Of course everybody knows that high efficiency compact fluorescents do
terrible things to color perception and long time exposure (in the absence
of daylight) may cause changes in the way colors are perceived. Also, if
you have a color-sensitive activity or occupation you want to pay A LOT of
attention to this item.

To see the difference between a high efficiency and a normal fluorescent
light you'll need a spectrometer (optical, visible). You can build one
using a sliver of a CDROM and a slit. See a recipe by me in the list
archives. The difference is SIGNIFICANT and there are a number of
operations I do not want to do under high efficiency CCFL light.

I do not know if any government has the 'balls' to make everyone use CCFL
when so little data is available on long term effects.
