Great work and very generous Larry. I'm fairly new around here, but this must be one of the greatest colaborations on a light.
All you guys exemplify the best of CPF; the selfless pursuit of the best flashlights have to offer and a willingness to share your enthusiasm, knowledge, and creations with others all over the world.
I'm really torn between the need for Larry's safety and the desire to keep the "S" in USL. I think the integrated metal safety looks cool and actually adds to the overall appearence of the light, both form and function you could say. Larry's design says that there is more than meets the eye here, something potentially dangerous, something serious deserving of respect and caution.
My best thought on the safety issue in terms of a removable safety is to take a rubber eye cup to the dentist with my USL. Lay a velcro strap across the cup and ask the dentist to fill it with that stuff they use to take a mold of your teeth, and mold it to the switch in the off position. Strapped in place, this should secure the light.
So...what to do? What do you guys think of the "dental cap"? How much time do we have to decide? Larry's safety is certiainly the more elegant solution that gives the whole light a certain edge. I think I'm leaning that direction, especially since it looks like it has become an integrated part of this whole project. While I want an ultimate STEALTH light, I also want the light as you guys envision it should be. This is your baby and I am grateful that you have included me in this whole project.
