I know. 4 years…
Anybody know if these still exist anywhere? Randy hasn’t logged on here for nearly a year and his site is still down quoting a large contract order consuming resources. Very interested in a lens like this if anybody has any pointers I’d appreciate it!
I use simple diffuser cut out to the size from Gerber printer vinyl, normally used for labels and placards in aviation (withstands 135 deg. C and has some flame resistance).
Similar materials are used for backlit posters, bus stop advertisements etc.
Vinyl is 10 mils thick (0,25 mm), frosty on one side and clear and smooth on the other. It’s very hard to scratch and protects glass on the flashlight well as an extra bonus.
It’s probably quite ineffective and blocks some light, but I don’t mind, I like smooth beam and don’t care about some lost percent of light.

Added diffuser (sorry for the shadow):
Without diffuser:
And with installed one:
Some years ago I tried to find an alternative source…and failed at that.
I found this Beam-Mixing LED Diffusers | BrightView Technologies, Inc.
Not the same thing for sure, but interesting
Indeed, very interesting.
