Tom,

We have approx. twenty Gymnasiums. Vandalism / abuse is a factor. We usually replace damaged exit signs with an L.E.D.type for $59.00 which is more expensive than standard compact fluorescent type. We also consider the cost of Journeyman Electrician labor rate. The same size plastic cover is also used for emergency lighting units in Gym. We just started to use these covers in several of our Gymnasiums to see how they hold up.
