Stealth cap performance
I put one of these on one of my previous model Betty's. I also have 3 of the new 5000 lumen Betty's. I did a side by side comparison, and I was amazed to see that the extra light transmission allowed by this stealth cap brought my old 4500 lumen head to just about equal to my new 5000 lumen head. I combined this with the new lens- which really cleaned up the beam pattern nicely. Lupine is an amazing company. Kudos.
