TK20R: Does this light throw like the original TK20?

[Lloyd H.]

I'm considering the TK20R. I have an original TK20, which IMO has the best color led and is a great thrower.
How does the TK20R compare?
Thanks in advance.

 

[letschat7]

Interested also.

With double the throw, the TK20R throw should be notable

Are you talking about the TK20R V2? Because that throws like 480 meters.

 

[Lloyd H.]

I am asking about the TK20R v2. Let me clarify, I know the lumen output is substantially more than the original TK20. I'm wondering if the reflector is the same i.e. smooth, tighter, a thrower vs the "orange peel" reflector, or wider reflector that gives more a wall of light similar to the LD41.

Ah, this is something that I think is very misleading in product info. Going off the chart above, it says 24,000 candela. The TK20 was something like 6000 cd if I remember right. So you think wow that new light is really a thrower.

But that doesn't tell you what the beam profile is going to look like.

Instead, figure out cd per lumen. So 24,000 cd / 1000 lumen = 24 cd/lm. (don't you love it when the math works out easy? )

Now the old TK20 is 6000 cd / 150 lm, so it's 40 cd/lm.

That means, lumen for lumen, the TK20 has about 1.7 times the throw.

That matters because the "floodier" the beam is, the more light is hitting the foreground, and that makes it harder to see in the distance, even though technically there is more light hitting the target downrange on the new light (24,000) vs the old light (6000).

The old TK20 topped out at 125-150 meters. I have one,great light and tint. The new version hits 475 meters so much more than twice as far. She's a thrower!

Yes, this is what I'm referring to. The beam profile.

 

[thermal guy]

The new version will be flooder then the original "not a pencil Beam" but you will be able to see much further.

Sorry are you saying the old TK20 has 1.7 times the throw as the new one?

 

[Stress_Test]

Lumen for lumen, it has 1.7 times the throw. If the new light could be set to the same lumen output as the old TK20, the TK20 will out throw it.

Ok I see whats screwing me up. The listing above for the TK20 is not V2.
V2 is 57000 CD Thats what op was asking about Ok I'm good now

 

[mikekoz]

I always wanted to get a yellow handled TK20 but never did! Too bad the TK20R did not have one. I love black on yellow!

Yeah, that's Fenix's pesky 'V2' thing. Not only does it contribute to confusion, but often the V2 lights are sufficiently different from V1 that frankly, they should've gotten a new model designation entirely. I've learned that with Fenix, always gotta look for suffix.

EDIT: Remember the LD-02 (which I have / use)? V2 could hardly be any more different from V1. Totally different.

 

[letschat7]

I had this problem when buying E01. It was totally different than I expected.

That's the one that I have currently. Great light, great thrower, and the yellow on black was an easy choice.
