I want to tell everyone what a huge difference full spectrum lighting
can make. I bought one from Ebay recently and ever since my room has
been filled with a wonderful white glow. It's economically and
ecologically friendly as well, taking only 30 watts to produce as much
light as a 150W incandescent bulb would. And it lasts 8000 hours
compared to the normal 1000 hours.

Has anyone else tried full spec lights?

If you haven't, I totally recommend trying it. Not only does it
improve your mood and health, but cuts down the electric bill. If you
buy one, make sure it says 'CRI>95' and that the temperature colour is
6000 minimum (anything under and you won't get the proper 'white'
feeling), and one that has a luminosity of at least 1200 lumens.

The white glow it pervades is instantaneously relaxing. Walking from a
room with normal yellow lighting into that - the difference is just
remarkable. It's also a good favourable condition to work with the eye
charts in, because it renders the blacks in a truly vivid black that
you can't get with normal bulbs.

They are also ideal for gazing directly at (the stronger the better).

If you are living in the UK, just ask and I can tell you some good
links for where to get them.
