I was doing laundry last night and look what I found in the bottom of the washing machine.
I had left my Streamlight Microstream in the pocket of a pair of jeans and it went through a full wash and spin cycle. The Microstream is a great little light. It delivers 35 lumens with a 2.5 hour run time on one AAA battery. After muttering an expletive or two, I unscrewed the light to see if water had gotten past the O-Ring. The inside of the light was bone dry. After crossing my fingers, I did a function check. Low and behold, it lit up like a champ. The Microstream is one tough little light.
