Fluorescent and halogen lamps may emit small amounts UVR. However, research has shown that most do not pose a risk especially if they are fitted with a diffuser or filter that absorbs the UVR. Long-term exposure to unprotected fluorescent or halogen lamps used at close distances may increase UVR exposure. Tungsten halogen lamps with incorporated reflectors are used extensively in area, display and home lighting. These lamps emit some UVR, which may be a hazard to the skin and eyes of people who remain in close proximity for long periods. In lighting applications where the lamps are close to people they should be fitted with a glass cover to block the UVR emissions
