LED/UV Solar keychain flashlight

Item No. DK18701

Finish: Purple, black, yellow or red

A solar powered flash light keychain with UV light source to observe the fluorescence in diamonds for the purpose of colour-grading. The LED light source offers a convenient bright light for many uses and when left for a short time in the daylight recharges quickly. The UV light can be used for observing the fluorescence (glow) in UV security marks, which are otherwise invisible. These can be found in banknotes, cheques, cheque cards and anything marked with a UV security marker. UV light is also widely used to detect modern surface paint on antique porcelain or paintings, signatures added to drawings and paintings, and writing on letters and postcards that are too feint to see in natural light. This item makes a useful tool for staff and a great promotional gift for your customers, available in the shown colours and can be engraved or printed subject to an MOQ.
