The reason the socket is listed as max 60 watts is to limit both the heat it gets from the bulb and the current that has to go thru the socket. So all that matters is the replacement bulb is no hotter and that it draws no more current then the incandescent bulb did. So it's safe to look at the actual watt draw of CFL and LED to make your decision. Even the brightest CFLS and LEDs for home use will draw less then 60 watts so you can use pretty much anything you want that you can screw in the socket.
