What are the advantages of a 4pin vs a 2pin bulb..... the manufacturer of my

Also..... the socket wire connections are of the type Leviton as seen in

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.
