It'd be interesting to include the D4S with W2.1 as well. Andreas has posted in the German forum (https://www.taschenlampen-forum.de/threads/manker-u22iii-sbt90-2-led-5000-lumen-review.81358/) a comparison showing that the U22 III has a lot of spill, more than the D4S(!). In the same review there's a link to another post presenting beamshots of the MK37, showing it also has lots of spill. This is a surprize to me, I've seen several posts saying TIRs produce less spill than reflectors.
I LOVE the D4Svn but if I add it then there are so many other Osram lights that wants to join the party...
