Uni Glo Yarn
Phosphorescence and fluorescence are often confused. Phosphorescent materials emit light in total darkness, often for a considerable length of time. Fluorescent materials emit light (in addition to reflecting light like ordinary materials) only in the presence of light. The phosphorescent pigment in the UNI GloYarn fiber absorbs light from any light source available (a camera flash is a favored source) and releases light or glows in darkness or very low light levels. The glow will last in excess of three hours in total darkness. Lures constructed of, or coated with, phosphorescent materials have been proven effective when night fishing for walleye or bass by North American anglers. However, fly fishers have been slow to incorporate this feature in flies. A lack of suitable materials is the likely explanation. While some Kiwi fly fishers have had considerable success catching trout at night on phosphorescent "flies," they have been forced to use impregnated plastic bodies. With the introduction of UNI GloYarn, fly tiers now have a legitimate fly-tying material with which to work. Possible uses for UNI GloYarn include trailing shucks, tails, tags, bodies, and wings, either alone or in combination with other materials such as in a blended dubbing. Unlike impregnated plastics, this new material permits tiers to control the amount of phosphorescent material in their flies.
