In some instances, the wires can be soldered directly to the device and is indeed commonly done within the SSL assemblies. Tyco Electronics recently released the SMT Poke-In connector that provides a poke-in L3 termination to a printed circuit board thereby eliminating the need to solder the wire to the board. In other instances, it can also be the interconnection between circuit board assemblies as can be seen with the Hermaphroditic Board–to– Board connector used for SSL strip lighting. On the traditional lighting side, an L3 termination is typically just an FASTON, screw terminal, or poke-in terminal on the side or base of an Edison socket or fluorescent tombstone.

With an LED lamp, this would be the connection to the LED driver. For fluorescent lamps, this is the connection to the ballast. In both instances, this can be a separable plug and receptacle connector, a poke-in 14
