I have dedomed multiple 219Cs. It’s quite hard as most of the time some of the silicone gets stuck on the phopshor, but with a sharp blade you can just barely remove it.
Tint is very warm (about 3000K):

LTR: 5700K nichia 219B, 4000K 219C with dome, 4000K 219C dedomed. White balance set to daylight

CRI doesn’t seemed to be affected. (Maukka confirmed that CRI doesn’t shift a lot with dedoming).
Throw is about what you would expect: About the same as XP-L Hi but thighter beam. (this is by eye and judging from distance so might not be 100% correct)

Thanks for the great beam comparison. I like that you used daylight white balance and shot all 3 beams together, and that one of them gives a Cool White reference. That all works really well together!

On the lux-rc site I see the following comment:

Nichia 219B MDC with T11 lens overperformed CREE XP-L HI with standard narrow lens almost twice in candelas
OK, they use a custom throw lens which is better than stock. But nevertheless they consider dedomed 219b a good option for throw. Does anyone here have experience with that?
As regular user I would not recommend you looking for lux-rc technologies. You dont compare family car with F1, right? First of all, lux used another leds. I have mensioned this several times – some 219bs have smaller dies (and it is almost unreal to get this leds if you are not able to order full 2500 leds reel). Secondly, he rarely use hi-cri nichias and prefer regular version (which have xp-g2 top bin performance). Third, mbc is not dedome, this is custom dome for better throw without lumens loss. Add custom silicone lens, and now you can compare it with $3 xpl-hi under $1.5 10507.

Interesting, thanks.

It seems there are several people who re-dome leds already:

  • Oveready
  • Lux-RC
  • Vinz
  • (never seen confirmed, but probably saabluster too)

Oveready buys Lux-RC light engines, so maybe one of them buys redomed LEDs from the other?

Also, do you have any info on the custom lens?

Dedome is not something you can be sure in finel result. You can find some old cree datasheet about chemical compatibility of leds with silicone dome – even regular leds require some limited conditions, otherwise output can decrease much faster than expected. Nobody knows how much output you will have after 100, 10 or even 1 hour of light with dedomed led.
Lux dont practice chemical dedome (only mechanical).
Lux applies custom dome to prevent fast led degrate.
Finally – his modules work inside sealed area without oxygen.
Again, I dont feel this information usefull for blf modders – since xpl-hi are available (black flat etc.)
I suppose you can find enough information about silicone optics pros and cons. Most optics manufactures started to use this material 3-5 years ago.

I have never seen Vinz re-dome LEDs. He has a method of removing th green tint after de-doming though (he calls it diamond treating).

There are some modders here who build hundreds of lights per year with dedomed LEDs. I have never read a single post in the last 5-6 years where somebody measured an actual loss of performance of time.

A high CRI emitter can have a significantly off white tint, like this green Oslon which is one of the worst (duv 0.0093) I’ve tested regardless of CRI.

However, as the tint was quite consistent throughout the beam in the test light (Thrunite TC12 V2), it can be corrected with a simple filter (unlike an XP-G3 for example).

Dear maukka, pls. wrote full name and color group of this measured sample Osram Square LED.
It’s CQAR.CC or CSSRM1 ?

Yes, all hiCri led has lower low lm/w efficiency, that ordinary led’s, and these Osram Square series isn’t a “lumen champions”, but has excellent color rendering and (imho) tint (CQAR.CC 4000K 6L group).
If you prefer samsung 351D tint – it’s your choice.

Are you talking about the same Oram in the Maukka test above? If so that thing has a whopping DUV of 0.0093, which is great for making horror films.

both are Osram Square family, both 4000K hiCRI, but Maukka tested CSSRM1 with different color group

Where can I get some of these LEDs?

In Him (Jesus Christ) was life; and the life was the light of men. And the light shineth in darkness; and the darkness comprehended it not.

That is the question many of us are asking as well.

Clemence has not been able to get anymore of them and no one else has been able to as well.

I have a back channel hunt going to look for some but nothing so far.

At this point I am thinking about seeing how large of an order would be needed to get a batch made.

Which one? The Osram or the 219B?
If its the 219B, then I still have few hundreds left from the last GB (both the sw45k and sw40).

You have some of the 9080 219B? I thought you were not able to get them anymore? Sorry, have not ventured out of my own threads basically all year.

Nice, I was not aware you managed to get anymore.

Although it looks like they have discontinued them entirely? No way to have another batch made?

I guess the only real option is the E21A or similar LED moving forward for very high CRI? That sucks since it is so much harder to use.

Actually had a light I am working on now that would of been perfect with the 219B 9080.

There’s a minimum order to meet, hence the last group buy. But I really don’t know how much 219Bs left in the warehouse. I have to check back to Nichia. I personally don’t want to stock them anymore. If you really have to use it then PM me.
Single E21A is the way to go, it’s very similar to 219B in performance and output. Rosy tint is another thing though…

EDIT: Yes, officially discontinued. We got the last batch from last year stock, you can see it from the bin labelling.

Yes, with that many LED’s to split the load you should be ok with 30Q’s. They also have a pretty high Vf so they don’t pull a lot of current.

That said, I would try to get a current reading on them so that you can know for sure since those LED’s are so rare.
