The latest LED lamps used in non-destructive testing are safer and easier to handle. Ultraviolet radiation is used in fluorescent penetrant and magnetic particle nondestructive evaluation methods to fluoresce materials used to indicate the presence of flaws in safety critical components, This is especially the case for components used in the aviation, space, and automotive sector. The specific radiation that is used in these tests is governed by ASTM E3022 and Rolls Royce 90061 and has a wavelength of 365nm + or - 5nm. This specific ultraviolet radiation wavelength allows operators to work safely while performing inspection using standard personal protection equipment. The process of creating Ultraviolet (UV-A) radiation has evolved over the years and today the use of instant-on LED technology is prevalent in industry, Operator efficiency, operator safety, and environmental safety are maximized using LED UV-A technology. The use of LED UV-A lamps implements a number of safety advantages compared to other methods, such as low temperature housings, low voltage circuit design, lightweight design and the elimination of the use of mercury.
