The National Electrical Manufacturers Association has published EM 1 “Exit Sign Visibility Testing Requirements for Safety and Energy Efficiency”, published by NEMA’s Emergency Lighting Section.

EM 1 establishes a high-performance category for internally illuminated
exit signs that goes beyond former Energy Star requirements and existing
CSA and UL standards for those products. This standard forms the basis
of the emerging NEMA Premium Exit Sign program. The program, like the
standard, will be based on performance, rather than simply energy
efficiency.

“Exit signs are one of many lighting installations facility managers can
look to in the quest to reduce energy costs, so long as changes do not
come at the expense of life safety,” said Eric Bailey of Philips
Lighting, chair of the Emergency Lighting Section. “EM 1-2010 provides
the visibility and energy-efficiency requirements that signs must meet
to qualify as NEMA Premium products. By focusing on visual performance,
this program goes beyond energy efficiency, and will recognize the
highest performing exit sign products on the market.”
