ᐅ LED downlight (recessed spotlight, concrete ceiling) dimmable via DALI

I originally thought it would be quite simple to find an LED recessed spotlight with about 10 watts, a wide beam angle, dimmable via DALI, and possibly a replaceable light source. I also thought it would be cost-effective if I could control a group of three fixtures with a single electronic ballast/driver.

However, reality—or maybe my limited search—has shown me that I’m on the wrong track.

Perhaps someone here has a similar wish list and can offer some advice.

Thank you!
