watchmaker,
Have you tried or tested the
Inova XO3?
I have one of them I keep as my nightstand light and one nice feature is that the tailcap can be set so that you don't even need to press the button. Just some slight lateral pressure on the tail cap will cause it to light. It is nice for those of us with arthritic joints. It works great in my the house for when go bump in the night and my dear wife makes me go check
I also have two of the X1's. My wife keeps one in her purse. I keep one in my concealed carry vest.
