Double ultraviolet lamp L 81, long/short wave
Article number: 325178
This practical UV hand lamp combines two functions in one device. Stamps, banknotes, credit cards, phone cards, etc. can be tested for fluorescence and phosphorescence in equal measure. The combination of short-wave and long-wave UV rays (254 / 380 nm) makes the lamp extremely practical for the user. The UV flashlight has a built-in filter against long-wave residual light*. Battery works: 4x AA. 4 watts (254 nm) or 3-4 milliwatts (380 nm). External format: 55 x 163 x 23 mm.
*Short-wave UV lamps have a residual amount of long-wave UV light, which can make analysis difficult. The double UV lamp L 81 contains a special filter in front of the short-wave lamp that filters out this long-wave residual light.
