Ideal for a range of applications from art projects to security checks, it dries quickly and adheres well to various surfaces, making it a must-have for creative professionals. ## Description Use all-purpose, semi-permanent Glow Authority's Illusion Invisible Blue Ink for security checks, art projects, scavenger hunts and secret visuals.The result will largely vary, depending on the surface and the light source. Please use as directed.LED flashlights are recommended for security checks, scavenger hunts and secret visuals.LED fixtures are great to fill a room. LED bars (from 18" to 48") are typically between 27 to 50 watts, whereas LED squares are around 50 watts. LED fixtures are recommended since they are cheaper, efficient, harder to break, and require less energy.Neon/fluorescent tubes are intended for professional use. They provide a richer experience and allow each UV-reactive color (not just our ink) to activate.Avoid any lightbulbs you can screw in such as e26, e27, GU10, etc. Also avoid "dollar store" light bulbs and UVC shapes. These lightbulbs tend to offer poor performance and the ink won't react. ## Features - [UV REACTIVE] Invisible in normal daylight but dazzling under ultra-violet (black light) light source. - [MULTI PURPOSE] Perfect for security checks, art projects, scavenger hunts and secret visuals.
