4000K has been perfect for me. Not too yellow, not too white. It’s bright too

Ditto. Perfect working light esp in kitchens, laundry yard.

if you have few light switch you can have 2 different color sets.

if you only have 1, you can install E27 downlight casing and use Philip sceneswitch which has 2 colors in 1 bulb when you want to change color just flip the lights off and on again.

but next time you turn off it will reset to default color. so maybe abit troublesome.

Sceneswitch also has another bulb that has 3 levels of brightness.

i think daylight is more of a balance for you.

do not put 3000k in your living room, it will make your house very dull and making you tired easier. but best install in bedroom.

recommend 4000k for your living room/study room. best for eyes and comfort optimum.

mine, i put mix of 6000k and 4000k in my living room.

<=3000K actually healthy in the sense that we go to sleep easier. It's the overly blue that keeps us awake past the sleeping time.

Working area or kitchen should use 4000K.

>=4000K for drive way, porch, balcony, dry yard, etc.

Off topic but related to lighting, try to use f.lux on Pcs/Mac. It will adjust the ambient screen lighting better to induce a good night's sleep.

There's an option to pair it with Philips Hue lights and or Philips ColorKinetics Intelliwhite fixtures on your home network.

Color temp ranges (can be expanded to 9300K by tweaking options)

This is what it's set as of 9:25pm:

It is not for sleep easier. More important is on your eye when you get old.

If you expose long in high brightness like over 5k or crazy 6.5k, you will have problem with seeing at dark when you get old.

It will be too late when you knew it.

Your eye is already long enough to expose daylight uv for 12hr. Don't get another 6hr at night for crazy brightness.
