As Oreo already said, the lamp should be labelled dimmable...
For timer options with sunset en sunrise, you could go for GU10 or MR16 12 volt dimmable LED spots. And search eBay, amazon or Aliexpress for Wifi or Bluetooth LED timer controler. For example this RGBW wifi controler.

It has 4 channels even tho it says RGB and W colour doesn't matter, the output is 12 or 24 volt depending on how many volts you put in. All channels get the same output and a 12 volts or 24 volts dimmable LED spot in white colour can be connected to each channel. If you don't exceed the Max Amp rating you can put more spots per channel connected parallel.
The timer and sunrise sunset settings can be controlled via Wifi and Phone App.
I have seen a few that are able to do the same at VAC220 but these aren't really popular and not easy to find. I've personally used the
TC423 fo control VAC 220 dimmable LED lights. It's a 5 channel controller with 220 volts in and output. And needs to be controlled/SET via PC software.
âºHigh- compatibility: support 1 to 5 channel output for RGBW/RGB/dual color/single color LED lights. Output: 5 channels. â¡ CH2: It is the load output second channel negative pole;. â CH1: It is the load output first channel negative pole;.

But IMHO it contains crapy firmware same as the TC421 and I didn't like it and it can't be flashed to the older (TC420) version I liked a lot more. So I discontinued using it. But it does the job. It could be you're less spoiled than I am and this it might be what you want.
Other options depending on how much light intensity you need look at the nowadays Smart LED Bulb spotlights... These are 220VAC and can be controlled similarly to the first controller I linked to, but then need to controlled and set separately per bulb over the same App.
Could be I missed something because this stuff regarding Home Automation is developing rather fast... Maybe there are newer option out there i yet don't know about.
Search for "PWM LED timer controller" and dig through the results.
