Glow in the Dark Signage is a great way to save on electricity and conform with building security codes.

This also creates an awesome effect at night.  Glow in the dark ADA signage can help if there is a power outage, which we have

been seeing alot of this past year with hurrincanes, earthquakes, and massive snow storms.  Also use in your skylight casing

to light up your hallways at night.
