The main point is that the efficiency of budget flashlight optics has taken a step forward. POP lites are not really budget lights, but these new ones are.
Excellent information. Very useful.
The optics on the LED Lenser .2 models are impressive.
My Lenser P7.2 and POP lite T34 focus about the same way. The convex lens is not quite focused when the TIR zone is focused and makes a larger disc outside the reflected spot. Unlike with the Ray Bow, the zones are close enough that sliding the head a bit farther forward gives a slightly larger uniform sport with both elements nearly in focus. The optics of my Lenser P14 and P5.2 are similar. It is not surprising that they are similar, as the POP lite is described as having optics imported from Germany.
They all have a bright ring, rather than a uniform disk on intermediate slide. There may have been some progress, because the P7.2 and 5.2 are the only ones that are almost ringless at fool flood.
It would be great to have some of those lenses, or that RB500 for a budget price.
I’m waiting for a POP Lite to arrive from DX, ordered it 9/20/2016.
Interesting. I once got a fake Led Lenser off ebay for dirt cheap but it was pretty crappy compared to the real thing.
Love me some collimating lenses!
Nextorch now also has Fresnel zoomies, though frankly I’m not impressed.
We can add Klarus FX10 to the list.
Lumintop Zoom1:
This fake junk appears to have a TIR lens:
And it has frosted sides just like Lumintop Zoom1. Is it the same lens?…Probably not, this light has 6 mm larger head. Maybe a larger model from the same maker?
Just found this:
Magnetic charging?
And another, JY-859:
Here’s another, SME R218:

ADDED: It can also be found under the name of Yaoming YM-8153.

Cross reference of a similar topic:
OK, now I know when I’ve seen that BORUiT.
Fitorch P30Z looks very similar:
They even seem to use the same lens.
A lot of these look like pretty simple TIR lenses, like what's on my olight s1
Yes, these are pretty simple but not as simple. A zooming TIR has a convex lens at the front (sometimes plano-convex and sometimes biconvex). On the outside the design is different as well, the front lens-air boundary is usually not flat but sloped with the outside part facing forward. Frankly I don’t know why but that’s how they do them.
Overall - there’s nothing special about such lenses but they just don’t tend to be the standard (yet?).
Today I found another few TIR zoomies:
2*18650 variant of “P7.2”:
Headlamp?
And 2 PopLites:
