Advice required re LED's.

I find led light tiring.
I would use halogen lighting as its colour is like daylight.

This is useful information.

I learn I need as full a spectrum as possible, tired eyes I do not
want.

You don't get full spectrum with white LEDs. They are basically blue
LEDs with a fluorescent material to produce the white light. There are
lots of holes in the output spectrum.

Also it is unlikely you will get sufficient brightness. You'd need a
shed load of LEDs to rival the brightness of a 50W halogen.

I'd stick with your halogen lamp. You can get LV bulbs with built in
dichroic filters if you are concerned about the colour.
