According to this article energy saving light bulbs could trigger migraines and even seizures in some people. The Migraine Action Association has said that the flickering and the low intensity of the light do trigger migraines in many of their members. There have also been warnings from epilepsy charities about the increased risk of seizures from energy saving bulbs. With the government pledging to prevent the sale of the conventional light bulbs within the next four years this could be worrying for sufferers of both conditions. As a migraine sufferer myself I have replaced most of the bulbs in my house with energy saving bulbs and so far have suffered no migraines. However, it might be prudent for the government to research this issue further before going ahead with an outright ban.
