How many of us- including me have table lamps which have the shade clipping around the bulb???
Those shades don’t fit the CFL bulbs. So-—either more American jobs lost here or more shades being made in China or both.
Some of us get headaches with the CFL bulbs. I am one.
I not only get headaches, words blur when I try to read by their light. With flourescent lights, I can't always discern subtle differences in color.
To read, I depend on 100-watt light bulbs or natural light. I found that time in modern classrooms with flourescent lights, a lot of technology for reading and no natural lights affect my concentration and reading comprehension.
I can't help but think that it's a not-uncommon problem, and a lot of learning and behavioral issues are caused by that artificial environment for vision.
