The beam has a fairly narrow focus and unlike a traditional blacklight, most of the light produced by the UV Photon is just outside the visible spectrum (370 nm). In full darkness it will cause objects to fluoresce at distances of 20 feet or more. In bright daylight the effectiveness is greatly reduced, but is still usable at about 6-12 inches.
