INON LE700-S INON Underwater Light Set includes case, lens filter, and grease. A submersion test was conducted in a hand wash basin with water filled to a depth of 10cm for about 5 minutes. There was no overheating, contact failure, or water leakage, but a deep-water test has not been performed, so no guarantee can be provided. Thank you for your understanding. The items included are only those shown in the images. Batteries are not included. Many diving equipment items are available. Discounts are available for combined purchases.
