Hi All,
I tried the following three time each way:

1. I placed a clear "ceiling fan bulb" in a 4" diameter 2" deep clear 
glass dish of water. Microwaved on high for 15 sec. Got beautiful 
orange and green glow inside along with white incandescence of filament.
2. I floated the bulb base down in a 2" diameter , 4" high clear 
glass cylinder of water.  Microwaved on high for 15 sec. There was no 
lighting of the filament nor was there any glow of the gas.
 In attempting a fourth trial #1, the filament support 
melted/vaporized and test continued without producing any light/glow.

I placed the burned out bulb on the carousel Microwaved on high for 
15 sec and It flashed several times. White filament, orange and green 
glows, and several streamers noted.

I don't know the details of your experiment but I would expect if the bowl
of water is large the light bulb will not light if its just placed some were
else in the oven as the water absorbs too much of the energy.

In my experiments I was in the habit of putting a half full mug of water in
the corner of the MO so there was always some load.

In order to hold the light bulb upright, on one occasion, I put the bulb cap
down in the mug and put the mug in the center of the MO.
The bulb appeared to light immediately and very brightly. I assumed the
water was grounding (or adding a ground plain to) the connections to the
filaments and hence it was better matched to absorb the energy. i.e. it was
a better monopole. In this configuration one bulb got so hot the envelope
expanded  like a balloon then suddenly exploded much to the amazement and
surprise of my audience. I have tried it a few times since but never been
able to reproduce the balloon effect. I don't know what the gas pressure
inside modern light bulbs is but I would assume its too low to ever get
greater than one atmosphere even with heating.. Perhaps it had a slow leak
and was actually at atmospheric pressure initially and that's why I have
never been able to reproduce the effect.

Perhaps a similar effect grounding effect with your floating light bulb.
