The fluorescent devices produce a more intense light and can aggravate a range of existing problems, especially in those with light-sensitive conditions. There have been growing concerns that low-energy light can trigger migraines, as well as dizziness, loss of focus and discomfort among those with epilepsy. There have also been complaints from sufferers of lupus - an auto-immune disease causing many symptoms including pain. The latest warning was issued by Spectrum - an alliance of charities working with people with light sensitive conditions - and the British Association of Dermatologists (BAD). Critics complain low-energy lights are either "cold" or "green," take up to a minute to warm up properly and because they are fluorescent, flicker. |
