I have done many small mods on flashlights, I mean this is my 3rd big one and my 3rd on the forum.
Exaclty, the refectors are epoxied together with smth like JB weld.
I made lots of templates from paper to see exaclty how much I needed to cut. At the end I just cut as much as needed to not have a hole in the center of the reflectors. Theoretically if you have a bigger head you can avoid cutting or you can cut only 2-3mm from each, you will end up with a hole in the center however…
Very cool light! My guess as to what is holding back the output, the cells. You stated they are 3400 mph panasonic, assuming they are 18650 “B” then they won’t flow the kind of current you need for more lumens.
After I found out with paper samples the best shape, I cut a metal template and used this for all 4 reflectors to make them all even.
I started cutting with a small saw, then squared them with a small disc sander that I have.
Skyrays are only one size of what I know, the big head is a camera lens hood and some aluminum discs.
The original body ends around 12mm from the switch. You can tell where the extra parts start from the glossy color, I didnt have matt black spray
Here is the template, I was cutting the part of the reflector that was outside of this shape!
Oh, so you used Al disks of alternating diameter to create the fins. It looks really clean.
As someone above mentioned, if you are using the NCR18650B cells, these will significantly limit your output as they have pretty high internal resistance.
You are right! I thought these batteries are capable for what I wanted, but I tried some 10amp LG cells and the lumens are indeed going up… Thanks for the advice!
I’m with ImA4Wheelr and others with their comments. This is a really nice mod. The reflectors look amazing and I admire your skills in building this wonderful light. Thanks for posting it up.
One thing, next time dont be shy in posting up lots more pictures in the fabrication process.
Long live Justin. :+1:
