Abstract
Abstract A removable power pad is disclosed for use in supporting critical power components of a luminaire such as ballasts and capacitors. Plug and socket connectors are used to complete connections between the power pad and the power supply. A safety lock is provided to hold the power pad in place in the luminaire so that it will not fall out prematurely and injure a workman after a primary latch is released.
