IP-enabled bulbs (or rather, 2.4GHz controlled Bulbs, by whatever protocol) have a bit more nuance to them. A controller could probably at best hope to control a dimmer hooked up to the light bulbs. I've setup my own apartment with the IKEA LED bulbs, which is great for giving more individualised lighting (I use the colored LEDs to provide a dimm red light in the evening to simulate sunset more closely aligned with my actual sleep schedule).
