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.

There exist 'warm white' LEDs, which don't do this.

really, what manufacturer?

I thought that LEDs by their nature only produce a narrow spectrum of
light.
