All gear has it limits and it’s tolerances and not everyone will push gear to the limits, but in this industry, we have so many different lines of work that report back to us that it’s always part of our job to listen so we can relay that to our customers, as long as it passes our bull shit meter.   You get what you pay for and Surefire Flashlights are not in the “cheap” or “inexpensive” category although their history in the Military is well known and complaints about the cost are the only thing we hear that are negatives.  You have to read the product specs and what a flashlight is designed to do to understand what you are paying for when you are shopping for an LED Flashlight for your M4 Carbine, M16 or Remington 870 or Mossberg 590 Series shotguns.   Having a hi and a low power setting means longer life of batteries and be careful you don’t just buy a light based on the lumens.   A 320 Lumen flashlight is going to burn faster than one that can be set to 15 Lumens and only use what you need to use.

Flashlights, just like lasers are often not used properly and I would also highly recommend getting a red or blue flip up lense at the end of any weapon mounted light because there are more times than none, going to be situations were you don’t want high output because shining a 200 Lumen to 600 Lumen light in low light or darkness is like turning the sun on and it is true that you may more likely draw attention to you which can give a burglar, home invader or prowler or felon a return firing point.   The Surefire Flashlights like the Scout Model went from 110 Lumens to 200 lumens and considering how small and lightweight it is,  I’d highly recommend that you pay attention to the pros and cons of using pressure switches because they do break and it’s also recommended that you keep spare ones close to  you incase of failure.   We’ve seen a big up tick in the sales of the Surefire X300 Ultra due to the fact that this is easy to put on a handgun or a rifle and doesn’t require a pressure switch to activate.
