We’ll be very grateful to see your test results then. My personal request is how far can we trim the blue spike. Also how the minus blue spike filter affects CRI.
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)
