UV torch 3W

Summary

The most powerful for its size, fits easily into a pocket (it even has a clip, keep it in your top pocket). If you work at fairs and markets, centres and galleries, this is the one to keep with you at all times.  Really serious dealers should keep one of these in their pocket and a large (even more powerful) one in the shop. 

Takes one AA battery.

- it is still 'lit' for another 1 hour but too dim to be of use
