I recently purchased a Streamlight Strion On Ebay used, the seller told me it was nearly new and had only been used a handful of times. The Flashlight was in prestine condition when I received it and I had been using it for 4 days now. It recently had shut off on me when I had powered it on, it would turn On for a second then shut off immediately. I tried pressing the button several times to get the strobe to work but it doesn't. I also noticed when I have the Strion On for over 5 minutes the flashlight would get extremely hot, I am not sure if this is normal.
