Yes only one single convex lens. I don’t have a light meter, however in my “eyeball” ceiling bounce test it does appear to have less output when zoomed in to spot, compared to out wide at flood.
Well, no beam shots yet… The first thing that struck me was it’s size, it’s is way smaller than it looked in the photos.
I don’t have a light meter but this thing is really bright on a 30Q. I had to use a magnet on the tail for the 30Q because of the battery length issue (it uses a USB charging type cell that is longer than usual, and the battery compartment was made longer to accommodate it, making it too long for usual cells)

I compared it with my low tech eyeball ceiling bounce test and it’s just as bright as my BLF A6 (no spring bypass, so probably around 1300lm) Also as bright as my new 1380lm Litesam PS16. I’d say it’s putting out at least 1300lm on the 30Q.
I love this light! The zooming action is sooooo smooth and “just right tight” the beam pattern is perfect, no rings, artifacts or dark spots throughout the entire zooming travel. The flood beam is great… just a big smooth even perfect circle of light. The tint is on the cool end of neutral and it’s pure white. No yellow or blue at all. The UI is excellent. The switch is excellent, it has great knurling and feels nice and solid in the hand.
The only things I would have liked would be a flat stainless “Foy” bezel. (I’m not too fond of the crenelated bezels) Love the stainless bezels. Also the head could have been made a bit thinner, it’s way thick at the front surrounding the lens. At this size they could’ve put a bigger diameter optic in it.

I’m real happy with this light, it’s hands down my best zoomie right now, and really awesome with the Convoy 18350 tube and Aspire IMR 1100!
EDIT; this is actually the Jaxman tube, which is slightly longer than the Convoy.
But look at that huge zooming movement, they used a very shallow (long focal length) lens resulting in tons of light loss when zooming in (so a small hotspot). Not all is bad about that though, the flood will be very wide.
Sorry about that I was wrong. I thought those flaps sticking out on each side under the head was for twist operation with your thumb, but now with closer inspection I see that isn’t the case. It’s just a normal twisty.
