I don't know. I would be curious though whether it gives off any heat
when it's 1) almost off, very dim; and 2) fully on, max bright.

If you're going to replace it, the upscale Lutron (eg. Diva model and
similar) have the advantage of being at least somewhat radio quiet;
your neighbors can listen to their AM radios even if you can't for all
stations, then. Most dimmers are tiny angry radio stations.
