Portable 4W 365nm UV Light Lamp Detect Fluorescence Stamps Philatelic Tagging Description: This model detects fluorescence in the longwave, broad spectrum of U.V. Light for stamps, and tagging on currency or phone cards. For assured phosphorescence detection of all modern Canadian stamps Also suitable for the stamps of Mexico, Norway, France, Portugal, Hong Kong, China, Russia and definitives of Great Britain after 1992. Long wave UV light tube included Peak radiation efficiency at 365 nm Hand held portable model. Requires 4 AA batteries (not included) Reliable detection of luminescence Note: Please also note that the lamp will NOT work with rocks and minerals either! Longwave lights have their place in detection of fluorescence in rocks and minerals but the first time buyer must be aware that only a small percentage of fluorescent minerals will react to longwave (LW). The bright, multi-colored specimens you see in the Nature’s Rainbows photo gallery almost always require a good SW light (with filter). if you don’t see a filter on the light (a dark glass allowing only a purple/violet light to escape), don’t waste your time. UV lights generate a lot of visible light in addition to the UV. This light must be filtered by UV pass, visible blocking filters. These filters are the most expensive part of the unit and are essential for detecting fluorescence! The lamp being offered is perfect for Canadian stamp collectors but don’t even think about it for rocks and minerals! Package: 1pc 365nm black light torch
