Which dimmer to control 230V LED bulbs

Which Velleman dimmer (in combination with the K8006) can I use to dim 230V dimmable LED bulbs?

Most LED bulbs are not dimmable.
This will depend on the brand or type of LED bulbs.
Some are dimmable with leading edge dimmers, others by trailing edge dimmers and others don’t care.
Please check the documentation of the LED bulbs.

These are the LED bulbs I want to use:

The specs say “dimmable with a normal dimmer”, so in that case which dimmer can preferred to use with the K8006?

Sorry, after investigation, we cannot recommend any of our dimmers.
Most dimmers require a minimum load. These led bulbs are very small loads.
Even if you would put enough led bulbs in parallel to achieve the minimum load of 40W needed by most dimmers, there is still the zero cross detection issue.
As the load seen by the controller is totally different from a regular light bulb, we cannot predict how the error detection circuit will behave.
