Surefire Flashlights, Weapon Mounted Lights, X300U, or mount a G2X
There have been many improvements across the board with various flashlight companies. Ever since LED technology advanced, you are getting flashlights with the same SKU, UPC Code, and price that you got it for 4yrs ago but a much better light. I think there is a ceiling for many of these advancements. there is absolutely such a thing as too much light. The real thing to consider is if you are using a firearm indoors, or might be using it for outdoors. Recently I was attending a low light shoot. I watched the majority of people use flashlights in the 110-200 lumen range and at 50yds, it was good at lighting up a target. I took my LWRC M6A1 with me and tested out my Streamlight TLR-1 which is 300 lumens and even though it didn’t have the beam I would like to have, it really did an excellent job of lighting up a wide field in front of me so I could see just about everything I wanted it.
For indoors over 200 lumens can be an annoyance and somewhat of an inhibitor because you will get so much reflection off of shiny objects that it can actually ruin your vision in low light. You want the light to light up what you are pointing at, and not a whole bunch coming back at you. One thing I’ve known for a long time is have just enough light to see an object is better than lighting up everything, you have to give you eyes time to adapt to the lighting changes and given the majority of most people’s needs, 200 Lumens is a good. There are several Surefire Flashlights that are considered hand held lights but they actually make excellent weapon mounted lights, one of the main reason I say this is they have hi and low power settings, I don’t know why Surefire and Streamlight haven’t incorporated this into the X300U and TLR-1 lights but I think once you get to that 300-500 Lumen range, you might be better off with having the ability to drop down in power the majority of the time, and only use full power when needed, probable outdoors.
