UV torch 5W + 18650 battery + charger

Summary The most powerful of our standard UV lights (there is a specialist light which is 15W). If you want one that is the most powerful without going over-the-top, this is my recommendation.  Takes one rechargeable battery (battery and charger included).  Read all about how UV light works and what it will detect (fascinating article!)
