When Ultra Violet light is mentioned most people immediately think of sunbeds, counterfeit money detectors,scorpions,CSI,insect traps or fish pond sterilization units. However, ultra violet light is all around us, not just occurring naturally from sunlight but manufactured commercially by companies such as UV Light Technology Limited which, through high-tech industrial, commercial, public services and medical applications, make our daily lives more comfortable, secure, healthier and fun!

From treating vitamin D deficiencies and relieving the unsightly effects of Psoriasis, UV-A and UV-B light is used in many treatments and research projects in the world of medicine. Latest medical breakthroughs include fluorescent dyes used in conjunction with blacklight to identify cancerous cells in the internal organs of patients.

In the worlds of science and engineering it is so often vital to establish the aging effects of the sun on materials for safety and aesthetic reasons. Ultra violet light sources which closely correlate to natural sunlight are used in a vast range of applications from testing aircraft windscreens to examining the effects of degradation on building materials.

UV blacklight fluorescent inspection processes make working life easier for quality control engineers, forensic scientists, fire officers and auction houses to name but a few. Under UV blacklight hairline cracks can be detected in aircraft undercarriages, automotive steering systems and many other critical components upon which our lives may depend. In the field of forensics UV blacklight helps unearth vital evidence at crime scenes and plays an important role in identifying the cause of fires. The inspection of works of art under UV blacklight is a means of revealing imperfections and evidences of restoration, an important aspect of authentication for valuation and sale.

The special effects industry has embraced ultra violet blacklight for its ability to produce stunning visual effects as if by magic. Festival tented environments use UV responsive drapes, pop concerts use multi image 'trompe l'oeil' backdrops illuminated by UV and in night clubs UV is what makes your white clothes glow in the dark.

Ultraviolet light, or "black light", reveals changes in elemental composition on the surface of objects because it causes specific fluorescence in materials depending on composition and age. Retouching, overpainting, varnishes, adhesives, and certain types of deterioration that might be invisible to the naked eye, like mold damage, can be detected and identified. UV fluorescence can sometimes make erased ink visible, can indicate overpainting or retouching, and can help identify different types of stains. For example, oil stains fluoresce orange, wax or starch can be bluish, or unsized paper deep purple. Different types of mold stains fluoresce differently, so even the kind of mold attack might be identified. Often mold attack is apparent in UV fluorescence even when it is completely invisible in normal light.

Microbiologists are employing UV-C germicidal lamps within engineering control measures to reduce infection caused by airborne transmission of bacterial pathogens within built environments. Furthermore, some of the water we drink has been sterilised using UV-C light, as has a wide variety of food, drink and medical supplies packaging. The blacklight is used for finding urine stains, scorpion hunting,antiques collecting, pest control people use it for rodent inspecting, and used at readmission gates in concerts, casinos, clubs, etc.

Application of fluorescence and phosphorescence for special effects Fluorescent materials, whilst brighter than most materials under normal light, will glow only when illuminated with ultra violet (UVA) blacklight. Phosphorescent materials will "charge up" under normal visible light and emit light in darkness. These may also be charged using ultra violet light, for brighter and often longer periods of light emission. As with fluorescent materials the phosphorescent equivalents will glow under exposure to ultra violet light, but phosphors continue to glow when the UV light source is removed.

Summing up everything, a blacklight would be a good choice as having in one’s possession in this era. From the ability to locate a tick on one’s body to identifying scorpions, to fakes and repairs in art, glass, china, pottery and locating fingerprints, semen, etc at crime scenes. Who knows what the blacklight might reveal in the latest biological warfare attacks now being thrust upon the public such as uv to identify stink bugs. One can see the importance of ownership.
