Hello Yurii, the S21D is a close range flooder with top class CRI. Your next light IMHO should be something completely different, to give you a range of useful lights, so another vote for Wurkkos TS30S with SBT90.2 LED. ~1 km throw, ~4000 lm, still fits in loose pocket. Nothing at $60 comes close.
What’s nice about this light is the beam quality with SBT90.2 (why it’s such a hot LED lately): it’s a super-thrower but with good spill and larger hotspot. CCT of ~5100 is warmer (nicer) than most throwers that tend to be ~6000 CCT. The more I use it, the more I fall in love lol. You will be shocked (and pleased) by the distance it covers and how bright it is. I posted my measurements here if you’re interested: Wurkkos TS30S + monster LED SBT90.2 = $60 4750lm 1km SUPER-Thrower. Comparison w/ TS30S Pro, Olight, Nitecore, & other monster lights. :)
Another vote would be for M21B, F, or E with GT-FC40 4500k (High CRI, medium thrower, medium flooder). But this would be the third light. I would vote for TS30S above M21F, partly because you already have S21D. Happy Holidays and stay safe.
