Does the ink in the edding 8280 Securitas UV marker glow even if the UV lamp is 1-3 metres away? Is the ink fluorescent?
No, unfortunately this does not work, from a distance of 1-3 meters the light beam of a UV lamp will not be sufficient to make the markings glow, here we rather assume 30-50 cm. The ink is not fluorescent and is only visible when the UV light shines on it.
