Of course it's always better to err on the side of safety, but as I
understand the operation of Black Light fluorescent bulbs, they may emit a
certain amount of light below the visible spectrum, but still, we see
light when the bulbs are on. In other words, if light escapes from your
light table, it might include wavelengths not visible to us, but we would
still see light, hence know UV was nigh.
