I saw your previous thread asking suggestions for long guns. If you plan on mounting it, I would personally recommend a Surefire model specifically built for repeated recoil.
Other than that, there are countless options and brands from many manufacturers. You might peruse some flashlight forums and/or figure out what options you want. I personally have had good experiences with everything from a cheap Brinks model to more expensive Surefire, and other brands in between that price spectrum.
I currently use a Fenix rechargeable for my bed stand, Nitecore rechargeable for my briefcase, Eagletac for my EDC, and an old Surefire for when I travel or ride at night. Nowadays, there are even decent, bright LED flashlights at HD.
I'll also add: 1. after having to work on an old house at night with no electricity, a good headlamp was invaluable. 2. Although throw and brightness are great for certain tasks, I often use a flashlight with more spread and less lumens for dark indoor or small area illumination. My friend is the opposite, as he needs to illuminate dark crevices on the under belly of vehicles in a bright shop. Therefore, you might want to tailor your search to prioritize situations that you more commonly find yourself in.
