Dr Yan 8 Posted June 1, 2011 has anyone tried this lume seems cheap and is available from uk http://cgi.ebay.ie/SALE-Acrylic-Watch-Re-L...=item4cf781d680 Share this post Link to post Share on other sites
ThinkBachs 1 Posted June 1, 2011 LumiNova® MaxLume WatchLume.... They all use the same chemical, it's a matter of which is more refined. Share this post Link to post Share on other sites

KeNnY 29 Posted June 1, 2011 Uses 30 micron Pigment - BIG ! Really the best is the 5-15 microns, for delicate watch use. It also differs from the % of Strontium aluminate and the active particles. trontium aluminate (SRA, SrAl, SrAl2O4) is a solid odorless, nonflammable, pale yellow powder, heavier than water. It is chemically and biologically inert. When activated with a suitable dopant (e.g. europium, then it is labeled SrAl2O4:Eu), it acts as a photoluminescent phosphor with long persistence of phosphorescence. Its CAS number is. Strontium aluminate is vastly superior phosphor than its predecessor, copper-activated zinc sulfide; it is about 10 times brighter, 10 times longer glowing, and 10 times more expensive than ZnS:Cu. It is frequently used in glow in the dark toys, where it displaces the cheaper but less efficient ZnS:Cu. However, the material has high hardness, causing abrasion to the machinery handling it; coating the particles with a suitable lubricant is usually used when strontium aluminate is added to plastics. Strontium aluminate phosphors produce green and aqua hues, where green gives the highest brightness and aqua the longest glow time. The excitation wavelengths for strontium aluminate range from 200 to 450 nm. The wavelength for its green formulation is 520 nm, its blue-green version emits at 505 nm, and the blue one emits at 490 nm. Colors with longer wavelengths can be obtained from the strontium aluminate as well, though for the price of some loss of brightness. The wavelengths produced depend on the internal crystal structure of the material. Slight modifications in the manufacturing process (the type of reducing atmosphere, small variations of stoichiometry of the reagents, addition of carbon or rare-earth halides) can significantly influence the emission wavelengths. Strontium aluminate phosphor is fired at about 1250 °C. Subjecting it to temperatures above 1090 °C is likely to cause loss of its phosphorescent properties. The glow intensity depends on the particle size; generally, the bigger the particles, the better the glow. Strontium aluminate based afterglow pigments are marketed under brandnames like Super-LumiNova or NoctiLumina. The best price you would have from the supplier of Strontium aluminate. But to find this supplier, you need to search hard ! I did and it brought different light to the lume powders for me :kenny: Share this post Link to post Share on other sites
seclark007 11 Posted June 1, 2011 KeNnY is strong like Ox, and smart like encyclopedia! well done, Sir! :kenny: Share this post Link to post Share on other sites
KeNnY 29 Posted June 1, 2011 KeNnY is strong like Ox, and smart like encyclopedia! well done, Sir! :kenny: Thank you but the definition (beginning from "trontium aluminate".. to .." or NoctiLumina.") is from wikipedia but hope it helps ! Share this post Link to post Share on other sites
MikeMcNair 0 Posted June 3, 2011 i absolutely LOVE "glo4u" products, comes pre mixxxd, shines like a torch, and can be ued on MANY applications....... here's a few of ther "medium" grade shit........ here is the bottle next to a Getat SUPERLUMED homage........ cotton swab near my DSSD....... the shii is BRIGHT uo!
