Which light bulbs - only LED or others as well?

from Philips there are the SceneSwitch lamps. You can set them to 3 brightness levels without a dimmer by turning off and on. They are also available as filament lamps with E27 base

But I have a dimmer...

Should not pose a problem with "dimmable" LEDs. For example, we have also converted our halogen floor lamp (dimmable) to LED. The light color is almost identical....

But I do have a dimmer...

... which does not mean that it can handle the lower minimum load of LEDs.

If the old dimmer needs to be replaced, beware:
Some electronic dimmers, such as the Gira LED universal dimmer, require a (usually blue-coated) neutral conductor as a third connection (in addition to black and brown) in the flush-mounted box for LED operation.

But it works really well with our LEDs. We have two of them.

If only it weren't so expensive... 80€ for the dimmer insert + 40€ for the touch control cover plate.

I would be interested to know if the dimmable LEDs have a shorter lifespan. I have the problem that many LEDs, advertised as "eternally durable," fail on me because they are controlled by a timer switch. Is it the same with dimmers?
