  • Cool factoid about this.
    I’m pretty sure this thing doesn’t emit any significant UV (black light) based on the data sheet. What’s probably happening is that the fluorescent dye in whatever it is that is glowing has a secondary absorption peak at the rated wavelength. The dye will emit the same frequency of photon when stimulated with either a UV or 450nm blue photon.
    This is a pretty common phenomenon and we just don’t notice it because we don’t usually hang out under pure wavelength light sources. (I’m a biologist and we exploit this kind of thing in all different sort of applications.)

No public wish lists :(
