The TN35 is a nice light, but it's not a thrower.
The LED has a very large die area, that makes for a floody beam even with the big reflector. Under realistic circumstances, you will not get 500m of throw out of it.
I have a TN35 (~2500 lm - 70,000 cd) and a saabluster modified TN31 (~900 lm - 500,000 cd). They share the same external dimensions. If I'm going out for a walk and am willing to bring a large flashlight, I will usually prefer the TN35 over the TN31, because a specialized thrower is not all that useful for most purposes.
I quite like the TN35. It's very solid. It's got well spaced modes including a nice moonlight.
I like the control ring + tail clicky user interface, too. It offers momentary, it lets you select your desired mode before turning the light on, but is simple enough that people immediately get it when you hand them the light. Personally I could do without the strobe, but it doesn't annoy me since it doesn't get in the way.
What I don't like about it is that the body diameter is a bit too large for me to hold comfortably in an overhand position, which makes the tactical switch a bit less useful. But that's the price you have to pay for 3x18650.
Granted, time has marched on, LEDs have gotten a bit more efficient since the TN35 was introduced and flashlights are driven ever harder on turbo mode, but 2500 lumens is still a hell of a punch. I remember when we got excited about LED flashlights that were rated 200 lm but actually put out like 150.
$70 is a good price. I paid $105 for mine about a year ago (new from thrunite's web store), which I considered a good price back then.
