I’ve looked at lots of different type of color changing bulbs, but I haven’t found ones that go up to 5000K (cool white) and will either turn on at that color or retain that color after turning off. Philips Hue white ambiance bulbs would be my pick, but they turn on at a more orange color (warm white) and have to be changed to the cool white color.
I’m looking for something that’ll fit what my family prefers (cool white at 5000K), but will also be controllable (color temp, dimness). The closest I’ve gotten so far are the Ikea Tafridi bulbs since they retain the white color after turning off, but they don’t go up to 5000K so they’re not as pure of a white as I need.
I think LifX may do what I need, but the pricing on those is steep and I’m hoping there are better options I haven’t found yet.
