Convoy S21D w/ legendary Nichia 219b :) - Review & comparison w/ Nichia 519a, E21a & other lights with Nichia LEDs incl. Emisar D4V2, Convoy S21F. (Summary & measurements on P. 1)

For around the house, I reach for my S21F the most

The star of the show is the LED, and here on S21F’s 5700k end (measured 5000k) we have quite a doozy :slight_smile: . Beam color is somewhere between the extreme rosy tint of 219b 4500k and the sunset-yellow tint of 519a 4500k. It is “creamy” for lack of a better word, meaning off white but not too yellow like 519a.

This comparison is with another 5000k LED, Nichia 219c 5000k in my Wurkkos TS21. 219c 5000k is a great example of a “daylight neutral” LED and that’s why I like it. In comparison, 219c’s color is cold/white-blue whereas 519a 5000k is warm/creamy golden. Not one is better than the other; they are just different. Although I would admit I much prefer 519a.

Secret divulged: That surface of the palm tree is a great way to quickly check the LED’s tint. 219c 5000k turns its color more greyish, 519a shows shades of brown bark.

Thx for the beamshots!

We’re so lucky to get that 5700k bin!

I have trouble believing the 519A photo is truly around 5000K–it appears much warmer than that. Could you compare the two lights on a white wall, not scenery?

Sure - pics will be coming.

IIRC stephenk also reported 5000k in his excellent review: https://www.stephenknightphotography.com/post/flashlight-review-convoy-s21f

Got the S21D today. For fun, I’m attaching a beamshot pic I made along with a few others.

That Convoy M3-C 70.3 HI 5000K looks pretty green.
I ordered a Convoy with a 70.3 HI 3000K.
I hope it has a better tint.

why not 4000K? I didn’t know the 5000K would be so green. If I were to order again, it would be 4000K.

I like warm tints, but I heard that 4000K has a nicer tint than 3000K or 5000K after I ordered the flashlight.

Fantastic beamshot @raccoon or is it @DunninLA1? I hope everyone who is new to flashlights and Nichia gets to see this picture.

I (and likely most Nichia fans) could identify the famous and standard-setting 219b 4500k with my eyes close :disguised_face: . That rosy/magenta tint. GT-FC40 is also nearly automatic - tint is halfway between 219b and 519a, and I think CCT is 4500k (not 4000)? 519a I had to check to confirm because some low CCT Nichia’s like 219b 3500k could look like that; but that sunset yellow tone is clear.

These three LEDs IMvHO are the very best that technology could offer today in terms of objective and subjective color rendering. As for the two green monsters: reason why I think beamshot or at least a comment about whether tint is green is extremely important in every professional review. @DunninLA1, especially for any Cree XHP70.x LED, I would not buy until I see a good beamshot from a reviewer.

Yes great picture above!

Is that the S11 with FC40? I was debating to get that light or M21B/F lol

I just received my B35AM S21A today and was wondering if it’s normal to have a small yellow hotspot in the middle?

thanks!

To answer prior question, yes, the GT-FC40 4000K is the S11. Beautiful beam spread, nice and floody. The only “thrower” I have is the M3-C 70.3 HI, as I don’t really ever need a thrower.

I am particularly impressed with the FC40, it’s so versatile and warm. Of course they all look fine, and generally white, except for the 3500K, which is for lighting a painting in a dark hallway at night, when used by themselves and not put in a beamshot lineup.

I think all of them are on lowish settings… probably around 10%, which makes the 70.3 greenish tint worse than at 35%. Background is a creme white linen sofa. White balance is whatever iPhone SE 2021 decided. The 219b in the S21D is with 30 degree beaded optic.

Incidentally, when I combine the beams of the 519a 3500K and the 519a 5000k, it looks a lot like the FC40 “4000K”, which I think is more line 4200K.

Just like to add that if Dunning’s GT-FC40 is the “4000-4500k” version from Simon/Convoy, it likely measures 4500k CCT.
@jon_slider in case you like to change the labeling on Dunnin’s beamshot.

Yep GT-FC40 4500k is special. Nichia like color rendering, with more output and throw. And more versatile because of that. I remember reading @stephenk 's excellent review and knew right away it’s a no brainer.

OK, done :wink:

Hey guys, can you check out my pics to see if this is normal? It’s a bit hard to see but if you zoom in, it looks like my LEDs are damaged cuz there’s a yellow hotspot, is this normal? lol

B35AM S21A

why do u think that beamshot idsn’t normal? looks ok to me

@snfx you mean like below? Hotspot has a colored center, bright white ring, then halo? Yeah I’ve seen it in white wall hunting of single LEDs with reflectors and throwy beams (and not on multiple LED TIR optic for example).

The 2 parts of the hotspots are both extremely bright and more or less indistinguishable in actual use when beam is enlarged onto subjects further away. AFAIK: as long as it’s not a dark donut hole (focus problem), I don’t think it’s a problem.

The one thing that got my attention is why your beam is so green? Is it taken with fixed WB 5000k?

Maybe I’m just white-wall hunting but right dead center where the bullseye is, there’s what seems like a burnt spot…

Can’t really see it far distance, only close-medium distance…

I don’t know how I feel about B35AM, maybe I’ve been spoiled by 219B/519A lol, could just be a defective unit :frowning:

Isn’t the B35AM, basically 4 E21A emitters?
