Security UV/black light flashlight

The listing

New battery powered black light flashlight with 68 LEDs. This is a Gearlight model XR68 light used to authenticate currency and also to detect human and animal urine. It operates from 3 AA batteries (included). I bought it at an auction and did not notice that it was black light. There are several postings online with prices varying from $9 to $16 without batteries. Still in the original box, only taken out to install the batteries.
