A medical light therapy lamp is a source of light which has an intensity of 2500 lux. Halogen lights are not to be used for light therapy. Medically certified therapy lamps have the necessay criteria for light therapy treatment. The light must be continuous (not flicker).
An opaque protective screen which filtres ultra violet rays covers the surface of the light therapy lamp. The intensity is adjusted so that there is as little dazzling to the eyes as possible from the lamp.
