The EMF Lantern detects EMF and illuminates up to 5 colors. The bottom row illuminates a low intensity blue when turned on. When a slight EMF is detected the blue light changes to bright green. As the intensity of the EMF increases the colors light up each row of yellow, orange and red. The EMF Lantern is silent, great for quiet settings.
