First mentioned here: 【convoy】SFT40 5000K back in stock (sufficient) - #8329 by Simon_Mao
Been holding off on getting the S21D and waiting for this new one (maybe called S21F?)
I hope it’s not using the e-switch ramping driver - because that would be a big downgrade for me.
As much as I love the H2, primarily because of its weight IMHO it’s not necessarily a good gift for muggles. For us it’s ok because we know its 219b beam color is unmatched and so is the sustained brightness, but a muggle wouldn’t necessarily appreciate the light the same way.
If it’s not a self gift 
and for muggles, I am thinking Sofirn D25L (I have this, a little green but very floody and the perfect headlight for work around the house) or Sofirn D25S.
BTW I’ve found headlamps above 4 oz to be heavy enough that a headband with headstrap is required. This list includes my Coast, Fenix, and the 2 Convoys H2. The 2 Sofirn’s are below 4 oz and very comfortable to wear. Only negative is it’s micro USB or whatever the name is, and not USB C.
I ordered the optic pack for the S21D to try the 10 degree clear since I originally got the 60 degree option for mine. I also couldn’t resist adding the sm453 MAO S2+ to my cart lol
Yes the 10 degree clear TIR is my favorite lens for S21D.
More throw yet still floody enough.
Can’t go wrong with another Convoy, especially one with MAO finish 
.
I really like the MAO finish of my M21F with Nichia BAM.
The hanklight in the picture is beautiful!
If the MAO S2+ had a BAM version, I would’ve definitely got it.
Fingers crossed for a MAO version on the new S21D lol
Thanks - that copper D4V2 sure is a pretty face .
Yeah I don’t really need another light, but felt like the BAM led is “collectible” class.
Unfortunately per Simon new S21D is only black for now.
what y’all think about tint ramping 519a 2700k de-domed with a 5700k domed?
One issue I can see is that since 1) angular tint shift makes the hotspot of a light warmer, and 2) this combination has throwy warm emitter and floody cool emitters, the resulting beam profile will have EXTREMELY bad tint shift, with an orange center and purple spill.
I would recommend keeping all emitters domed or dedomed, or to mix low CCT domed with high CCT dedomed.
I disagree. The rosy-purplish “goodness” is revolting even for some flashaholics. The more creamy, sunlight-like tint of the 519 is easier for the eyes and easier to exaplain as a good thing.
Very interesting discussion as always, but could you explain the part I underlined?
Domed 519a (with the dome causing tint shift no?) has higher CCT than a dedomed 519a, so shouldn’t it be “angular tint shift makes hotspot of a LED/light cooler”?
I believed Hank went with this configuration so he could have full range of 2700k dd & 5700k domed
I was disappointed the Nightwatch Chaos is not available to buy for Xmas gift, but I think this Wurkkos TS32 would more than ease the pain.
14000 lm of Nichia goodness from twelve 519a’s 
in a soda can light. What I hope to use it for is to light up my front garden for viewing or night photography for example. A floody pattern of light AND a lot of light even for short moments would be great.
No doubt Wurkkos has been on a roll, releasing some great AND compelling inexpensive lights such as TS30s and TS10 (let’s not talk about TS21 lol ). I once thought Wurkkos is just Sofirn’s sidekick little brother, but somewhere along the line they’ve become a force to be reckoned with.
Angular tint shift refers to variations in tint as a function of angle, within the same emitter. It does NOT refer to the CCT change going from domed to dedomed.
Domed LEDs tend to send bluish light forward and yellow-green light to the side. The emission collected by a reflector/TIR into the hotspot is mostly the sideways emission, which is warmer than the average/integrated CCT of the emitter, hence a warmer (and greener) hotspot.
If you are ok with angular tint shift, this is a completely fine configuration. If you care about beam consistency like me, this is not the way to go. It's all up to personal preference.
Thanks very interesting; I think I got it now. Central is warmer but the integrated CCT is higher.
BTW your description fits exactly behavior of SBT90.2. I’ve always wondered why there is a slightly green-yellow central spot.
One more question pls - if I understand correctly: The dome causes a tint shift and that’s why in the 519a LED, de-doming lessens/eliminates (?) the tint shift? If so… why does my dome-less E21a has a “worse” tint shift than the domed 219b? Or why does it have a tint shift at all? TIA
That's an excellent question! Most LEDs, including the 519A, have a very uniform light-emitting surface: the intensity, CCT, and tint is consistent across the whole die. With these LEDs, dedoming reduces angular tint shift considerably, virtually eliminating it when paired with a good TIR optic.
The problem with E21A is that the light-emitting surface is not uniform. The intensity, CCT, and tint varies across different parts of the emitter, so the tint shift is going to be bad whether the emitter is domed or not. The only way to eliminate tint shift in this case is to run it as a mule, or to use heavily frosted optics to blend the beam as much as possible.
Y’all prefer boost driver or dual-channel
So this beast is here. It is unfortunately out of stock on Wurkkos web site now but apparently should be back later this month.
Although it is a Nichia I think I will post my impression on it on a separate thread as it is a completely different form and style of light. I have some lumen monsters/super throwers with new Chinese LED on order (Haikelite HK05, JKK76), maybe I will compare them together, not just output but the crucial beam color and tint.
What’s special about the light is it’s a result of Terry @ Wurkkos working with Budgetlightforum HERE, so yes this is a “local” product. There is a TRULY fantastic review of it on 1lumen if you want to read about it HERE .
