Somehow used bulbs, in they work then this is a bargain, but if they dont... Well worth trying. We will not guarantee operatin (we have not a single device where to test them)

Why to use ultraviolet light?

In today's society, tailor-made UV radiation is state of the art technology. It sterilizes Water and surfaces, hardens paints, adhesives and plastics, exposes printing plates and helps recognize forgeries, decayed foods and hairline cracks in work pieces. Last, but not least, UV radiation can be used very effectively for advertising purposes and for special effect illumination in theaters, discos and bars.

So about the myths:

This lamp is sold without any warranty, since we have no equipment to test the lamps. Also we reserve right to be mistaken about the "myth" part of the specifications.
