Neutral tints are always one brightness bin behind cool white. Warm tints are at least two behind. Without getting technical, I just think of it as neutral being a tad less bright because they ” took out” some blue. Same for warm. They can’t add more desireable light, so they “block” part of the spectrum of light they don’t want emitted which makes the overall tint warmer.
I may be mistaken but I think what causes difference is the amount of phosphorous. The less there is the bluer the tint and the more there is the yellower the tint. Naturally the phosphorus blovks some of the light which is why they are less efficient. Now let's see who is the first to correct me. :p
They just look a lot better. Lights are getting so bright that you can sacrifice a bit on that end for a better light. You would never even be able to notice that small drop in brightness unless you had them side by side anyhow.
I concur. My PA40W i may be slightly dimmer but as you state it not hardly noticeable. Plus I like neutral/ warm for the most part.

Isn’t it more the other way around? The LED die starts out blue and then they add “ingredients” to alter the color tint. The variation in the process is what creates the varying degrees of warmth.
Thats the way I always understood it.
The way I understand it is the yellow phosphor converts the blue die’s already emitted light and energy into light therefore balancing out a naturally blue light into something more in the middle, with neutral and warm tint LEDs having a more or different mix of phosphor on them. That said, I find blue or bluish light somewhat useless outdoors where not white walls are around to reflect the light. Like many say, neutral and warm tints just look better in for general use and I tend to agree with that. Also, I always find it funny people complain more about greenish tint cool white LEDs thatn bluish ones…if you think about it, the human eye sees the most shades of green which is why night vision is green…when it comes to extreme cool white tints, I prefer greenish over blueish or purplish ones if only that I think they look warmer and again because of the whole human eye seeing the most shades of green thing. That’s my 2 cents on LED tints.
