This bulb is fully compatible with the rest of the HUE range, so it can also be dimmed and switched with all accessories.
However, I would like to say that I no longer use this bulb because it is very susceptible to EMC.
Every time I close or open my blinds with a button, this bulb switches on. This is not the case with any of the other 20 or so HUE bulbs in my household.
The light colour is golden white, i.e. a very warm shade of white (analogous to the former carbon filament lamp). When dimmed, it becomes darker, but unfortunately also somewhat cooler in white.
