Nice ! I find the light magenta of the 219b more complete ; my eyes are reaching more . The anniversary sale is asking $100 basket .

Caught a sickness . I found out i'm not alone .

Thanks for clarification – yeah it does have min purchase requirement. Great for anyone who would like the trio of two S21D’s 219b & 519a and the M21B GT FC40. This amazing trio still costs less than 1 Olight Warrior (!).

I have not written about the M21B with GT FC40 yet but it’s a game changer also and also recommended without reservation Smile .

BTW the Littokala battery included with the Convoy light tests great with my Opus and performs the same (same brightness, actually higher 5000 mAh capacity) as my Samsung 40.

Last time i bought over $100 in one order from a chinese seller, they decided to use DHL and declare a value over $20 . So $2 of taxes and $23 of fees . And you have to pay with a check true the mail . In Canada, it’s better to do small purchases .

Ouch. For US buyers: I did buy all 3 together and all I had to pay was 9.5% tax. Shipping was “AliExpress shipping” and was free.

Just a warning for potential buyers: Convoy packaging is at best err… “elemental.” I was actually mildly shocked at how minimalist it was. LOL I am exhausting my euphemism vocab. Don’t expect Olight box at this give away price .

Flashlight porn Party . I’m surprised how much I like antique brass, but keep in mind it’s very heavy.
The aux lights are pretty and fun. I bought too many lights at the same time & at this point the color coding helps me to remember which light has which CCT .

Up until recently my favorite walk light has been Olight M2R Pro Warrior. A comparison with Convoy’s Nichia 219b 4500k shows just how horribly greenish the M2R’s Cree XHP35 LED is. (Edge of Olight pic is dark because M2R is a throwy tactical light with bright hotspot, whereas Convoy is floody.)

How does Olight XHP35-HI 4900k handle the pastel leaves? Unfortunately this “errroneous” greenish tint once you see it, is very hard to un-see Facepalm Smile .

No offense, but are you kinda brand new to lights and/or ordering from China? I see your join date is very recent but for all we know you’ve been around for a decade. Smile

I mean this is typical and there’s also some reason to it. Simon actually packages most items very well, even going to the extra small expense of using plastic lip balm snap-lid containers to send things like drivers and emitters and other little bits…it’s an extra step that you generally will never see from any other vendor (except perhaps Sofirn and some other suppliers that do glass lenses or delicate electronic parts). Simon has always been an enthusiast like us and wanted to bring higher quality at lower prices compared to other companies, which he has mostly excelled at over the years. The sparse packaging, lack of printed manuals, etc, is a way to simplify process and reduce costs so that the money you are paying is IN the light and materials rather than superfluous junk like most companies. He brought out the nice white gift boxes for the colored S2+ models some years back but that’s about as fancy as it’s gotten.

Noctigon/Emisar is the same way, for the same reasons. Sofirn does this to an extent although some of their models do have slick printed box packaging and whatnot (manuals, too)…they’re aimed at the larger market but blessedly cater to us enthusiasts as well.

If you’ve ever ordered from Banggood, Gearbest, Fasttech, and many many sellers on aliexpress…often you just hope that anything remotely able to be damaged makes it to you in one usable piece. An example…Banggood will ship drivers without any padding whatsoever (no bubbles, no foam, no box, no case…nothing but a ziploc)…and all that in a thin plastic overwrap bag (they do the same with flashlights, so if they are in a box it’ll likely be crushed in one or more places upon receipt). This is just kind of the norm for the big ball of snafu’d yarn that international china logistics and commerce are. It’s the companies that start to target the US market and/or greater retail outlets that put the money into “shelf packaging”, and we all pay for it…even more when they do that and begin perception pricing.

So it’s nice that folks like Simon and Hank and others keep it simple…imho. To me it’s only a niggle if I may want to gift an item…then I just get a little creative and make it fun for the recipient.

Good points. No offense taken. Needless to say (as reflected from the first two posts of this thread and the coming M21B GT-FC40 impression thread Thumbs Up Smile ) I am a huge fan of Simon’s and Hank’s work.

I’ve mentioned 519a 4500k has a more golden/yellow tint compared to 219b 4500k. Whereas 219b 4500k has negative Duv and therefore has a rosy/magenta tint, Duv of 519a is very very very Smile slightly above BBL line, hence more yellow.

The crop below shows 519a to be outstanding with color rendering still (full pictures of these crops are on page 1 for anyone interested). In actual use (vs pictures), it’s interesting to note that the magenta character of Nichia 4500k LEDs (219b, E21a, 519a) is still noticeable with 519a despite of its more yellow tint, just less so.

Also in actual use, scenes under 219b sw45k’s beam seem to have more depth/layers and objects (flowers against leaves etc.) seem to be more distinct from each other. I hope some of that characteristic is reflected in this picture (compare the lavender plant).

519a numbers are top-notch: Ra 93.6, R9 82, R12 80. I think it’s the more positive DUV that gives the more golden tone versus 219b. I actually like the golden tint with a touch of magenta of 519a very much. Too much magenta like 219b sometimes gets to be… too much Smile .

R9 for the Convoy M21B 219b sw45k is an eye popping 97. That Nichia 219b LED is legendary for a reason. R9 is “difficult” to achieve and anything above 50 is already considered very good, and anything above 80 is top of the class (why R9080 is considered best there is).

For those new to this like me: 2 factors determine beam color: CCT and Duv. Above picture of Nichia 219b and 519a shows how a more positive DUV of 519a gives a more yellowish tint. And a more negative DUV of 219b gives a more rosy/magenta tint.

Below is a comparison with the very popular SST20 4000k in Sofirn IF25a – showing lower CCT’s effect on color, making it more yellowish (and a little greenish). No right or wrong, just different; like the different colors of different light bulbs. Maybe later it would be interesting to compare this SST20 4000k with Nichia 219b 3500k , one of my very favorites because it has yellow tone without the green tint.

But for sure no LED I’ve seen so far could render those lavender leaves like Nichia 219b 4500k. Its spectacular numbers explain this ability: Ra 96, R9 97, R12 79 (holy cow Smile ), Duv -0.0095. As always anyone pls correct me as needed if I make an error.

Thanks Jon – you’ve piqued my curiosity with your posts, leading to these crop comparisons. Smile

On page 1, I had a picture of my living room of Nichia 219b 4500k vs E21a 4500k, showing the two LED’s are for all practical purposes identical. The only difference being E21a is always dimmer than 219b during a run-down from Turbo. I jacked up the thermal limit of the E21a to 60 C, and it’s still dimmer.

Now here’s the lavender crop, showing PERFECT rendition of the lavender plant. The colors are so close I had to go back and forth several times to make sure I didn’t just post the same picture, proving again the only thing that could look like a Nichia, is another Nichia. Innocent Albeit NOT as bright. At any rate, unless there is some other reason I don’t know about, IMHO E21a is one I would bypass on if I already have 219b.

So far I have done comparisons of Nichia against each other: Nichia 219b versus 519a versus E21a, all at 4500k. Now although it’s off topic of Convoy, I thought it would be interesting to compare other famous LED’s at 4000k vs Nichia at 3500k.

First up is the highly regarded Luminus SST20 4000k in a flashlight I love, the Sofirn IF25a, here compared with Emisar D4V2 with Nichia 219b 3500k. The interesting thing with comparison (either by photography, or by back to back real life beam shot of for example my living room) is it tends to emphasize a tint that you might not have noticed before. In this case the green tint of SST20 4000k.

Another observation of last picture above: Although both beams as a result of the lower CCT (4000k and 3500k) are “warm” in nature, the “tints” are clearly different (one is green, the other rosy). And IMHO the tints are different likely because the 2 LED’s have different Duv (the other factor besides CCT, that affects “color” of a beam).

If I have to guess, it would be that SST20 is above the BBL line (positive Duv, resulting in greenish tint), whereas Nichia 219b 3500k is below BBL line (negative Duv, resulting in that rosy/magenta tint that is so loved by flashlight hobbyists).

The trees trunks definitely look the most natural under that 519A 4500k vs the 219B SW45K.

What makes SST20 so nice is that it has such higher throw and lumen output, that you can afford to put a minus green filter in front of it, sacrifice some of the output, but still come out at or above 519A output.

Btw, lavenders are not supposed to be naturally rendered strongly from CCTs at only 4000 to 4500k. Those lower CCTs have less purple and blue content in their spectral balance. It’s why 100 CRI 2700k incandescents do a terrible job at distinguishing purples from blacks. The SW45K is only emphasizing the lavender plant because it’s emphasizing magenta hues in it, at the expense of making the tree trunks and rocks look magenta as well.

If you want the absolute best color rendering and separation, you’d get something with a very neutral duv, but at a CCT that has very good spectral balance, closer to 5000k or 5500k.

Unfortunately the S21D with the 519a went out of stock on AliExpress before I ordered mine, but I’m looking forward to the 219b. It shows as available on Banggood, but costs as much without the battery there as with the battery on Ali. Might be a brilliant sales tactic, be me hooked on the 219 so I pick up the 519 when it’s available laughing.

I asked Simon and he says “the LED is out of stock currently.” If you/anyone is interested in 519a and don’t want to wait it would seem Banggood is the way to go while they still have them in stock.

I highly recommend the 519a also. Whereas 219b has that famous rosy/magenta tint (a result of a negative, below BBL Duv) that every hobbyist loves, 519a has a warmer, more yellowish/golden tone (a result of a positive, above BBL Duv). During comparison, I actually was struck at how different 519a is from 219b. See the hat crops from beam shots of my living room below (thanks Jon) – besides the red hat, notice the background. The window blinds are very slightly off white in real life.

I like the 519a because of how different its beam color is from 219b, and yet it still has spectacular CRI specs ( Ra 93.6, R9 82, R12 80, Duv 0.00091). While 219b has better R9 (reproduction of red), sometimes the magenta tint of 219b might be too much Wink , and 519a’s golden tint provides a relief. In other words, like having different wines or food from different restaurants, all good yet different. I guess it’s called having fun with a hobby. At any rate the pair would make a great great back bone to any collection where CR and /beam color & quality is of prime importance

Jon or anyone, what should we expect when 519a is de-domed? Lower CCT? More throwy? (I think this is what happens to my Olight M2R Pro Warrior when they decide to go to the flat HI version of the XHP35, versus the dome XHP35.) Lumen stays same? Thanks.

We are indeed lucky to have Convoy/Simon and Emisar/Hank.

Dedomed 519a, compared to dome on:

15% reduction in output (not visually significant)
24% reduction in CCT (Very noticeable)
Tint DUV moves below the BBL (Very noticeable)
Hotspot gets smaller. (Very noticeable)

Thanks Jon. The dedomed 519a seems to have similar beam color as 219b 3500? If so what would we gain by buying that versus a 219b 3500k light?

I prefer the lower Tint DUV of 519a 4500k dedomed
.

519a makes about 30-50% more lumens… (depending which CCT is being compared)
.

I like dedomed 519a 4500k tint better than 219b 3500k, otoh, I like the color of 219b 3000k better than 519a 3000k

so overall, the dedomed 519a is brighter, and has better Tint, for my personal preference
.

with dome on, the 519a is a good replacement for LH351d, XPL, and XM-L2. and the 519a is a 9080 LED, the others are not.

specific to a V11r, the 519a produces a much better beam profile (with dome on), than 219b. Because the reflector has an extra large hole at the base, and it produces an undesireable shadow in the spill beam with 219b, and with dedomed 519a:

Below is a crop of the picture above, SST20 4000k in Sofirn IF25a versus Nichia 219b 3500k in Emisar.

Before the arrival of the Nichia’s, I hardly noticed any green tint with its SST20 LED. This is a perfect example of how comparison, whether by photography or by back to back “real life” views, magnifies differences. Nichia magnifies how yellow greenish SST20 is, and vice versa, SST20 magnifies that signature magenta tint of Nichia 219b. The morale of the lesson, for me: if there is a light you like, don’t do back to back comparison with these Nichia’s Facepalm Smile .

The yellow green tint of SST20 4000k covers both the lavender plant and the bark of the big tree with a yellow greenish hue, turning the lavender plant almost all green. Nichia does same with its magenta tint, but does render the lavender plant more accurately. I would also like to note that green tint or not, the Sofirn IF25a remains one of my most favorite lights. It is brighter and for me much more useful in daily use than the Nichia because of its brightness. And when used by itself (without back to back comparison), the green tint does magically disappears.

Probably the most favorite light in my small collection is the Sofirn SP36 BLF with Samsung LH351D 4000k, a very well known and one of the most highly regarded LED’s outside of Nichia. (LH351D is the same LED that is used in the famous lantern Sofirn LT1 BLF.) Known for its high CRI, the Samsung to me stands the perfect middle ground between magenta tint of Nichia and yellow tint of SST20 4000k.

Before comparing Nichia vs Samsung, I thought it would be fun/interesting to first compare Samsung LH351D 4000k versus Luminus SST20 4000k, both in Sofirn lights. Both LED’s have CRI/Ra in the 90’s, but I don’t know about R9 (strong red). Judging by how the lavender plant is rendered, I would guess neither is as strong as Nichia’s R9 value of 80 plus in the 219b series (219b is R9080, the highest Ra and R9 rating possible).

I hope the photo shows why I love my Sofirn SP36 w/ Samsung LED. Without doing photography comparison or CRI consideration, if you were to ask me based on real life viewing which is my most favorite tint overall, it would be the LH351D 4000k. In this particular crop, LH351D is less yellowish/greenish than SST20 4000k, and has more faithful reproduction of the bark.

The LED’s tint has little to do with its R9 rating. 95cri 4000k SST-20s have R9 of 97 (with no additional optics or lens over the LED).
