520nm HD 250mA Defiant (extended copper sink)

[jander6442]

Well I had finally put together a 520nm build using a diode from our local supplier
DTR... at this point of the game I did not even think of the efficiency of my diode, but I think I did good:bowdown:.

1. PL520 diode
2. MicroBoost driver set @250mA
3. 1 Home Depot Defiant host 19.00 US.
4. 3 element 445nm lens
5. Copper heatsink, module, driver sink.
6. 1 22500 bat.
7. Arctic silver paste and Arctic ceramic adhesive.

One thing to mention is copper sux to work with

Using copper means finger prints right:thinking:... no, you must clear coat it:beer:

Why jander, why the copper driver sink?... cause I can. Muhaaaaa:eg:.

I had to make my own contact board as I misplaced the original. I used an old LED board I had laying around and it fit perfect.

Finished product. Very clean and solid build, man this little thing is heavy for it's size.

I really like the diode overall, I plan on doing some more builds in the future using this sweet little greenie.:bowdown:

Now for the numbers. I set the little greenie a little hot, so I would call it a little above average I guess I could have drove it higher, yet I think it's fine for now.:beer::yh:

I want to thank those who took part in the murder test thread and other testing threads/info gathering, as always we as a whole make it better for the individuals in this fine hobby. Thanks for looking and get out there and build them folks:thanks::wave:

Great build all the way around. Great work.:beer:

 

[Blord]

Very clean build and indeed copper rocks !

 

[sinner]

Very beautiful work, as always :beer:

 

[Shakenawake]

wow. pretty sure 100mW from a diode driven at 250mA, and using not a g lens but a 3 element, means you have a superb diode

 

[Tmack]

^^ for sure. That is quite the reading at that amperage. Have seen them run at over 300ma to produce that much. Great diode for a very nice build

 

[cheech226]

wow, i dig the host, good find. fine build man, looks like a keeper there.

Nice build! I need to get myself a lathe, so i can make my own stuff Anyways, 100mW+ at that current is amazing! Very efficient diode you got there :beer:

Copper-sting dark green defiance must feel damn good. Decent close-to-pocket size, solid weight and strong performance make this specific build quite different if compared to other ones in the 520nm class!

:gj:!

 

[grainde]

Damn I wish I had a lathe...Great job, that little laser definitely lives up to its name! :beer: +1

 

[BowtieGuy]

Another very nice build! Great looking host/heatsink combo, and over 100mW too!
I agree, that clearcoat will keep that copper looking good for a long time.

 

[SerpantSlayer]

Very nice build! Is that clear coat you used good? Does it peel off easily?

 

[jander6442]

Thanks for the kind words. I really dig this diode I haven't put this build down yet. I only look to put some sweet bright green parachord around it then down with a lanyard.

 

[sgtbilkodle]

I DIG it. I suppose that was used in some of the killer beam shots ya posted...dang, inspiration to get me busy with the next project!

Kinda makes me want to buy a new controller board and get my lathe running again

Is that the harbor freight 7x10?
I went through a few hi/lo plastic gears before I bought metal replacements for it.
