Hold from moon cycles LMH
update, I tried DeDoming the 519a, and it did not work well w the stock Tir, it made rings in the beam:
However, I just tried a 20mm pebbled Tir for XP LED, and it works perfectly!
I dont have a photo w the 519a, cause I decided to swap in a 660nm Red… so here is that pic:
It is a 45 degree Tir, cause thats what I had handy,
usually I prefer the 30 degree… but in this case it does not matter, for how I use the light. I put it against my skin to help sore muscle recovery. It also stops headache, and works for Red Light Therapy for my old Retinas.
