Black lights produce ultraviolet light (UVA), a type of electromagnetic radiation, which human eyes cannot see. What we see under a black light is phosphor, a common ingredient in laundry detergent. It turns the invisible UV light into a visible white glow. White socks and t-shirts work well, check that your detergent is not phosphate free though. Teeth, finger nails, glow in the dark products, fluorescent highlighter will also glow brightly as well as some paints and plastics.
Includes one black light compact fluorescent light bulb with bayonet fitting 15W 240V. This light bulb is non dimmable.
Recommended for 10 years and over. Not suitable for children under three years of age.
Package size: 175 x 42 x 42mm
