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-395 lamps provide an LED-generated ultraviolet light output in the 395 nanometer range. These can be used for fluorescence applications, curing, or sample-irradiation. 395nm is a popular wavelength for curing applications.
