In winter, this year, there have been mostly windy days. Even when I turn on the underwater LED, I can't see anything underwater due to the waves and bubbles on the water's surface. This product is an actual-use LED with excellent visibility, especially strong in such rough weather. This shirasu (whitebait) LED uses directional LEDs. It drastically changes things by focusing the illumination on a shallow depth where visibility is possible. It has been said for a long time that "shirasu have a path they swim along." Therefore, securing a good spot is fierce, but this common knowledge has been overturned as a result of the power of the energy-saving LED being doubled. This is a shirasu eel-specific LED designed for enhanced visibility. It's completely different from the "underwater lights" that have been sold until now, with a new design that improves efficiency and ease of viewing, reducing eye fatigue. Since shirasu eel fishing is better on days when the water surface is rough, ① It brilliantly eliminates the glare of surface reflection. ② It concentrates most of the LED's light on the area to be caught. ③ The strong light source of the LED doesn't reach the eyes of the catchers, so they don't get tired, and there are no unnecessary things or the seabed in their line of sight. ④ By sinking the LED downwards, it illuminates the upper forward diagonal with the strongest light axis, so even thread scraps are clearly visible. From the perspective of the scooping catchers, only weak light reaches their eyes directly due to the illumination angle, while the area to be caught is illuminated with the strongest light. Energy-saving type 12v 100w Operating current 4A / hour Dark yellow LED Power cord: 5m The battery clip is a new type that is resistant to rust. This is a shirasu eel-specific LED that pursues visibility that is not affected by wind, waves, or bubbles on the water's surface. It has a structure that forcibly gathers the fish in an area that can be seen by the catchers, so it makes a significant difference in catch volume when used on the same day and in the same place as other LEDs. LEDs that don't catch fish ⇒ The illumination area is mainly the seabed, so even if they approach, they will go back after they get bored. You often see this at the fishing site. The exploded view of the "LED light bulb" is in the 6th image, and it illuminates directly downwards, so it guides the fish to the seabed. **Shirasu that gather on the seabed with bulb-type LEDs cannot be seen by the catchers.** The LED for sale sinks downwards and illuminates the upper diagonal direction with the strongest light axis. You can clearly see the shirasu swimming towards you. Even in places with waves or "foamy water surfaces," underwater visibility is not lost. Even the underwater area that should be completely invisible after the waves pass is just a state of bubbles lined up.
