I think CFL's are the worst (so I am told, by a friend that does suffer of migraines), leds in a warm range 2700-3000K should be fine in most cases. If the migraine is triggered by flickering, there are "special" flicker free bulbs, dimmers and power supplies/drivers (actually I think they make the flickering at a very high frequency, 1250 Hz or more instad of the "normal" 100-120 Hz). I read that there are glasses with special lenses that may help, but of course it depends on the specific case, I know that there also filters (to be applied to lighting fixtures) but I have not any experience with them.
