Visual examination plays a major role in deciding the right treatment. This demands a high level of general illumination as well as good colour rendering to show the true tone of the skin. Since patients do not stay in an examination room for long, ceiling mounted luminaires are the best way of reaching the 500 lux average requirement. The high colour rendering requirement of Ra 90 means careful selection of lamps is necessary.

An arm based examination lamp mounted on a wall, ceiling or trolley is the ideal supplement to the general light for examinations and treatment. These provide excellent colour rendering and a focused beam. Depending on exact requirements either a multi lamp unit or single lamp head can be chosen, but the important thing is arm balance and movement, so the light can be directed exactly where required.
