I remember upgrading from the XENON bulbs to LED Upgrades on several of my flashlights a few years ago.   I was using Streamlight Scorpions and Surefire G2 flashlights that I believe were around 80 lumens each and I was impressed back then at how bright they were.   The only piss off I had with them was how the bulbs didn’t really last that long and I didn’t really like the lack of reliability, regardless of how bright they were.   The Streamlight Scorpions were upgraded to about 130 Lumens with the Upgrade kit, and the first thing I did was mount them on my AR15 rifle.   I was very happy having a weapon mounted light on my guns when I was up in the woods of Pennsylvania but I also choose to put a flip on red lense because I learned in Boy Scounts that bright lights can ruin your vision at night.

The old Army Flashlights had multiple lense on them for variations on lense width always came with a red or blue lense.   I don’t know why people forget this when they buy high lumen Streamlight Flashlights and thing 300 Lumens of light is going to win a fight when having low light abilities and being fast on your feet is a much better strategy.    Streamlight is a very good company to choose from and their price points and warranties are going to make our customers feel like they spent their money wisely.   Remember that the light you have on your firearm is not the light that you should always use for searching for something.  Having two flashlights on  your person is really the way to go.
