[QUOTE="doctorjj, post: 1292290, member: 7292"] The flickering associated with older linear style fluorescent lights, which did flicker between 60-100 Hz, could be associated with triggering epileptic seizures and migraines. Modern CFL's "flicker" at a rate of 60,000 Hz and modern linear fluorescents flicker at a rate of 50,000 Hz. Both of those flicker rates are well above what the eyes or nervous system can detect. If you get migraines under CFL's, it's much more likely due to glare, contrast, or improper lighting and lighting design, all of which are proven to be migraine triggers, rather than a phenomenon of the "flicker" associated with the bulb design. BB, As for your anecdotal report of CFl's triggering your migraines, my advice would be for you not to expose yourself to CFL's. However, that being said, without a double blinded study there is no way to rule out other causes for your migraine trigger. I think I fit into most of bettingpython's categories. LOL!!! [/QUOTE]
