Hello everyone,
In our bathroom, we plan to install a suspended ceiling with swiveling recessed spots featuring GU10 bases. Now we have a question about the LEDs: what are the advantages and disadvantages of 12-volt versus 230-volt LEDs? The only thing I know is that 12-volt LEDs require an LED driver or transformer. So 230-volt LEDs should be more cost-effective since you can skip the transformer. Or do 230-volt LEDs have a shorter lifespan?
For example, Philips Hue bulbs are 230 volts, and we want to install two of these in the ceiling of the bathroom (one above the toilet and one above the bathtub). That seems to be another point in favor of choosing 230-volt LEDs for the other spots, right?
Thank you very much for your answers.
PS: In the kitchen, is it really that important to use LEDs with a CRI (Color Rendering Index) above 90 for the countertop area?

Can I install a 230V dimmer as a flush-mounted actuator behind the light switch? That doesn’t make much sense. Just use a push button with an actuator right away.

What should I pay attention to with low-voltage spotlights to make sure they can be dimmed by a 230V dimmer? Make sure the manufacturer specifies or approves that function for the model in question.

The recommended dimming actuator for me was the Eltako wireless universal dimmer switch FUD61NPN-230V. We have installed Eltako actuators in the sub-distribution panel with a push button in front. That works fine.

(Series connection of multiple spotlights)? Is it really series or parallel? Because a separate transformer indicates a parallel connection.

Really series or parallel? Because having a separate transformer suggests parallel connection. That’s correct. Series connection is only possible with a central transformer and drivers designed for it.

That the manufacturer advertises or approves the function for the model. Addition: The dimmer must of course also be suitable, as @Mycraft points out. A resistor-based dimmer won’t work, but a leading-edge dimmer probably will.
