small contact area
SR51 star: good for 6.5A, thin copper but rather large contact area, it’s huge almost 1 inch square

The SR95 star is same technology as the SR51, direct to copper thin & large, almost 2” rectagle

I have almost no flashlights left, except very few must keep including the Darth Vader, finally I managed to de-dome the XML cleanly to increase the lux further:

It came out pretty well, the lux went up from 280klux to 468 Klux, I think it might be worth trying adding a Weiven Collar? I maybe able to get it up to DEFT X level of throw but with a 2x bigger spot, since DEFT-X is XPG2 de-dome , this is based on XML de-dome,
