LED Dive Light Adjustable Brightness Uses 8 AA Batteries As shown in the image, the light has been tested and confirmed to work in a bathtub without any water leakage. Batteries are not included. Used for diving a few times, the last time was about 4 years ago in the Okinawa sea at a depth of about 20m. Since then, it has not been used, so it is unknown whether it can still withstand use in deep water. The accessories are all shown in the photos. On the left side of the main body is the screw for fixing the grip, the battery holder is on the far left, and the dimming filter is on the bottom left. The rubber cap in the center is used to help open the main body cap if it becomes stuck due to water pressure. The original grip, spare O-rings, and grease are not included. Please purchase the direct base, clamp, ball adapter, and underwater housing mounting bar as a set. All have signs of use. One of the screw threads on the screw that fixes the ball and the direct base is stripped. The remaining screws are stuck due to salt corrosion and cannot be removed. There is a slight gap between the direct base and the underwater housing mounting bar, possibly due to salt corrosion. The mounting screw bar is silver and does not fit this direct base, but I will include it in case you can use it. Photos of the light in actual use underwater are for reference.
