    LED

    Incandescent

    Often used in signs, control panels, and elevators. Also known as telephone-base miniature light bulbs, these bulbs have a flat slide-in base to fit into older telephone switchboards, instruments, and indicators.
    LED—Last longer and are more efficient than incandescent bulbs.
    ET-5 and ET-6—When using bulbs in General Electric ET-5 or ET-6 sockets, match the ohms listed on the back of your socket. These bulbs do not include a resistor and are designed for use with the resistor built into the socket.
