Extended Runtime Products
While 90 minutes is the standard code-required time for emergency lighting operation, there are cases in which more than a 90-minute runtime is required or desired. For example, a hospital, school or assisted living facility might benefit from a longer emergency lighting runtime. Philips Emergency Lighting offers emergency ballasts with two- and four-hour runtimes to accommodate special applications.
Extended runtime emergency ballasts are compatible with electronic, standard, energy-saving and dimming AC ballasts. These models are UL Listed for factory or field installation.
