is there a way to convert a lighted Christmas Tree Ornament from watch batteries to plug into a mini light set???

I have a Lighted Christmas Tree Ornament that is powered by plugging it into a mini light set.  I have 5 other Lighted Christmas Tree Ornament that run on watch batteries.  Is there a way to convert these into being able to plug into a mini light set????

Shouldn't be a problem if you can get a wall wart that give 1.5 or 3 volts (the voltage of a single watch battery dependsing on the type (see battery for voltage)


Other wise you will have to make one see manufacturers data sheets for voltage regulators for details on circuits.

You may be better off running several in series from a single higher voltage wall wart or several in parallel from a constant current circuit.
