I might add to my comments above are based around the disappearing incandescent bulb. Try this with a CFL bulb and all bets are off and more than likely you will get an explosion in the classic mode complete with fire and smoke. Also mercury gas I would guess.
Below is a link with some video of them exploding so you won’t have to try it to see what happens.
One thing I don’t think many people realize about the new CFL bulbs is they don’t like dimmer circuits. Some bulbs are designed to work with a dimmer but most are not. The print on the side of the package will tell you if they can be used.
