No, the very top piece of plastic with the switch unscrews sort of like the battery compartment. It's hard to tell that it comes apart there, but it does. There's an O-ring protecting it. Then you can remove two nuts from the end of the metal rods and the whole globe comes apart. You might want to mark which way the circuit board goes. Mine was keyed so it would only go one way, but I've read at least one person that managed to put it back together backwards.
