Sylvania makes fluorescent lights that screw into bulb sockets. They work fine
with 100v power.

See previous message.

Excellent pointer! Thanks Amara.

LEDs would work well in an RV or some other application where you have
low-level DC, otherwise forget it because you'd need to install power supplies
to convert AC to DC, which would more than offset any savings in energy. I've
noticed, however, that the city of Redding, California has been replacing
traffic signals with LED units.

Good idea. Sadly, my local utility offers no rebates. Happily, we don't have
rolling blackouts here.

Yes, this prevents losing some of the cold air stored in the refrigerator when
the door is opened.. Also, frozen water in the freezer can be moved to the
fridge in case of power outage, preventing food spoilage.

Stay hungry (thus opening fridge door less often),
