But surely the light output from a normal fluorescent tube is not
full-spectrum, so you can't fully compensate by varying the colour
temperature? The colour spectrum emitted depends on the choice of
phosphates for the tube coating (which varies, hence "warm-white" and
"daylight" tubes and so forth) and has distinct spikes in the blue and green
parts of the spectrum.
For the idea to work, you would need to get full-spectrum tubes. Are they
made in the small sizes we would be talking about?

I've been thinking that for an E-thingy (where you can dial in the color
temperature) one of those circular fluourescent tubes would be an ideal ring
[not]flash for macro work. Anyone tried it?
