[GB ended,discussion only] CRI > 80+ NICHIA 2000K-6500K [E21A/219B/219C/319A/144A/757GT-F1(Optisolis)]

ThankYou! Super helpful and appreciated.
Ive been trying, and failing, to figure out how to do that

well… its a drop of just under 15%, or in the case of a 200 lumen light, it would become a 170 lumen light…

if the question is, can you notice a drop of 30 lumens… not very easily

its just another way to “improve” tint that is too yellow
but there is no free lunch… nichia got more lumens by tolerating more yellow lumens… if they had stuck to red lumens, we would still have Nichia 219b, and they give up more brightness…

basically, putting a 15% lumen reducer on a yellow nichia, makes it act like a pink nichia, if that makes any sense
as to whether you would notice, that depends on how you feel about pink lumens vs yellow lumens :slight_smile:

I happen to love pink and hate yellow, but Im neither you, nor normal… LOL

its cheap enough to try, and won’t harm anything… contact lee filters for a sample pack…

oh, and according to maukka, the filter does raise CRI, slightly… see this post that shows his measurements
