See Every Detail with Dual UV Lamp
Switch from Longwave to Shortwave with a Push of a Button
Precision UV lamp makes it a breeze to see even the finest details on stamps, banknotes, telephones, credit cards and more.  And as you know, the slightest difference can have a huge impact on value.  With this versatile lamp you’ll enjoy your collection more – and avoid making costly errors in stamp identification. Experienced collectors use ultraviolet (UV) light to detect details invisible to the naked eye.  Many U.S. stamps have features that help automate mail – “taggant” of phosphorescent or fluorescent material that’s “read” by an optical sensor.  Phosphorescent tagging can be seen under shortwave UV, while fluorescent tagging glows under longwave UV.  Shortwave UV light can also be used to detect different kinds of paper and repairs such as reperforations and filled-in places.  This “dual-wave” lamp produces both forms. And the dual-wave lamp is easy to use – with one push of a button, you’ll switch between 254 and 380 nm.  Plus its compact “slimline” design and carrying strap makes it convenient for stamp shows and club meetings.  Operates on four AA batteries, not included.
