Just like those traditional full-size fluorescent black light fixtures but in an easy to carry 5 1/2" size! Great for performances, security, and scientific use!

This 5 1/2" portable black light slips easily into a pocket and is the perfect handheld UV device. Take it onto the dancefloor and make cool effects. Use it in performances to make costumes glow. Great for security use to verify IDs, banknotes, passports, handstamps, etc. Also great for scientific use to spot minerals, urine, and more.

Uses 4 AA batteries (not included). Included lamp can be replaced with a 4W max. G5 bulb.
