Lighting for Layouts?

[RobertInOntario]

I prefer natural light from windows if possible..If not then I what I use is -well-ah hem-a floor lamp with shade since I don't like overhead lights.This works quite well for me..I use 100 watt bulbs.

I'm open to using something like this. However, I'm pleased with the bright white-ish light that my new desk lamp gives. It's a typical, run-of-the-mill large lamp that would normally be used over a desk or drafting board, etc. The light appears white because of the new 60-watt environmentally-friendly bulb. It appears quite bright and natural.

I think good lighting is important because it's quite obvious that -- if you have poor lighting -- you can easily become tired (eye fatigue). Has anyone else noticed the difference that good lighting makes?
