Emergency lighting devices and methods are disclosed. An emergency lighting device includes a passive resonant converter circuit configured to be coupled to an emergency lighting module and to an input end of a group of solid state emitters, at which the group of solid state emitters receives a normal operation current from an LED driver. The passive resonant converter circuit is configured to receive an emergency operation current from the emergency lighting module and to provide a converted emergency operation current to the group of solid state emitters at an emergency input of the group of solid state emitters in response to the emergency operation current. The emergency lighting module may be a fluorescent emergency lighting module.
