Description:

This is a low energy compact fluorescents lamp. It has special internal coating to produce deep purple light and large amounts of UV light. The purple glow of a black light is not the UV light itself, which is invisible, but visible light which escapes being filtered out by the filter material in the glass envelope.

These bulbs emit UVA, the long-wave type ultraviolet light, and are intended for use in special situations. This can be simply for lighting effects, such as in discos, theatres, clubs etc. The invisible UV light is reflected back in the visible spectrum by fluorescent materials and dyes e.g. white clothes glow brightly in the dark, fluorescent posters illuminate, fluorescent paints light up. Also useful for curing applications of pigments, inks, adhesives, varnishes, coatings and gels.

Other uses of uv light is in authentication, e.g. markings on & credit cards, certificates of authenticity on packaging, as well as special inks used by marking pens; non-destructive testing of materials and reading of otherwise illegible papyri and ancient manuscripts; analysing minerals and gems, and other detective work including authentication of various collectibles - materials may look the same under visible light, but fluoresce to different degrees under ultraviolet light.

UV light can be used for illumination of subjects of photography, as many plants, , fruits, and especially flowers appear different, as they would to some insects, birds, and reptiles that can see near-ultraviolet light. Entomologist use UV light for attracting and collecting insects.
