Hello, I am new here and would like some help.
I have a severe vision impairment with terrible night vision. I want to get an extremely powerful flashlight for navigating at night.
I need a lot of light (I'm thinking around 10,000 lumen), all the time. So I want a light that doesn't drop down to lower light levels after a minute or so.
Preferably I want a light that gives out a huge but steady amount of light from beginning to end of battery life.
I don't mind what size it is so long as it can be put on a belt in a holster or similarly portable.
I know that what I'm asking for probably doesn't exist, most flashlight makers seem to want to show off with huge turbo modes that don't last but still, I thought I'd ask. Below I've tried to fill out your checklist.

1) How would you prefer to purchase the light?
Online

2) Budget: An easy question, but you may change your mind after answering the rest! :)
Essentially unlimited.

3) Format:
I want a flashlight (hand held/self contained).

4) Size:
MEDIUM - Holster/belt ring carry. (>7 inches)

5) Emitter/Light source:
LED

6) Manufacturer:
I want to buy a light from a large/traditional manufacturer that is ready to go out of the box.
I would like a light from a specialty manufacturer (Possibly limited run/Custom).

7) What power source do you want to use?
Any rechargable lithium batteries.
7a) If you have selected a rechargeable option
I don't care

8) How much genuine out the front light do you want/need? Sometimes you can have too much light.
There is no such thing as too much light
Burst/Turbo mode Category: Preferably none.

9) Flood vs Throw: Flood covers an area, Throw reaches out to a distance.
Narrow Flood: I want a sharply defined flood area that will project some distance for tasks like trail walking.

9a) Distance: How far away will you typically need to see with this light
Due to my different needs, distance as you know it, doesn't really apply.

10) Runtime:
Up to 30 minutes, but really as long as possible

11) Durability/Usage:
Slightly Important.

12) Switch Size, Type, and location:
Any switch will do.

13) User Interface (UI) and mode selection.
Any UI is fine, but no bloody strobe mode no bloody SOS mode and no bloody beacon mode.
Either that, or a way to not easily activate them or a way to lock them out

14)Material/Finish/Coating
I don't care.

15) Water resistance
IPX4 (Splash resistant) or more

16) Storage conditions
In house when I'm not carrying it.

17) Special Needs/extras:
None that I can think of.

Welcome!
Can you tell us all your applications? Is it just trail walking? How far away do you hope to see with this tool? Would you consider one flashlight for far away seeing and another flashlight for closer needs?

There are multi emitter flashlights with larger battery packs that may suffice, yet still, one should consider using the minimal amount of light needed for the task at hand.

Going to ask @Monocrom to look at this.

Two HUGE issues. 10,000 lumens that don't kick down to a lower level after a minute or two (at most) of use, and small enough to fit onto a belt.

Literally one light comes to mind that will be the closest.... Thrunite TN50. (Obviously I'm not going to recommend a light I don't own.) I have that model, it is very impressive. Soda can sized. Comes with a belt holster. Proprietary internal battery. Not ideal, but currently the best solution for getting its 16,000 rated lumens of output on the highest setting.

Yes, this thing is a little Beast of a light! Unfortunately it's also one of the greatest improvised hand-warmers you will ever encounter in your Life! So, the problem is the sustainability of the highest setting for longer than a minute or two. Not happening.

Technology at the current time, a true 10,000 lumens light that can pump out THAT amount of output without kicking down almost immediately to a much lower level, is going to be huge in construction. Fitting onto a belt? Maybe if the Jolly Green Giant were real, you could fit it onto his belt.

What about that Jetbeam model (M64, was it?) that you facetiously referred to as having "lighthouse mode?" Just wondering on behalf of the OP whether that might be worth a shot.

I actually considered it for a minute, but no. Too long for belt-carry.
Not nearly enough lumens for the OP's needs.

Light house mode as I called it is more about throw than anything else, with a more concentrated hot-spot.

Ah, I see.
I thought I might be overdoing it a bit with my lumen requirement. All I know is I've had a couple of lights that I think were around 2000 lumens and they weren't good enough. I know lumens aren't everything though, so how about 5,000 Lumens, are there any lights that can maintain that?

Can you tell us exactly what your last couple of 2000 lumen lights were? Depending on the manufacturer and brand, their rated lumen output could be much less than what was claimed on the package. Knowing that might make it easier to figure out what might be more practically feasible for your needs.

I'm afraid not. They were both unbranded Chinese things. So yeah, their claims may well be rubbish. The one I'm currently using runs on a 21700 cell and while it is better than nothing, it's not much better than nothing. I need something 3-5 times as powerful at least. I apologize for my vagueness, I don't have a lot of flashlight experience. So far, you all have been very helpful, I'm actually considering the Thrunite TN50 but apart from its turbo S mode of 16,000 (for 80 seconds). I can't find the lumen levels of its lower settings. I might also consider the TN36, but it needs a seperate battery charger.

You were absolutely lied to. No Doubt at all. Those things weren't remotely pumping out anywhere near 2000 lumens.

Also, I have the TN36 as well. You're better off with the TN50.

Basic Google search turned up the following:
(Which I then confirmed after contacting Thrunite.)

Turbo S = Over 16,000 lumens (down to under 3000 lumens after 80 seconds.)

Turbo = 7600 lumens (down to just under 3000 lumens after just over 3 minutes.)

High = Just under 3600 lumens (down to 3000 lumens after 12 minutes.)

Medium = 1157 lumens.

Low = 190 lumens

Firefly = Just over 1 lumen.

Strobe = 2900 lumens.

Runtimes:
I only bothered with the realistic ones.
Med. = 11 hrs.
Low = 50 hrs.

Mains-powered light bulbs are pretty good about publishing realistic lumen numbers, along with being relatively standardized. So here are some numbers for comparison:

Incandescent lamp type/wattage (or the LED equivalent)
* 40W general service: ~500 lumens
* 60W general service: ~800 lumens
* 75W general service: ~1200 lumens
* 100W general service: ~1600 lumens
* 90W PAR38 flood: ~1000 lumens

Thank you everyone, you've all been very helpful. I think I will get a TN50. Though it does surprise me a bit that it still seems to be one of the best in it's category despite being at least a 5 year old design. I thought things moved a bit faster in the world of flashlights. Oh well, it still seems like it will suit me well, so I'm looking forward to getting one.
