A couple things to think about-
First off, understand that "lumen" is a word that is subject to interpretation. There is not standardized method of measurement, so understand that there is no universal constant involved in lumen ratings for lights. My agency issues eXtreme Beam M1000 lights, that are 850lumens. I don't carry it, as I use my SureFire R1 Lawman, which is 750lumens. My SF R1 is brighter than the M1000. Part of that is due to the fact that the light produced by my SF is whiter, while the eXtreme Beam is bluish, which has a shorter wavelength. Quality companies like SureFire and Streamlight are pretty consistent with the way they measure their light output. However, other companies basically do whatever they want, and some just make up a number based on what their parts supplier tells them.
In my agency, we have FourSevens, Fenix, Streamlight and SureFire backup lights in use by officers. The SureFire lights are hands-down the best in terms of light output and quality of the light, as well as overall build construction. Streamlight is a close second. Elzetta lights are on par with that top tier. The Fenix, FourSevens and eXtreme Beam are all a lot lower quality. They work, and they're a lot better than the generic cheapies made in China, but they're not on the same level as companies like SureFire. Just because multiple people use a CREE emitter doesn't mean that the lights are the same quality or have the same output.
I push SureFire hard because they're hands-down the best in the industry. There is a premium for them, but for $100-$150, you can get a great cross-section of lights that are bombproof and have great light quality. Keep in mind that the quality of the light output is important, and it's not always about lumens/output levels. Many LEDs tend to get blue in color as they get brighter, and this actually has an adverse effect on your perception of the light quality. Top tier companies are able to keep their high output lights on the white side of the color spectrum.
Also keep in mind that LED does not penetrate well through debris, smoke, fog or precipitation in the air. Incandescent lights do that very well, but LEDs do not. This is why many SOCOM personnel and US LE SWAT personnel mount two lights on their rifles. One is usually an Incan, and one is a high-output LED.
A less expensive alternative are the Streamlights. They are about half the price of a SureFire, but still very good quality.
Now I'm going to punch a sacred cow... The other thing to note is that there is no universal "max output" level for any given situation. The concept that you can't have more than say, 200-250 lumens for indoors work is just the newest iteration of the old comments 5 years ago when people said you can't have more than 100-130 indoors. And before that, it was 60-90lumens if I remember correctly. The reality is that the max amount of light is how much ever you want and need. I run a 500 lumen SureFire X300 Ultra on my Glock 22 duty pistol and a SureFire R1 Lawman 750 lumen light for a handheld. Not too long ago, I had to go "tunnel rat" into a crawlspace of a house that was lined with sheetrock and drag out a fugitive who was hiding. Very tight, confined space and light colored walls. I used my SureFire X300 Ultra with DG Switch for lighting, because if the fought with me, I was just going to shoot him. I had no blindness issues whatsoever. He was blinded, and he flinched and quickly turned away when I lit him up in the corner of the crawlspace. While that light destroyed any night vision I adaptation I might have had, I certainly wasn't blinded. The suspect had to fight THROUGH the light, and couldn't.
I've done vehicle searches and searches of small residential rooms using my R1 Lawman when having my gun out wasn't necessary or appropriate, and it's not a blinding problem at all. White eggshell painted walls, not problem. When people say that the light will blind you, 9/10 times it's because someone points the light directly at a wall at a perpendicular angle, and then stares directly at the hotspot of the beam. Consider a flashlight like the sun, and don't stare directly at it and you'll be okay.
There is a reason why CAG, SF, SEALs, MARSOC, and several others are running SureFire P2X Fury 500lumen lights indoors, as well as outside (other very high-output lights as well). SureFire is actually in the process of upping the light output levels of their Scout line of lights due to demand for more light for CQB and open terrain cross-over.
Food for thought when you do your research. If you don't like super-bright, there's nothing wrong with that. If you do like super-bright, go nuts.
