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
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.
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!
