Bodine has compiled a list of often-asked questions regarding Bodine products as well as emergency lighting in general. The FAQ (frequently asked questions) section might provide the answer to your question.
Many national, state and local building codes, including the National Electrical Code® (NEC®), the National Fire Protection Association's Life Safety Code® (LSC®) and the Occupational Safety and Health Act (OSHA), require reliable and sufficient emergency illumination for commercial, industrial and institutional buildings in the United States.
In the event of a situation in which normal power is lost, stairs, aisles, corridors, ramps, escalators and passageways leading to safety must be illuminated continuously for a minimum of 90 minutes. Emergency lighting guides occupants to the nearest path of egress.
Complements original lighting designs. Commonly referred to as LED or fluorescent battery packs, Bodine emergency drivers/ballasts provide instant backup lighting when normal power fails. Each emergency driver/ballast works in conjunction with a normal driver/ballast to convert new or existing LED or fluorescent lighting fixtures into emergency lighting equipment.
Looks like normal lighting. Bodine LED and fluorescent emergency drivers/ballasts use the same light source for normal and emergency operation, complement original lighting plans and do not detract from interior design. Emergency lighting appears similar to that under normal conditions. No drastic changes in lighting or unwanted glare results.
Reduces the risk of unauthorized tampering. Bodine LED and fluorescent emergency ballasts may be installed inside, on top of or remote from the fixture. This inconspicuous positioning helps to reduce unauthorized tampering and reduces the risk of vandalism.
When installed in a luminaire, LED tube lamps (TLEDs) with integral battery backup do not create an emergency lighting luminaire. TLEDs with an integral battery backup are a user-replaceable item that is not permanently installed or fixed in place. Accordingly, they are not considered as part of the building infrastructure to be relied upon to provide illumination in an emergency situation. This type of lamp could subsequently be replaced by a standard fluorescent tube during normal facility maintenance and outside of any fire marshal regulatory oversight. This construction would be non-compliant with ANSI/UL 924 and NFPA 70 (NEC), the Standard for Safety for Emergency Lighting and Power Equipment.

Bodine emergency drivers/ballasts may be used with either a switched or unswitched fixture. If a switched fixture is used, an unswitched hot lead must be connected to the emergency ballast.
The emergency driver/ballast must be fed from the same branch circuit as the normal driver/ballast.
Bodine emergency drivers/ballasts may be installed in a variety of fixture types. They are compatible with most multi-lamp fluorescent luminaires and LED luminaires with one or more modules.
Products are available for use in indoor-dry, damp or hazardous location fixtures and, depending on emergency driver/ballast can size and application, they can be installed inside, on top of or remote from the fixture.
