@dansup I prefer warm white myself. Firstly because they're more reminiscent of the old incandescent bulbs. And, more reminiscent of actual sunlight, so they feel more natural to me.

But as someone with a retinal condition, I have since discovered that a) blue light is actually *terrible* for your retinas. One of the worst things you can do, in fact. Which is why you get blue light filters on screens and spectacles and such, and b) cool white emits a lot of blue light. The cooler the white, the more blue light, in fact. Which makes sense, when you consider what a blue light filter does: it makes things appear slightly yellow (i.e. warmer). :-)
