Barb, the effect of the fan under the flouresent light, is a strobe effect, if you pulsate a light source at the exact speed or multiples of the speed of a moving object, such as the fan blade, the object appears to stop. This is used to examine a part for defects when under operating conditions. It can also cause discomfort when the speed varies, and the reflection of light from the object is seen by the eye. I wonder if these effects can be used in a positive way to help PWP??? I do know that a light source powered from household frequencies could be run from a DC, that is a direct current, source, and the resulting light would be steady, like daylight. I hope this discussion can be of some use to the cause. [OO] LOOKING FOR RADIOS! Ken Becker [log in to unmask] On Tue, 8 Oct 1996, Barbara Mallut wrote: > Ken....
