To determine what light and wavelength you want review the application. Invisible Inks come in many colors. All Clear Blues can be seen with any of our UV Lights. The Clear Reds and Clear Yellow Invisible UV Inks require closer to 365 nm. So if you are using the MAR-C0 Invisible Blue Pen you can use any of the lights. The stronger the black light the brighter and farther you can see the invisible ink. Also the darker it is, the more you control the ambient light, the better the response.
