If the sun lamp is the sort that can cause a sunburn, it has the wavelengths of light required to make vitamin D. UV-A is the tanning range of wavelengths. UV-B is the burning range of wavelenghths, but also the one that creates vitamin D. The distinction between UV-A and UV-B is arbitrary, but that's the rough picture.
