Frank,

I guess since they're lit so nice, an exit sign does make an irresistable target for a basketball.

Your use of LED type exit signs is the right choice. When I show my customers the savings in power company charges, they are convinced. After all, they're a 24/7 load & even a small load adds up. The old incandescent ones will probably become museum pieces pretty soon.

Few things are harder to put up with than the annoyance of a good example.
