Has this sort of light source been used?
I am looking for a light source which uses a minimum of space.
Also i would like to use a light source without electrical wires, to reduce any possible influence of wires.
It would require considerable effort to fit my fibers which prompts me to ask about light placements.
Thanks in advance for insights.

I've used fiber cables for transferring quad signals from an electromagnetic deflection unit into photo detectors, but haven't tried illuminating a cell with them. I don't think they will transfer enough light (brightness) to view a typical cell. At the suggestion of another forum member, I tried EL wire (electro-luminescent) and it doesn't perform well either.
I doubt the wires connecting bright LED's would influence the magnets' field in any way. The current is less than 60mA for 21 LEDs on a LED tape (@12v). Even the most sensitive Ferrocell microscope slide would not detect such a low magnetic field from the power wiring.
I have been successful using ultra-bright T-3 LEDs. You can pack 60 into a 75mm ring. That would give you one 'ellipse' every 10 degrees.
