Nichia 219B 4500k D220 9080 CRI Emitter output test by Texas_Ace; Amazing tint and CRI! Output is what you would expect.

Where do you get those green filters? I have several LED’s that could use that.

Lee offered a free small swatch colour sample, it consists of hundreds of its colour gel filter. Each sample is enough for two small flashlights. Just contact your local representative marketing. I lost my colour swatch in the project site. I’ll need to order another

Thanks for the link

Oh, look who the funny guy is….lol

Thanks!

very helpful, thank you

pic is a link to more details:

Considering that a perfect redendering index score happens when the different wavelenght's relative outputs follow whatever given temperature pattern/curve shape, I guess we could even fine tune (maximize) the CRI and tint out of any good CRI emitter with a custom tailored filter.

Cheers :-)

I have oslon LCW CQAR.CC-MR-6L-L2, no any grinnich. Compared with 219B sw40, it is slightly yellowish. I planned to order 7 pieces OSRAM OSLON® Square LED 4000K CRI 95 2W HIGH POWER 3030 GW CSSRM1.BM | eBay with C5/D5 chromaticity coordinate (below of BBL). If C5/D5 is missed, here is guaranted reddish tint https://ru.aliexpress.com/item/OSRAM-OSLON-SSL-80-High-Power-LED-1-3-Watt-LED-BLUE-LB-CP7P/32295974290.html

How about these:

Can’t find info on the chromaticity though, only the colour temperature (3000K)

Looking into filters, i found Lee Zircon LED dedicated filters.

Maybe better to discuss this in Clemence’s topic.

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

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?

I sliced the dome on a 219C once and the throw was pretty good. Although a full dedome has proven pretty hard and it seems that those that tried it were not that impressed.

Personally I won’t dedome an LED due to the tint shift.

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.

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!

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?
