I would expect so if the diode output varies instantaneously with applied voltage,especially if half-wave rectification is used.

The problem seems to stem from the fact that incandescents filaments thermal mass moderates the light output to something very close ly approximating a steady glow.Connecting an oscilloscope to a photocell will reveal a residual 50 or 60 cycle variation in the output of incandescent but will show a fluorescent as being more like 100 or 120 flashes per second.The brain has to average out the bright flashes which accounts for the headaches.

It has been proven that having your computer or tv scanning the picture at 50 or 60 Hz is more tiring to the eyes and brain ;having such a computer screen in a standard fluorescent lit area adds to the problem.

I believe our bodies and brains were designed for an analog world and all these sampling methods which make the brain fill in the gaps,whether of light or music, cause un-needed stress.

I know my mother has always claimed that flourescent lighting was a strong contributer to her needed to wear glasses. When she went to school and graduated in 1956, the schools used incandescent lighting then but when she went into the working world, even then, it was mostly flourescent lighting. By the time she was 21, she needed glasses. I know myself, I'm very near sighted, I got glasses in third grade, I often wonder if flourescent lighting is a contributor, my school had those lights, it was the early to mid 1970's. I know in one of my experiments in my Radio Shack 150 in 1 Science Fair kit, you can hook a solar cell up to an audio amplifier and you can "listen" to various light sources, the sun has a nice "hiss" to it, regularl ight bulbs have a similar hiss but flourescent lights have a hideous buzz from the 60 cycle power.

BTW, I'm an amateur radio operator too.
