I have an electronic switch, not a dimmer, but is electronic without a neutral, the 8 x E14 bulbs are not dimmable,
but to me they seemed to work OK. However they gave my daughter a headache, the switch went faulty and was removed, and daughter has stopped complaining. As to if due to electronic switch can't say.
These two bulbs,
are both G9, the small bulb had a shimmer when on with the electronic switch, the larger one did not, and when one failed and I opened the bulb I found a large smoothing capacitor inside, nearly as big as the smaller bulb.
I find on/off setting on a smart bulb reverts to on when switched off, but the dimming setting seems to stay as set as does the colour changing setting. I am setting in my bedroom typing this which has one BA22d bulb and three smart GU10 bulbs, the latter all switched off so as not to attract insects through the open window.
I do have dimmable lights in the kitchen,
they work well as counter top lights, and at full 22 watt output it is a little OTT. I fitted them as originals failed, and the light strip was on offer at Lidi, I don't know why I bothered, as wife rarely turns them on, however also rarely see counter top clear, may as well just fit more cupboards in the space.
We do use the display cabinet lights
but only because I have set a timer so they switch on in the evening to light our way to main light switch should we dose off watching TV. Either side Ikea lights, centre another Lidi strip light. The two to the left are colour changing.
Top of stairs also colour changing
it seems not to attract insects so much set to colour change, and with just centre lamp switched on it is enough to see up/down the stairs without waking wife if she has left bedroom door open. But normally use all bulbs
which lights the stairs and landing well.
As you can see a fair few lights have smart controls, bulbs, switches, and relays, as to if useful or a gimmick is another story, the landing lights very handy with voice control when I arrive at bottom of stairs with a cup of coffee in each hand, it has reduced coffee spills. But else where rarely used, the remote control used for bedroom lights, but rarely use the app on phone, takes too long to select the app and use it, easier to use a wall switch.
And this goes for dimming lights, how often will you actually use it once the nobility has warn off? Unless automated we tend not to bother, sounds a good idea when we talk about it, but our kitchen is poorly lit by 4 x GU10 lamps, and we have three other lights, two over counters and one in the cooker hood, all three only switched on when my wife want to show off to friends. So what is the point?
