Done deal. Mony sent.

Your green is on the way Mark. It tested pretty much identically to the first time I measured it.
And on the sipik build I did for myself with a NJG-18, I filled up the cavity with silicon heatsink compound. (not thermal grease, but thermally conductive silicon that hardens)
@ Mark- > great job at your build and I like your video. It was presented very well, especially safety glasses wise. :gj: +1.
@ Qume- > great idea witht the thermal silicone. I only get 40 sec before my AL gets really hot, but I have been brainstorming driver heatsinking ideas. The only downfall I see with the silicone is disassembly/repair.
What current are you running your build at in the AL host Rocket? I'm not sure what mA mine is set to. I just made sure the driver was set low then did the build and sealed it up.. since the pot is external I just ran it off the power supply set at 4.22v then turned up the pot until the output was what I wanted. Namely just a hair over 1.2W. The heatsink got hot fairly quick by itself, but with it screwed into the host the extra surface area helps a lot apparently because It doesn't get as hot as it did just as a bare heatsink.
Well, if these drivers are discontinued it's moot anyway. I have a few left but i'll keep them for myself.. since I want to build myself a complete set of sipik's in various wavelengths for myself.
I still think i'll try to design a 17mm CC boost/buck myself though.. Won't be as cheap as the njg-18's but if it's my design and my construction.. at least I won't have to worry about them vanishing on me.
