  4. Electrical ballast - Wikipedia

    en.wikipedia.org/wiki/Electrical_ballast

    It can be incorporated into an existing fluorescent light fixture or mounted remotely outside of it. When power is lost, the ballast will illuminate one or more lamps in the fixture at a reduced output for a minimum of 90 minutes (as required by code). These can be used as an alternative to egress lighting powered by a back-up electrical generator.

    Numeric code Alphabetic Code Fluorescent lamp type Notes 05 N/A Germicidal lamps: No phosphors used in these lamps at all, and the enveplope is made of fused quartz instead of glass. In the American lamp code, the F as in FxxTyy is replaced by a G as in GxxTyy, indicating that it's a germicidal lamp. 08 BLB Black-Light Blue lamps

    This lamp replaces the opaque ceramic waveguide in earlier lamps with an optically clear quartz waveguide that increases efficiency. In previous lamps, the burner, or bulb, was very efficient—but the opaque ceramic waveguide severely obstructed the projection of light. A quartz waveguide passes all the light from the plasma.
