And yes, fluorescents are the way to go, but only if they have been
amade. One popular brand has a short lifetime and as a result is not
"flickerbargain according to Consumer Reports.
One other thing to consider - there are many of us whose visual
fusion frequency" is significantly higher than average. Fluorescentlights
that most people see as glowing steadily are constantly oscillating inlocal
brightness in our peripheral vision. Going to a grocery store or the
Wal-Mart is sheer torture. I have removed the fluorescent light bulbsin
myof
office and use only incandescent lighting. I teach my classes with the
shades fully up to let in maximum sunlight. I leave only the last row
fluorescents on in the room. Students who really want the excesslighting
can sit there. Surprisingly, the students adapt very quickly to theuse of
predominantly natural lighting - they now protest if someone walksinto
the
room and turns on the lights. We use whiteboards and markers, students
have
no problem seeing the class material.
