Summary: Reduces Strain On Eyes
Comment: 3M Polarizing Light Lamps do exactly what they say, reduce strain on your eyes. Normal light is what is called 'unpolarized', that is, light waves are erratic and the eye has to strain to see them. 3M's lamps polarize the light, filtering out waves not of a certain orientation. Indeed, having this lamp for about 1-2 years, I find the lamp still gives out a strong light, without the strain on the eyes you would associate with this lamp.
Try it, you won't regret it. The only gripe I have is that the tightener to hold the lamp in place has slackened a little, requiring some propping up to get the angle of light I desire, but other than that, its been a good servant to me.
Black is also a nice colour.
