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...
