Many materials sold by dealers claim to be fluorescent or have a level of shimmering fluorescence. Alas this is not always the case. Here are a few examples: Veinards Fl White Antron from Sportfish - looking bright...seems positive...  ...but no, not fluorescent  Fluoro-Fibre - my favourite tag material and something I use in the tails of nearly all shrimp flies. Here is Hot Yellow and Hot Orange (the term "hot" is often used to denote fluorescence)  Under a blacklight the hot-ness recedes...  So the orange is really hot but the yellow's not... Glo-Brite Floss - something I use a lot (Editor bodies, Executioner's red part of body, Ness C body etc etc).  Boy does it live up to its name...superb!  Eumer sell fluorescent coneheads in pink, yellow, green, orange, red, yellow and probably more. Here's some yellow, green, and red that I bought last week - all had "Fl colour" written on the pack  Under a blacklight   The very bright cone is the Fl Red which seems to be a strong orange and is the same cone that did well for me on the Don in October. The fluorescent qualities of the yellow and green was not great and very poor compared to the Fl Red. The moral of this story: get a blacklight and don't buy materials entitled "fluorescent" until they've passed the blacklight test  |

Another very interesting post, and it surprising that all materials that are marked up as being fluorescent, are not so.
I am awaiting my light, and some tests will be carried out on the materials I have. Will post the results here.

sloggi, To complete your test, take your Glo-Brite Floss off the White Spools and do the light test. You have to remember that in order for the Fluorescent to work properly it must have a White or Silver Background for the light to reflect back from. As a mirror does!

I put white floss uni glow floss white under bodies on things with mylar, lurex or braid bodies, sometimes even on trout sea trout dubbed flies
Haven't got flou light,but have a daylight type magnifying lamp,when you switch the lights of after tying the spool glows brite blue white
I also muck about with different glowbrite flosses under the mylar plastic tinsel bodies (pearl,gold,silver etc)to make subtle changes,how many people have tied pearl body on black and you get a green to black colour

You have to remember that in order for the Fluorescent to work properly it must have a White or Silver Background for the light to reflect back from. As a mirror does! AL Really? So why does the orange Fluoro-Fibre demonstrate its fluorescence so clearly against a dark brown surface? p.s. Having just done a test on Glo-Brite as you suggest, the difference is negligible. Looking at two Editors, one with a body of white non-fluorescent floss and one with fluorescent floss then the fluorescent green nylon looks to have an enhanced fluorescence but that may just be the fluorescence in the white floss. I'm not sure about the "white" theory. White shirts appear to glow under black light because they contain fluorescent compounds. This can often be traced to laundry detergent. Some everyday materials are treated with fluorescent compounds, appearing brighter than they would be otherwise. Laundry detergent is one such item. Remnants of detergent make clothing items glow under a black light hence the experience one sometimes has at a nightclub under different lighting. |

AFAI Understand it UV and Fluorescence are not the same thing don't ask me to explain as I'm not a scientist :-) A black light is supposed to pick up UV if it's a true black light, I'm not sure if it picks up all flourescent light. I think fluo is meant to be highly visible under normal light conditions (ie brighter than normal colour). Try google if your interested.

Failing the Google, your best will probably be the Wikipedia Encyclopedia where more knowledge will be gained about "Black Lights" and the "Fluoresce".  AL |
