Microstream "BLACK OUT" EDC Pen
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)
, 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:
(Left) Complete LED drive module as pulled from light. (Right) Disassembled LED module. Contact board on right was modified and re-used.
Module assy. showing bored out aluminum back half, and turned down copper front piece.
Battery contact board w/mods. for connection to aluminum module and added solder blob for battery contact.
Complete Module assembly.
(Left) Modified 12mm copper module. (Right) 2 styles of module retaining clips that I tried. I ended up using the simple home made spring clip on the left.
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.
A few indoor beam shots with some light fog.

A pattern made on the wall when the laser was shined through a wavy glass table top.
Or, .....this could be your laser on drugs!
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?
