Default NUBM44/Mag Light Mod

Hi Folks,

This is a Mag Light that i Modified The color is a Gun Metal finish With a huge Ed Crouse heat sink, much larger than Jayrobs sinks for the Mag light. OK in it is ;

1- NUBM44 diode = Jordan (DTR)
1-4.5A SXD Driver = Angelos (Lazeerer)
Lens G2= (AixiZ)
2-Fielong 32650/6000mAh cells.
It also has an insert to use 2-26650's cells.
Well hope you folks enjoy the build as much as i did building it. The worst part of building is when it's done, i just love to build these huge units.
Here are some pics to go with the build..

Very nice.

I am thinking about the 4 x C cell Maglite because 3 x 26650's and a spacer with a copper button/spring would supply power for 2 nubm44's both corrected and cubed via bounce mirror and wave plate, I was going to junk the head and make a 2.5 inch bar stock chamber.

I love the raw power of the NUBM44, and depending on what's going to happen in the future they may not be around forever, everything may go Gball, or worse.

Everyone who loves raw power should get a nubm44 and quality safety glasses while they are available.

Hi Red,
Thanks for looking I'm thinking of getting 2 more diode just to have. I have an NUB41 diode in stock had foursome time that should do 7+ at 4.5A . i'm going to try 5A with the next 44 i get. Want hat 7+w's. Even in the mag light sink it gets really warm fast thats how powerful these diodes really are and thats a huge sink to start. Going to get a few CU sink made and so they protrude out from the front of the build to give it more mass.
I would sure like to see you c cell build now that's epic wow!!

It's a powerhouse diode, we just have to get that power into a small area where we want it and then the magic happens, alla ca poof

p.s. Yes the diodes do make a lot of by product heat, but the newer diodes are more efficient percentage wise, but more power means more heat.
I have a head with 3 x NDB7875's in it all at 2.4 amps each, it's 2.5 by 2.0 inches round aluminum and it gets hot in a couple minutes, a lot hotter than I expected.



I like your idea of using more copper, that and more surface area, fins work well, it's just a matter of making them look good on a build, more copper will probably be a big help.
Multiple beams look so awesome at night.
--------------------
p.s. I didn't mean to hijack your thread, I just though as we were talking about heat that you would want to see what I was talking about with3 x 7875's.....wow just imagine 3 x 41's that would be bright, lightning bright.

Uber cool, nice work. In the past I've always thought a heat sink without fins was like a root beer float without the ice cream, but when you have a piece of metal that massive as the heat SINK.... it can sink a whole lot of heat for a long time and isn't an issue for the duty cycles we use. Nice looking, love that cool looking add on for the output.

Hi Red,
No hijacking here brother that's why were on the forum to exchanges points of view. Wow i seen your post on the 3- diodes thats a lot of power in one spot. Want to put a 41 in something real special. Nice lathe work to . Thanks for looking and your replies welcome always.CU is the way to go with these diodes..

Rich

@ Alaskan ,
Thank you for the kind words appreciated yes mass is the key word with these diodes. They do generate tons of heat. As i said CU is the way to go I wonder if Harold can do this for me ?? I tried contacting Sulman in the UAE but no reply for about a moth now about some work i need done.
I have 2- of Jay Rob's sinks there great mass to. Wish he did them in CU again he used to a while back.
Thank You Alaskan very much Pal..

Hi Red that focus adapter is from Ed Crouse he was bad a$$ forgive me but he was awesome and he anodized his pieces to colors you needed fit for the job. I miss that guy he did some cool stuff for me. Don't get me wrong all the vendors here at LPF are non replaceable we need them. Glad you like it enjoy ..

Lifetime my favorite pic is #4 that little module just smothered by that big bad boy sink, it looked lonely in there but it made it up in spunk by all the heat that I still cant believe something so small can make
All ad ons are welcome in my book RedCoboy kudos to you also. I'm going to have to start lifting weights again if I were to get one of those beautys with a larger heatsink.

Hi Gss,
Thank you brother for looking and the kind words. Yes it is looking a little lonely surrounded by that AL sink. Heat is a big issue here with these diodes need lots of cooling. I think these diodes would do better in a cooled Labby custom build. And yes that Cowboy build is really sick i love it.
Thanks Buddy

Hi,
Update on the power out put on this build , i rebuilt the unit taking the driver off the heat sink and Epoxied it inside the battery tube in front of the switch. Also reset the driver from 4.5A to 4.850A huge difference in performance. Well here's a chart to show the reading. here it shoes 7W's but the the W's kept climbing to over 7200+W's

Hi GSS,
I have no idea but this diode kept climbing past 7200+W's no problem,and the heat was absorbed by the mass of this sink like a champ temp was a little warm overall now that's heat sinking doing it's job well. Mag Light builds for these high power diodes are the key. With a full CU back on the module and Arctic Alumina can't go wrong it terms of heat transfer Thanks for your reply aways welcome buddy...

Just got back to this. But wow, a portable laser with 7.2W at that stability is amazing. I'm considering building one myself to keep. Maglite has some seriously tough hosts, with that huge space for heatsinks.

Hi J,
Thanks yes the mag light hosts offer the largest mass for heat sinking for the power house NUMB44 diode. With a full CU baking on the module and all that AL works flawlessly. You will really need to use 2-32650 cells in it but 26650's are fine but drop a lot faster.

Default Re: NUBM44/Mag Light Mod

Nice, can't REP again yet.
I have a couple mags and a couple other large size hosts that have been around awhile and I just can't bring myself to put anything in them just because of the size. Built a whole bunch of units recently including a bunch of under 500mW single modes in laser66 pens.
In case Alaskan visits back here I want him to know he inspired me to do the single modes and I'm glad I did. So far I have built the following (not including a bunch of bdr) bought through Jordan:
Mits 180mW 638nm, Nichia NDG4216 515nm and the Osram PL450B. I did deliberately pick the more powerful single modes. Don't know if I should bother with any of the other less powerful ones at this point unless someone can give me a good reason other than I haven't used them yet (such as the divergence is way better in the Opnext/Oclaro 120mW 638nm compared to the Mits 180mW).
Sorry if I went too off topic but I think Life keeps things loose in his threads like I do.
Red, I don't know if I can really say I love that focus adapter as far as looks but I absolutely love that it lights up like that. I think it's the tip that bugs me but please don't take offense, it's just not me is all. Think I'm just a bit more conservative than some of you guys although that sounds weird considering how many units I've built into different hosts. I do have one unit that lights up a bit like that and it's one of my faves. Would like to see more focus adapters in a smaller size that had the side holes in them.

Default Re: NUBM44/Mag Light Mod

Hi P,
Hey nothing is off topic basically, different views brought up are always welcome. And i like your honesty on the topic. Ok those 660nm diodes they were 5 for 18.oo bucks that you mentioned i purchased 5, good pen diodes. And i also have coming 2-450 single modes and 2-520 singles.

Well as far as focus adapters go in your favor here's one of Jeffs hydra's and i drilled the holes it it to emit the beam. I put it on a brass 66 pen / Mitsu 500 just for an example.
Also here's another Mag Light build i did with a huge sink custom Made by Ed Crouse he was good , miss him. So here's a few pics for ya buddy..
