I picked up a Viseri VZ230 a little while back, and I really like it (other than the fact it’s pretty much impossible to mod without destroying it).
Anyway, I’m not crazy about the lens. After using LED’s for a while now, I can’t stand ringing and the artifacts. I put some matte Scotch tape on the bottom side, and it really smoothed out the beam; unfortunately it also cut the light output dramatically. My next experiment was to lightly mist some clear packing tape with Testor’s Dullcote. Again, it made a nice beam and again, it cut the light output too much.
So…
1. Is there a replacement lense available that will smooth out the beam without seriously cutting light output?
2. Is there a good method for modifying the original lense to accomplish this?
