A sunlamp whose cylindrical envelope contains a mixture of three substances the first of which emits radiation with pronounced peaks in the red, blue and green bands of the visible range of the spectrum, the second of which emits radiation with a less pronounced peak in the long-wave portion of the UVA band, and the third of which emits with an even less pronounced peak radiation in the short-wave portion of the UVA band and down to 300 nm in the UVB band. The lamp is photobiologically effective in the UV range and is sufficiently bright in the range of visible light.
