How to build a nbUVB lamp

The key element of a UVB lamp is the PL-S 9W/01/2P tube. It produces narrow waveband emissions: between 305 and 315 nm with a peak at 311 nm - an effective waveband for the treatment of vitiligo.

Since the narrow band UV tube uses the same lamp caps and ballasts as general lighting lamps, we can fit the tube in a common desk-lamp and obtain the same beneficial results as we would from a dedicated UV lamp.
