We're having a new fitted bedroom installed and beforehand, I want to make sure we integrate some kind of iPhone/Smart switch compatible lighting. I've seen several videos but none really allow me to understand whether it's totally pointless or not.

Firstly, does it use more electricity? I'd imagine the smart tech is within each light bulb, and therefore electric would permanently be being fed to the light circuit, in the same way as a standard switch would be left in it's powered position?

I like the idea of having the bulbs nearest the bed dimmed to say 30%, but the main lights at full brightness or 75% etc, all at the press of a button.

Also, it looks like I'll need a wireless hub that works with the lights permanently plugged in to the router to make it all happen?

In other words, is it worth it or should I just stick with standard lightbulbs and switches?
