I suppose you could fiddle with it a bit, and remove the shutdown 
mechanism, or take out the essential parts and put them in a new case (or 
have them sit in the open).  Might work, if they are built in a way that 
you could take out the driver circuits and transformers to get the power 
without other little safety circuits.
