Emergency ballasts and drivers keep light fixtures lit if the main power goes out so people in the surrounding area can see where they're going as they evacuate. These products help building owners meet code requirements for emergency lighting without having to install separate emergency lighting fixtures. Emergency ballasts and drivers install inside light fixtures to provide backup power to the fixtures in an emergency. Emergency inverters install outside light fixtures. They can provide backup power to multiple light fixtures and are compatible with most types of fixtures, including fixtures that do not use ballasts or drivers to power their light bulbs. Emergency lighting devices for generator systems transfer lighting fixtures to backup generators or central inverter systems that kick in to supply power to large facilities during power outages.
