Not sure where I first saw the stainless sea sick (c6) hosts, but I love the look of them, and have been wanting to build in one ever since. So a few months ago, I ordered a pair of them, figuring I would get around to using them eventually. The other item on my want-to-do list was building a 1W direct green handheld. I think a big factor in waiting so long to build one was diode prices. I would loved to have used one of the NDG7475 diodes, but for the same reason, went with a De-canned NUGM03 instead. I've experimented with a few different lenses so far, but so far prefer the beam produced by a 3E glass lens. I still just cant get over the brilliance of this color at this power level. Even next to a more powerful 445nm blue (3rd pic), the visibility is stunning.
I love the challenge of building in tiny hosts such as penlights and single cell compact flashlights. The wow factor of the finished product is amplified that much more when it's effectively contained in such a small package. That said, this one REALLY tested my patience. The most challenging part of this build for me was battery fitment. This host originally used a single 18650, but the buck driver pushing this diode requires twin cells. Ended up using a pair of button top 16340s as they were the closest thing I had to half the length of a 19650. A few millimeters make a huge difference so I ended up having to modify the negative contact, spring, and back half of the heatsink to make enough room. Still need roughly 2mm more clearance to get the host sections to sit completely flush. Pretty sure that problem will be solved by switching to flat-top cells instead of these protected ones, but we shall see.

what current are you running it at?
