some electronics dry out and are fine... others not. A flourescent fixture to me would not be ok because of the ignition in the balast. I have however seen cell phones dropped in pools and live a happy life after drying out. I would attempt to try it, off the tank of course, after time... but thats just me. Im pretty sure on the other hand that canopies for 10 gallon are fairly cheap. When you do plug it back in after drying out, plug it into a GFCI with the fault button on the outlet, probably in your bathroom or kitchen. If it shorts, it will pop that breaker rather than zapping you.
