   Look nice - but this app is 120vac all the way.

   Alas all the little ones are rated for 40w max, which
   is fine if you stick to LED bulbs, but SOMEBODY might
   stick a filament bulb in there someday.

   About the physically smallest I came upon early is a
   RAB Lighting SMS500W ... but it still uses a 1/2" hole
   and would hang out under the light unit. We'll see.
