The Wurkkos TS11 in orange has one big problem: The inside of the head is orange as well. This causes an orange spill, as you can see in this image:
Today I noticed that the bezel isn’t glued. So I quickly disassembled it, cut a piece of aluminum tape into the right shape and covered the inside of the head with it.
There’s still some orange from the outside of the bezel, but that can be fixed with a black marker or a 3D printed insert.
Nice job! I used GITD tape to do this on my green D4K, white tape with blue glow, and it brought Duv down .0010. I’ll have to snag some aluminum tape for some other lights!
