I got into the hobby this year so my collection is small with just a D4SV2 and D4, but the D4S is significant to the D4V2 in every way from ergonomics to my use cases.
D4V2
SST-20 4000 with stock Fex +1 driver
Pocket rocket with too much spill to evenly light a path more than 20 feet in front of me. The 18350 tube is sooo cute though and it will be a great work light with its magnetic base.
D4SV2
W2 6K with 9A + CC linear driver
Even ramping, power for days of dog walking. I think I can get to medium high (5/7) before the driver switches to the CC, which means that I get an extremely bright, usable, throwy beam for as long as the voltage lasts in the battery without it getting hot and dropping current.
The Osrams run pretty hot. There’s also no way the D4Sv2 is thermally staple anywhere near the top of the CC output - 9A, so 27+ Watts
The nice thing is, in general the anduril temperature ramp is so gentle you don’t seem to notice it
I have a Mateminco MT70 Mini SFN55.2 coming in for a landing in about 2 days.
Got the SamSung 30T’s warming up.
Getting a mean hunch this light will make my favorite list.
FWAA as of now with convoy sw45k swap. It has become my flood edc. Carried in pocket w/o clip and mechanical lockout.
Not necessarily totally new to 2021, buy my continuously tweaked TIR FW1A is still my all time hero. This year it got a SS bezel, LEDIL Leila RS, and FD2 sst20. Nearly perfect.
A shorty tube for the FW3C with cyan glow gasket and tail cap. Apart from the chunky lumpy feeling in a pocket, it is my favourite light for general, bedside nip to the loo type edc.
Edit: Total fail from me having read the OP again, sorry.
