[4ptbuck]

I just bought some URI aquasuns and these have 'built-in' reflectors.
The top half of the tubes seem to be 'shaded' vs reflected.

This got me thinking, and I was wondering what would happen if the top 1/2 of a tube was painted? Say in a silver, or a white colour. Would this not be a good thing?

Anybody have a light meter (a lux meter) and an old tube that they would be willing to experiment on?
