Personally, I only see 3 names in the hand held flashlight industry. There are prob others but these three cover it for me.
SureFire
Fenix
Streamlight
In that order. SureFire is the standard, you can use their website to narrow down particular models to suit your needs. It's does pretty good narrowing down and comparing the different models. They have a new like too that looks really good. SureFire excels in durability and the fact they have momentary tailcap switches. The downside is most models are very pricey. I have owned several of their hand held models and one pistol mounted model. I personally now own two of the G2LEDs. These aren't putting out as much light as you asked for and don't have variable power or strobe. I still like them and they are relatively inexpensive by "tactical" standards. The batteries last a long time and I prefer the poly bodies to metal ones.
I have a Fenix light that I picked up recently that I really like. Fenix is really growing in market share as they are durable, inexpensive, and put out a lot of light, most at varialbe powers. Many have a strobe feature. The size is great for EDC ... even better than most SureFire models. The down side is most (maybe not any) have momentary on/off tailcap switches. That is a killer for me from a "tactical" standpoint. I carry the Fenix as a EDC for general use but if I go looking for bumps in the night I grab the SureFire from the nightstand. The Fenix website is OK but can be overwhelming until you figure out their "series" designations.
Streamlight ... a consistent player in the market as well. They are nothing to sneeze at and are much more reasonably priced than SureFires but admittedly I don't quite put them in the same level as far as durability. That's just from reading though as I only have 1 Streamlight and it's a tiny 15 lumen MicroStream I picked up at my local gun store. I love that little thing though and carry it even more frequently than the Fenix for general use as it is smaller and runs on a AAA battery, still LED though. It does have a momentary on/off switch. I just find for general use even a low power light such as this serves most any purpose I have. I just purchased a TLR-1s though for a nightstand pistol mounted light. I am anxious to try it out. I previously didn't give the TLR series much look given I liked the way the SureFires and Insight M3X attaches better. At $99 though ... given the output of the TLR-1s ... I couldn't pass this up.
