There are several US dimmers rated for 600W Incadescent/Halogen loads - Leviton, Jasco, Inovelli, Lutron Caseta(not zigbee) that I know of, probably others.
Make sure you are looking at full specs, generally they are rated separately for LED vs Incadescent/Halogen. The above examples are 100w-150w for LEDs.
I would have thought at 220V ratings would actually be higher.
