INON Underwater Light

As you can see, there are many scratches, but the brightness is outstanding. It runs on 3 AA batteries.
The size is 20 cm.
It's compact for underwater cave exploration and macro photography, so you can quickly take it out of your BCD pocket and turn it on. I attached the coil myself. It stretches and retracts, making it convenient. This is a considerably used item, so please refrain from purchasing if you are concerned.
