4.5W 465nm NUBM07E Build

Greetings, my fellow LPF-lings! Today, I share with you my latest build. An NUBM07E in an MX900 host. I know I've been using MX900s a lot lately, but I do love the host and Rick's full copper modules for it. I've got one of Moh's aluminum heatsinks as well, so I'll be building one of those soon as well.

The Parts:

• NUBM07E diode from our great friend DTR
• SXD Driver by Lazeerer, also purchased from DTR
• MX900(XM-L T6) host from BudgetBeams.com
• Full copper module/heatsink from Rick Trent
• 3-Element Lens, also from DTR

So I purchased two of these from DTR, and this is the first build. I decided to run this one conservatively somewhere around 3.9 amps because of Alaskan's diode failure at 4.5 amps. His might not have been due entirely to current, but I would rather play this first one safe. I got more than enough power out of this one anyways, as I maxed out my 3.7W meter, even after putting a 3-element lens on it.

This thing is a beauty. I just love the sky blue beam. I can't wait to build the second diode. And order some more.

Now for the build!

Here's the new diode, with its shiny "G-Ball" lens. This one came out alright, but the other cracked while removing the can. I plan on seeing if I can remove the lens and make use of it somehow.

A macro shot of the diode after removing the can, and another of what it looks like in its new home. Looks comfy to me! But slightly cold. Better give him some heat!

I soldered the leads on, heat shrinked them, and VERY CAREFULLY(open can) applied Arctic Silver to the sides and rear of the diode. A toothpick works nice to spread the paste when you need to be more precise than the Arctic Silver spreader will allow.

The almighty SXD, pumping out somewhere around 24,375,000,000,000,000,000 electrons per second.

The SXD sinked to the inside of the heatsink with Arctic Alumina, and some extra to ensure the driver doesn't short out on the contact board.. I've had great success so far doing it this way with both this driver and another SXD pushing an NUBM44 @ 4.5A. That's a 20mm battery contact board from BudgetBeams.com attached. And finally, a 3-element lens to complete the build. I used only PTFE tape(no spring) to eliminate slop while adjusting the lens and, more importantly, to keep particles/debris from getting near this expensive, naked diode. Lol.

The finished product, along with power output. The Ophir measurement was taken with a G2 lens. Peaks around 4.5 watts, and holds there pretty steadily. I decided to put the 3-element lens on to see if it dropped the output enough to get an accurate measurement. It didn't. 3.7+ watts with a 3-element lens.

And now, let's roll that beautiful beam footage:

Here's a random cool shot I stumbled across when I tried cutting a spring with this one. I was using the 3-element lens. It didn't cut the spring, but it burned it enough that it just fell apart when I lightly bumped it.

Thanks for looking! Enjoy! As always, if I can help anyone with anything, just PM me.

P.S. Let's see if anyone can figure out what is missing from several of these pictures.

Most pictures aren't showing up

They are for me. Could be that he's fixed it in the meantime though.

Very nice build! Do you plan on running your second diode at 4.5A like Alaskan did?

It works now. I guess he fixed it

I plan on putting it in my larger aluminum heatsink with fan and seeing how much more power I get and if there's a noticeable difference in wavelength.

As for the pictures, it was probably just issues with LPF or Photobucket because I didn't change anything.

I am interested in removing this lens and mounting it somehow to see how it compares to our other common lenses. If anyone has done so, feel free to chime in!

I just ordered 2 of those flashlights, 4 26650IMR's and a heatsink from budgetbeams, I was thinking about a copper heatsink for the 2nd but ricktrent doesn't have any raw ones on ebay at the moment. Does he have a store other than ebay?

No. I'll PM you.

Edit: Just talked to Rick, and he said it was alright to post it here. Email him at Ricktrent4@yahoo.com if you need anything of his.

I started looking at 26650 batteries for these, but then I realized that I've never had any batteries actually go dead on me. Lol.

About to build the second one. Struggling to decide what current I want to go with. Hmmmmmm....

Great Wavelength, great build. But somehow I do not like the host design.

Hi tatermay,

They can run comfortably at 5A. i built a Modded Mag Light build i modded myself. In the host is the new 465nm diode / 5A SXD with a long ramp up so the diode doesn't get smacked with a rush of current and a G2 lens using 22 gauge wire. Mine puts out 5500W's and a shifted WL of 470+WL. Here is some pics

Thanks. I love these hosts, and I definitely love the full copper heatsinks/modules. They've held all of my high power builds, up to 7 watts so far, like a champ. I like them so much more than Mag Lite hosts. Exception being Lifetimes, below. That focus adapter is awesome, and just makes it for me.

I've got about 6 or 7 different Ehgemus hosts that I will also be building starting this week. One of which is a ray gun host with both a sight laser module and a high power module that will be controlled by the trigger. I plan on building some sort of steampunk style beam expander for it. It will either be this diode or the 7 watt NUBM44.

That looks awesome. Did you build that focus adapter. I want. Bad. Lol. I'm too afraid to run mine at 5A right now, especially with Alaskan's dying very quickly at 4.5A. But that does look amazing. My camera even makes this one seem slightly violet in some pictures, but it is very much sky blue. I will definitely be building a bunch of these.

Congrats, must spread some REP around though
I'm very curious as to how the all copper setup sinks in comparison to the aluminum one from Moh. I used one for a 2.8W blue build already and bought a spare. Haven't seen a pic of the side of DTR's copper module but I'm assuming it touches the back side of the diode. Is that correct? If that's true then I would think it would sink better than the aluminum one unless there's not a tight fit to the copper sink. What do you think or have you tested this yet? Of course I'm sure the copper sink isn't cheap.

Just got some of my questions answered by watching Ricks video. Looks like he has a lot of them for sale right now too.

*see the new 1W 520nm listed on Jordan's site Don't see specs yet. Can't click on his link yet so think I caught him setting it up.

Nice build! :beer:

What about divergence?

Will measure this weekend. Haven't done so yet. It is definitely worse than the NDB7875, but possibly slightly better than the 7A75? Purely estimates though.

Thanks for the pictures and build info.

Nice job!

Great macro shots too...
