Original summary:

Spectrum of light from a fluorescent black light with peaks labelled. The spectrum was taken with an Ocean Optics HR2000 spectrometer [1]. The spectrometer used appears to be about ~.3 to .8 nm off, judging from the location of known peaks. Fluorescent black lights are usually made the same way as regular fluorescent lamps except the clear glass used in normal fluorescent lights is replaced with "Wood's Glass", which is a glass that has been doped with nickel oxide, making it a deep blue/purple color and blocking virtually all visible light above ~400 nm. Also, the phosphor used on the inner surface of the tube differs from the typical multi phosphor blend used in normal fluorescent lights to produce visible light and in black lights is either europium doped strontium fluoroborate or europium doped strontium tetraborate to produce a peak near 370nm or a lead doped barium silicate to produce a peak near 351 nanometers. More info:[2]. Spectrum taken by me.
