We have about a dozen Phillips Hue bulbs installed, both color and warm white filament.
Once the the Phillips hue app is installed Alexa can pair with it.
To turn lights on you say " Alexa bedroom lights 30%" and the lights come on at 30%.
To turn lights off say "Alexa living room lights off"
Or the app is on the wife's phone and she can control; on, off, %, and color from her phone.

I don't think we will install them every where, they do have their place.
