The National Electrical Manufacturers Association (NEMA) has published LSD 46-2009 Photoluminescent Exit Signage—Factual Review.
This new white paper, produced by NEMA’s Emergency Lighting Section, describes concerns regarding the marketing and application recommendations common to photoluminescent exit signage in the U.S. and Canada. The section seeks to educate potential users as to the drawbacks and realities of installing, retrofitting with, and relying upon this type of emergency equipment.
LSD 46 reviews potentially erroneous claims for the signage, such as those that mention “no electricity consumption,” “no maintenance,” and “exit signs illuminate for hours without charging.” Additional topics include safety, test methods for luminance levels, energy consumption, and enforceability in the field.
