Okay. I ordered one of these. At this price point, it needs to be only about half as good as you describe it

I gotta feelin’ yer gonna be impressed - for the bux in its class IMNSHO, unbeatable.

PS. If ya take it apart you’ll notice that the aluminum LED pill has two well-fitting o-rings that are separated enuff to afford a nice and easy even glide in the zoom head. Little touches like this fer $2. Boost driver and all.

PSS. With an AAA Eneloop it weighs a whopping 32 grams and with a 10440, 29 grams.
A nickel if ya never cared to know weighs 5 grams.

For weight perspective yer standard S68 with batt weighs in around 87 grams. Try hanging that off yer hat brim as comfortably.

PSSS. AAA Eneloop weighs 12 grams. AA Eneloop weighs 27 grams. And a AAA alky (YECH!) weighs typically about 12grams. (AA alky about 24 grams.). So the E522 empty is 20 grams or just 4 nickels.

PSSSS. Corrected Post #4 above to state that it has a boost driver already. I erroneously said that you could install one. Btw this actually puts out a little head heat on even the Eneloop.

What kind of tuning does it need to perform decently?
I suppose a LED swap is a must but I guess that’s just the start.

What kind of tuning does it need to perform very well?

I’ve bought an mcpcb with a presoldered 3000k e21a from virence.com. I am very happy to have this led in a igger zoomie.

Well, ok, there’s a problem with LED choice fur such thrower-flooder, there are very few good matches being produced and even fewer available for a reasonable price in reasonable quantity.
There’s intrinsic conflict: efficient high output flooder needs a large die. Dome helps and so does flip chip. Thrower needs to be small, flat and no flip chip.

I have less than zero knowledge about the subject but i think for a zoomie thrower the amount of light directed forward vs outward is important too, since zoomed in a significant amount of light gets wasted.

Yes, that’s a good point.
Though most modern LEDs don’t seem to differ much. I just checked Luxeon Altion Intense, White Flat, Luxeon Z ES and SST-20. They all seem to have about 87% intensity at 30 degrees. That’s not exactly the right parameter, what really matters is the total output from 0 to whatever the lens collects when focused. But it’s close enough and much simpler to gather.
I remember that Oslon SSL 80 directed light more forward though.
ADDED: and a few more Osram emitters do this as well. Seems like a cheap pre-collimator.
ADDED:
Osram LUW CN7M looks really zoomie-friendly:
