Remember for these lamps to be effective, you must position yourself and the artwork in a totally dark environment. Avoid an enclosure with noticeable light leakage, as it will interfere with the effectiveness of the lamp. Also, do not look directly into the light, as it can harm your vision. Instead point the lamp at the artwork.
UV refers to ultraviolet. It is sometimes called black light because it appears quite dark even when lit. Recently applied paint or graphite or ink, etc. absorbs ultraviolet light and therefore appears dark, allowing for the detection of newly added pigments (inpainting).
