The biggest problem with all of these things, is there are too many different ways of measuring their output. And most
ALL of them are overly optimistic about their actual light output. And as this video below shows, Amazon is probably the worst regarding false advertising on these things.
Many are overrated by as much as 98% or more. So it really doesn't matter how much "research" you do before you buy, you're pretty much being misled and lied to at every turn. And are totally at the mercy of luck, as to the brightness you actually get with one of these things.
Still, overall the larger models tend to be somewhat brighter than the smaller models...... And
ALL of them are a whole lot brighter than what was available for the same cost just a few years ago. So all things considered, most are very bright for the money. Buy the one you like, shine the thing in your backyard at night. If you're happy, you made a good purchase. That's the bottom line.
And all of this is why that it just makes sense to replace the old incandescent filament bulbs on well built flashlights, (like the older Maglite's), with new, modern, low cost LED bulbs.
I was just at Harbor Freight yesterday, and picked up one of these below. It's well made for the money. Extremely bright. And it's light, and nicely sized for the center console of my Jeep. That's all I need to know or want.
You can overthink a lot of this. And when you're stuck on the side of the road at night, you're not going to be arguing with yourself about getting the one with 2.00067% more light output per dollar. You're going to be happy you have it, and it works. And that's pretty much going to depend on the quality of the batteries you put in it.
