No matter what product you are thinking of buying, one thing that might influence your decision more than anything else is the brand of the product. However, it is important to note that this is not always going to be a good indicator of quality. Some brands inflate their prices for no reason, others use gimmicks to make their products seem a lot better than they actually are. At the end of the day, the thing that really matters is getting something useful, not something that has been made by a big name brand.
This is particularly true in the case of tactical flashlights. There are a few companies that have become big names in the industry in spite of the fact that it is still quite new, and reading reviews online would show you that these big name brands are really not as good as they are cracked up to be.
That being said, this does not mean that brand does not matter at all. While you can certainly get an excellent tactical flashlight from a low visibility brand and get a better experience than the bigger names might be able to provide, the same cannot be said for batteries. You should definitely go for big names here because this the only way to make sure that you would be able to use your flashlight for as long as possible.
Your flashlight does not work on its own. It needs a power source, and buying a top notch power source is essential to staying safe when your flashlight is your only source of lamination. Low brand visibility usually means that the battery said brand produces would be subpar, so you should avoid them at all costs.
