I tought i saw an Alien.
My “2021 lights” are not from 2021 
My most used lights are the:
- On The Road 311 (EDC, modified)
- Olight Warrior Mini (EDC)
The one that surprised me the most was the Imalent MS18, which is not from 2021 as well.
2021 flashlights that I was happy to have:
Lumitop FWAA
RovyVon S3
Another thread trying to drive a wedge between children 
M21B GTFC40 ~3200k
Or
Manker MK37 SBT90
Best: Zebralight SC64w HI. Incredible quality, size and beam.
Favourite: Malkoff MD2/M61 with Hi/Lo. Just love this one, around the house and in the forest. Usually carry the Zebralight as back-up.
Most fun, and best EDC: Emisar D4V2 SST-20 4000K 95CRI. Can do it all. Beautiful beam and tint. Most carried.
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
Updated till here :D
Convoy L21B
I’m surprised that it only has 1 point
Nitecore TIKI (a RovyVon Aurora A5 clone clone or vice versa)
Wildtrail WT90 for sure.
I’ve decided that the Thrunite Catapult Mini is my favorite flashlight I got in 2021. I’m impressed by it every time I pick it up.
Sofirn IF22A
Emisar D4Sv2 W2
Emisar DT8 XPL Hi 4000k
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.
Wuben E6,
Being a pocket rocket that can powered by 14500 or AA battery
Convoy M26c with GT-FC40.
Wildtrail WT90
Power, style, a big that's surprising lightweight.
Zebralight SC700d still at the top of my list.
This one is up there for me too. Very pleasant beam and tint.
Convoy L21A with KW CULPM1.TG
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.
