1. you WILL need a fan

I have a fan for it so yes.

2) I’ve tested some of those drivers… forget doing 100W.

as long as it lights up pretty bright, I dont care what it does…

kinda contradict the title of this post

Just got the special meter, and it does sorta prove the point… peaking at 60 watts right now, but due to the 12volt 4.5ah gell cell battery I’m using for testing, so I need a better battery, looking at a lifepo4 12 7-9ah battery. may go up a cell, but I’d need a different fan. might switch to 24 volt battery setup instead, dont know yet.

I hope to have a nice 100 watt flashlight soon, using some stuff from ebay, housed in a 105mm brass howitzer shell.

will post some pictures later, esp once I get the brass shell.

I loved the 105 howitzer, it was a blast to shoot.

know where I can get a empty brass shell from one cheaply?
cheapest I’ve found so far is $75 from france

You just reminded me that I own one, I had forgotten all about it.

I don’t want to sell mine, but looking at it now, I can see that it could use a good cleanup.

Find a live shell and whack the bottom with a hammer… it will empty itself. J) Oh, and we want video of the process… :party:

that would be even harder to find and I think you would need nail too

thanks brad, I will check it out… maybe I can find something suitable

[firehopper]

got a minghe bst400 400 watt digital boost CC thingy, I’ll take pictures soon, this is if the 100 watt converter doesnt meet my needs… might make my own 4 cell lifepo4 pack with a BMS for it. it might be cheaper but it will be more along the size I need for this light.

I am mighty curious to see how this turns out. Looks pretty awesome so far.

[Andyman]

In to watch. Looks like a fun project!

[firehopper]

next update, have the 105 howitzer shell ordered, sent money, will have to wait for him to get the money order then send it. so yeah a bit of progress, no new photos yet.

[onetrickpony]

Cool idea, good luck with the rest of the build

[firehopper]

thanks, hopefully it goes well.

[firehopper]
