My Sunwayman 491nm Pen Build
Hey guys, here's another little pen size build that I've been working on forever; it's built around the always beautiful Sharp 488nm GH04850B2G (SB308B292) diode.
I was looking to find a wavelength to fit between my 488 and 493nm builds, so, on this project I set the output on the driver (X-WOSSEE) to only 175mA or so.
Finally after finishing it and having it sit around all summer, I found time to send it off to Paul (paul598419) who kindly spectro'd it for me.
Happily, it turned out to measure in at 491nm, just about perfect for me; Thank You Paul!
I wanted to keep this pen looking as close to original as possible, but still provide "some" extra heatsinking ability, so I turned a minimal aluminum heatsink that fit snuggly on the pen host and also on the 12mm copper module.
I also added some grooves and angles to match the style of the Sunwayman pen, and finished up with a matching matte black paint finish.
All in all, the Sunwayman provided a great basis for this project, it has nice quality threads, a handsome metal tailcap switch, and a nice accenting chrome pocket clip.
Components Used For This Build:
- Sunwayman P02A Pocket EDC Penlight.
- Sharp 488nm GH04850B2G Diode. (DTR)
- 12mm Copper Module w/Aluminum back. (DTR)
- "LDSE500" Driver, set at 175mA. (X-WOSSEE)
- Custom Aluminum Heatsink
- 2 x 10440 Li-Ion batteries, 350mAh. (Efest)
Dimensions & Weight:
- Length = 154mm (6.06").
- Diameter = 13.9mm (.547) Body/ 17mm (.667") Heatsink.
- 41g (1.44oz) w/o Batteries.
- 59g (2.08oz) w/2 x 10440 cells.
Measured Power Output:
- G-8 lens = 95mW average, 104mW peak.
- G-2 lens = 111mW average, 121mW peak.
I know that this is a lot of crap for a simple pen build, but it gives me something to do, and keeps me out of trouble.
Anyway ....here are probably too many pics, but I like pics, Enjoy!

Thanks for reading and watching - till next time!
