Experimenters with Microwave Oven

The probe bulb is flashing very brightly according to Oven's magnetron pulse radiation. I experimented with filament bulb for 120V/40W, 120V/60W and 120V/100W. All bulbs flashing enough brightly in depend of a load (water, meals, etc) that was being inside of the Oven.

Next step was to test a CFL lamp. I have lots CFL lamp with removed base (I used the base to find electronics parts for my experiments). Figure 4 shows the CFL lamp with removed base. I put the CFL lamp inside of the Microwave Oven with some meals and turn on the Oven. The CFL lamp is flashing steady very brightly do not depend on to oven's magnetron pulse.

It was understandable for me. CFL lamp makes light because of luminophor on the inner side of tube. The luminophor has low reaction - turn off any CFL lamp and see that it was not be dark immediately. At usual conditions the CFL lamp is lighting because of low temperature plasm inside of the lamp. The plasm generate UV that luminophor transform into visible light. In normal working conditions the plasm occurs due to high voltage across the CFL bulb leads. In the Microwave Oven the plasm occurs due microwave radiation. I tested in the Microwave Oven working CFL with working base. It is not damaged the lamp.
