Sunlight is the cheapest and most easily available source of ultraviolet light for phototherapy. The disadvantage of using sunlight as the source of ultraviolet light includes its variation with time , place and season, lack of privacy, and atmospheric conditions. To ensure correct dose of UV light in spite of variation in irradiation from the sunlight,we used a PMA2100 meter [Figure:2] and 2110 UVA detector ( Solar light Co, Philadelphia). Privacy for the patients was achieved by erecting a solarium and incidental UVB radiation was cut off by using window glass as the roof of the solarium. We recommend the solarium as a less expensive alternative to artificial phototherapy units, especially in places where there is plenty of sunlight.
