This is a 6 Watt illuminator module with two highly-flexible LED gooseneck lamps. The 22" lamps can be bent in any direction allowing for complex lighting scenarios. With the voltage-attenuation slider, the light-intensity can be adjusted for various needs. The UV-365 lamps provide an LED-generated long-wave ultraviolet light output in the 365 nanometer range. These can be used for fluorescence applications, curing, or sample-irradiation. 365nm is commonly used to test for fluorescent dyes, such as those used in passports and bank-notes, and for grading diamonds.
