If K0RF has the older technology fluorescent some people are sensitive to the
120 Hz flickering of the lamps. Plus the phosphor technology in the older stuff
was not very good creating accurate colors. The combination could cause eye
strain and as you stated is very tiring.
The new technology drives the lamps at 25 kHz or higher and the phosphor
coatings in the new lamps result in fairly accurate colors.
An added benefit to switch to the new technology is it uses about 1/2 the
energy for the same light output.

Guys,
Interesting about the lighting. K0RF has these typical in-ceiling
overhead fluorescents in his radio room. Those things fatigue my eyes and put
me
to sleep! So, when I single-op at Chuck's, I bring a long-necked,
adjustable high-intensity desk-lamp--focused on the work at hand--and turn
those
fluorescent-things off. Every time he walks in the room, though, he turns
them on...so, we have the "Battle of the Lights!" I bring the high-intensity
lamp for our multiops, too, and it does seem to ameliorate the
fatigue-effect of the overheads--which are always on for those efforts. Not
sure what
it is about overhead fluorescent lighting that affects me--but I know it's
true. Guess I need to research the color spectrum-thing, too...
