Microstream "BLACK OUT" EDC Pen



O0bCfFK.jpg



Here's a little guy that's been forever coming together, It's a 3/4 length mini pen made by Streamlight, it's their "Microstream" model which I believe is their smallest offering.
So finally after two diodes, the first was just a very weak (83mW) w/G-2 lens, and two drivers (operator error):mad:, and a lot of just plain collecting dust, it's finally complete. :yh:

These little Microstream builds have been done a couple of times previously, namely by ShotGunDrums, and CynicalBrad.
My Microstream was on order back when SGD posted his build back in august; this will give you an idea on how long it's taken me to finish this up!

These Streamlight penlights make a great host for pen sized laser builds, they're a high quality host with a decent quality momentary/constant on tail switch.
The only thing that I don't like about them is the fact that the front does not disassemble; you have to pull the original led/driver assy. out from the front, and your new diode/driver module goes back in the same way.
Many pen sized lights are built this way, but a 3 piece host constructiom would be easier to work with.


Components Used For This Build:

  • "Streamlight Microstream" Penlight - for host & battery contact board.
  • Osram PLT5 450B 450nm Single Mode Diode. (DTR)
  • 12mm Copper Module w/Alum. back half. (DTR)
  • 'S Mini' Boost Driver set at 273mA. (Lazeerer)


Dimensions & Weight:

  • Length = 96mm (3.77")
  • Diameter = 15mm (0.59")
  • Weight w/Battery = 38g (1.34oz)


Measured Power Output:

  • 3 Element = 233mW
  • Acrylic = 258mW
  • G-2 = 323mW


A few photos! :wave:

Finished EDC pen with focus knob assortment. I ended up using the standard fluted one which I sandblasted and painted a flat black to match the look of the Streamlight.
The others are the standard chrome plated, a 'Survival Laser' black anodized aluminum knob, and a custom one that I made which looked real nice, but I decided on the all black look. :yh:

Here's a look at it with the custom adapter ....not too shabby!

Here's a couple of pics showing how small this pen is.

Or, .....this could be your laser on drugs! :D

That's all for now folks. :wave:

PS - I would recommend this penlight to use for a host for a low to mid powered laser. Being shorter than a "traditional" pen it clips in any pocket with ease, a truly EDC (every day carry) design! :beer:


EDIT: If anyones device is showing my photos as really large or all different sizes, please let me know, as I have two devices (phone and tablet) that show these pics as being fine, but my laptop shows some of them as extra large and others as correct?

Jeff, it sure has been a long time coming. I’ve been wondering when you’d get to this one. Nice clean work man!! I like how you modded the module and backshell. Very nice and excellent diode choice.
Thx too for the shout!!

SGD :beer:

PS here’s a knurled FA Rich gave me included with my first HS purchase from him. What an really nice guy he is.

Edit: +Rep
Forgot that part :D

Another great build and great documentation showing it. In the one pic showing your cars in the garage, is that a 1960 something (64-65?) Nova on the left?

Thanks AD, Bob, thanhtung, I appreciate your comments! :beer:

@Bob and AD, have to watch those guys! :eg:

@SGD, I know you've been wondering when I'd finally get around to this. You just reminded me to add links to yours and CynicalBrads mentions, so I just did, now people can access them without a search.
As it turned out, I really didn't need to mod the back half, because I ended up using a short S-mini driver in place of the originally planned and longer nano which I damaged.

That brass focus adapter is beautiful, looks real good on that pen!

Thank you, Bruce. :yh:
Good eyes, you're real close, it's a 1967 NovaSS.

@Encaap and Gazen, really appreciate the kind words, I like this host also, it's something a little different that you don't see everyday.

Very nice build as usual. The sandblasted focusing ring and custom adapter are a very nice touch.

That's tight. Yes the dark adjuster really tops it off nicely. :gj:
