SYSTEM01-3 SUPER-NATURAL COLOR Price: ¥74,800 Includes: Main unit, charger, charger adapter, and storage case (as shown in the photos). This is an underwater light from a well-known manufacturer. The main difference from other products is its ability to illuminate scenery and marine life vividly, like sunlight. The following website provides an easy-to-understand introduction: https://marinediving.com/topics/24866.html I am an instructor and certified diver, and I have used this for personal photography. Of course, I have maintained it properly. I've used it for a year, and while there are scratches on the surface, it functions perfectly. The battery also lasts for 60 minutes x 3. I feel that the operation is more stable because it has been used at regular intervals, rather than being a beautiful used item that has been left unused for many years. The light-emitting surface is almost undamaged because a diffusion filter has been attached since it was first opened. Please refer to the photos.
