2 pin vs 4 pin bulb

What are the advantages of a 4pin vs a 2pin bulb..... the manufacturer of my task light used a 2 pin bulb but the socket is made to accept a 4 pin...... Also..... the socket wire connections are of the type Leviton as seen in this photo.....

I am trying to replace the ballast.... does anyone know how to unhook the wires from this lamp holder?

Don, that photo is of the ballast, not the socket.

Some sockets have the pins crimped to the stranded wire then poked into the housing. That type is often non-removeable or requires a special tool to release the pin.

ok thanks.... if you follow the link it would bring you to the pic of the socket which was a .pdf form so I didn't know if a direct link could be done
