Indeed, if you want RGB with more power than just aux LEDs, it might be a good choice (althout RGB has just two brightness levels). It's also a great high CRI + UV candidate (alternatively you could consider a dual channel Emisar D4v2 with 519A and UV).
Get it with the additional 18350 tube and optionally magnet in the tailcap. Costs more or less the same as the MiX-7, but only comes with two channels and has no internal charging. On the other hand it will have Anduril.
