The first flashlight I found was the SureFire CombatLight High-Intensity Incandescent Flashlight if only because I saw the price. This flashlight costs $270 where I saw it and it looks like a light saber(maybe thats taking it too far...). This flashlight is rechargeable and takes 3 rechargeable lithium ion batteries which are included, but you can find replacements. This flashlight also looks insanely durable. The description told me it is made out of aerospace-grade aluminum which has been Mil-Spec Type III Hard anodized and has a black/olive color. I have no idea what that means but it sounds good! I'm sure thats the reaction they were hoping to get. In all honesty this is probably just a fancy way of saying it has a normal anodized finish and there is nothing wrong with that. A finish like this holds up great, none of the things I own with this kind of finish have ever began to corrode. It also doesn't come off like paint so it always looks nice as well. It also has a Pyrex window which has been tempered to prevent it from breaking. It has been sealed with a high quality O ring and has a waterproof body. I don't think I have ever seen a flashlight that has followed such an attention to detail when it comes to durability
Now, for the high intensity action you were looking for. This flashlight has two options, it can either output 125 or 225 lumens. That is absolutely insane. At 225 lumens it definitely shows on the battery life. It can apparently only last 20 minutes on this setting as compared to 1 hour on the 125 lumen setting. Luckily the batteries have a 10 year shelf life so you can rechargeable them over and over again. The flashlight includes cables to recharge the batteries, a lanyard for easy carrying, and a lifetime warranty.
If you are looking for something a lot cheaper you can go with a flashlight that uses LEDs. High intensity LED flashlights generally just use a really large number of LEDs. I have seen ones that use anywhere from 20-50. While I haven't used it, I found a flashlight for only $10 that look promising. The trademark 75-5532. This flashlight has an incredible 32 LEDs which they managed to cram into a pretty small housing. The flashlight is only five inches long so you can probably carry it around in your pocket. It requires 3 AAA batteries so you won't be able to recharge the flashlight but thats the price you pay for getting a cheap light.
