Outside of the obvious (such as outdoors, in an area without 54 lux of light, and where extensive grime has accumulated on a sign face), where will Glo Brite® Ecō Exit™ Signs NOT work?
Per the NFPA, photoluminescent exit signs are not a suitable option where the illumination levels are permitted to decline and where charging source is connected to automatic timers. In areas where illumination levels need to be subdued below the minimum 5-foot candles, it may be possible to use black light for the charging source. This may need to be approved as an alternate but equal method of protection, which should only be presented to the AHJ by the architect of record or a fire protection consultant.
