24 Volt Chrismas light string

There are also battery-powered strings available that use AA-size batteries if you didn't want to go the DIY route or do the inverter thing - I think Hobby Lobby has them.

Thanks for all the usefull advice, I "batteryed up" for this year, found several useful 24v power inverters that will be on time for future operations.
