Think I'm going to run mine at 300mA. Won't go higher than that because I dislike killing diodes and we don't have any long term longetivity data on these yet. Will have to see if my phone will do me a favor and take a few good pictures comparing it to 473 when I get done.

I don't know if you'll be able to see much of a difference between these and a 473 DPSS laser. Most are only 4nm apart. But, next to a 445nm it is dramatic.

Back when I had the 476/480, I remember the difference in color more dramatic than I expected. You may be surprised if you're comparing these directly to 473nm. Even 476 to 480 was as noticeable a difference as seen below: (right pair of spots)

And an attempt to compare them...

I'd describe 473 as a powder blue, and 476/480 as a crystal blue.

IDK, Zach. Your photos don't really capture the color. The top photo looks the same and the lower color comparison has too much green in it.

Sadly it's the last one I have of the 476/480 since imageshack removed all of my photos without telling me... Though the color around the spots are fairly accurate from at least what I remember. For a 4nm difference, I think that seeing an obvious difference is pretty significant.

Though, you've just seen the colors last week so you're also familiar with them. I made the bottom photo when comparing my 472 to 488. I did the comparison with my projector TV, which I believe is on its way out so maybe the colors are a little off. When I get up to my apartment tomorrow I'll check it out on my calibrated monitor.

Edit: for those who have seen it, it's about as different as 589 is from 593.5nm

Hi GSS,
I have noticed on a few builds i did the 12mm modules from Jordan were not consistent , in diameter or the seating of the diode. i press them with enough pressure no gorilla tactics . Some seat well and some don't ,The earlier modules i had no issues with but these some how were different. I use a small vice to press them in and i give them a good crank . If you look closer you will see the marks from the diode press being that i administered enough force . As for the focus knob i put a twist on it . glad you like it buddy.
I can see if it were a 44 that was harvested with some remnants of solder ,but these diodes are brand new not to seat correctly .

I noticed this same problem with my latest 5.6mm modules from DTR. I never had that problem in the past with these modules and with paying $5.00 each for them plus shipping, I want to know that I'm not going to have this trouble in the future. I guess I'll have to PM him about this. :undecided:

Hi Paul,
You made my sanity most clear now what i do is i put them in a chuck and fine sand them smooth instead of widening the 12mm makes no sense to me when 12mm is 12mm no matter how you bake it. So i just fit them easy button, you can put them in a hand drill with the aluminum backing on and just hold the sand paper while you operate the drill, Works very well and they will be hand fitted to your tolerance .
Thats the remedy for just the 12mm hole in the sink as far as pressing a diode in yes sometimes they don't seat all the way unless you use the GI Joe with the Kung Fu grip approach and that crushes the back of the diode and leaves an indentation.

My problem has been the diodes don't seat properly all the way into the "5.6mm" space provided for them. If I were to try to make the opening larger, I would risk making it too large and the diode wouldn't stay in place. I need some new copper modules, but want to know that at $5.00 each plus shipping that they will be machined better than my last batch. I don't mind paying 2 1/2 times the cost of nickel plated brass ones as long as they work.

Hi Paul,
The other remedy i came up with is ti by making my own copper back halves i can make them a little deeper in the thread area. By doing that i can insulate the back of the diode with arctic alumina compound it works great.

I understand you are doing what you can with what you have now. If I had more of these ill fitting copper modules, I'd be contacting Jordan to see if he could make good on them. I need to order more in the near future. I'll have to know that they will seat the diodes correctly before I shell out $27.50 for five copper modules.

hi Paul,
i understand and glad I'm not the only one with the same issue. maybe i will sand the inside a bit a test one out on a PLTB450B i have for a new build.

Yep same here I just had to press out a 473 from its 12mm module and press back into a 20mm module and I use my lathe vice it's small and perfect for this and it still didn't seat perfectly it's a half a millimetre higher on one side it's not noticeable but I'm sure it will be when it's in the host and the beam point to the side a bit, I have even customised my press modules from flaminpyro so that the press covers the whole back of the diode to stop them pressing in sideways but still doesn't work every time, maybe I shouldn't use grease!

Oh nice builds Lifetime awesome let me know if you have any issues using the xboost as I've had a premature death using one set to 300ma on the 473��

Hi BBB,
Did you try repressing the diode by rotating it it might fit flush. That happened to me once and thats what i did and it seated fine after i moved it around. As for the X Boost no problems with them ever set mine just under 300mA to 278 mA seems to be ok looking good so far buddy ..

If In fact it is on a slight angle my diode press press out tool had no clearance on the can and I'll probably damage the can, this only happens very rarely and only on the 20mm modules for me!

I can't believe I didn't see this thread earlier, Rich!
Those are a couple of nice looking gems you've got there; I don't know if they're twins or not, but they are a very nice 'pair'. :D
Your radially drilled "holey" focus adapter sets that build off beautifully, especially when turned on!
:gj:

PS - I've also had more issues lately with the 12mm copper modules; a little hand sanding will usually
take care of it. It seems that the front half and back half aren't quite machined concentrically with each other.
