It’s a great question, much discussed in the forums. I don’t think there’s one clear answer, it tends to come down to your own specific needs and personal aesthetics
The following topic tends to come down on the side of bulbs:
So whats everyones opinion on the best light bulbs to use with ST? This will be my first time to use any kind of Zwave or Zigbee lights.
Any info given is greatly appreciated along with pros / cons. Last, are the lights normally brighter than the standard florescent lights?
But this next topic, equally active, tends to come down on the side of switches:
It depends on what (where) you want them for.
The biggest advantage of smart in-wall switches over smart bulbs is the way that the switch works with both the light and the ST hub. If you turn on or off the physical smart switch, you can turn it back on or off with ST. (And if you turn it on/off from ST, you can still turn it on/off from the physical switch.) As well, the smart switch still functions like a normal switch even when ST isn’t working.
With smart bulbs, if you turn off the bulb from a fixture or switch, the bulb is disconnected from the ST “network.” That means that ST can’t turn it back on. In fact, ST can’t even find the state of the bulb, so it’s almost as if you just completely unscrewed the bulb. In other words, for things to “work” properly, you can ONLY use ST to…
Both topics should be helpful to you.
Also, if you are interested in combining smart switches and smart bulbs, this next topic should be helpful:
Thinking on a big move to Hue lights, the real question is - what switches to use with them? If they’re all automatable via ST and other devices, do I really want to put them all on controllable switches too? There’s the advantage that I can arrange to ensure those switches are on so that the the Hue bulbs would be too…but it also leaves open the ability for folks to just turn them off and leave them off.
Hmm. Thoughts?
