I never got used to "cool white" flourescents. The "delux cool white"
was better. I've switched virtually everything to LED now and I use
ONLY daylight. Took a bit of getting used to, but the light is SO much
more natural - and SEEMS a lot brighter for the same lumen output
because the human eye senses bkue light much better than yellow

Yes. Blue and yellow together make white.

BTW, I first saw that with some "color changing" Christmas lights. These
used blue and yellow LEDs connected in opposite polarity, so the color
could be controlled by controlling polarity. If both LEDs are lit
(actually alternating fast), you get white. In the same way red and
green make yellow.
