I'm sure this has been thought of, but I wanted to share. 2000 grit sand paper and a little work. I need to do a bit more sanding to get a true flood, but after about 5 minutes the beam is a lot like the v3 wildcat. I will keep working when I have time. I want a wall of light. I look at this as a way to customize the HD 18650 beam to how you want it without a huge expense. The extra lens cost a few bucks. Depending on the job at hand I can just swap the lens.
