Water Cooled LED Flashlight :)

If you build another one like this, important safety note - don’t cross the streams!

Add some ice, much higher heat of fusion :wink:

for those lights way beyond 30000 lumens I did in the past talk about watercooling with PC watercooling components and battery in a backpack

Woot! I knew I was sure to win a prize of some kind :slight_smile:

Sounds reasonable. I would be out of battery before I was out of cool…

I’ll let them know. Most day’s I’d like to fire them :student:

It really is a lot of fun. No overly practical, but fun!

Love your videos. I’ve said it before, you have a great sense of humor

Now I know who I’m gonna call

The one thing I learned is that any unexpected problems can be solved with 2 part epoxy.

Funny creative and informative simultaneously. Win.

LoLoLoLoLoL vestureofblood! There are some inexpensive and good waterblocks you could have used, with the MCPCB installed over.

I understand that was a sort of quick “let's see how it goes” project, though.

Did I read someone claiming “up to 18A (2S) for the newer XHP70.2s on an L6” in the video comments? Freakin' seriously? Can you make some scrambled eggs with it?

YOU ARE A NUT!

So fun….!

Very cool build, you kept my attention, kind of mod I like to see. Could see this easily being used on a scuba light, two opening and a pump, no tank needed.

Cool demonstration of how high power leds can run stable at these powers, and a fun video to watch :slight_smile:

Well done, fun project :slight_smile:

The bit at the end where you were running around with that thing was priceless :slight_smile:

Thanks for posting (and providing proper captions) :+1:

Yeah me too!

Epoxy FTW!

I have some of the 70.2s on the way. I will do a test with them once they land.

:slight_smile:

Very Nice—That light is almost as big as the BLF GT—— JK
Did the water eventually get hot in the jar

Not really. Probly the longest I have run it was 10 minute bursts. This took room temp water up a few degrees, but not even what I would call warm.

completely “cool” project, thanks for sharing :slight_smile:

That Brass tube is pulling lots of heat also—Have you tried without the water flowing
