Emergency Lighting Kit For Fluorescent Lamp

Lighting emergency power supply kits from the Vip st series are
designed to be encased in lighting fittings equipped with 4-pin
fluorescent light sources with power ranging 4–58 w. In case
of power failure, these kits automatically switch light source
into that supplied from batteries, and continue operation with
reduced luminous flux for the nominal time of 1–3 hours (model
dependent).
