In winter, there are often strong winds, and even with underwater LEDs on, the surface waves and bubbles make it impossible to see underwater. This is an offering of practical, highly visible LEDs, especially effective in rough weather. The directional LED body is angled to focus light on a shallow depth for optimal visibility, dramatically improving fishing results. Low-power 12V 50W Color characteristics: Strong overall light emission Yellow/Lemon LED Power cord: 5m Battery clips are a new type resistant to rust. These LEDs are specifically designed for shirasu eel fishing, pursuing visibility that overcomes wind, waves, and surface bubbles. The "directional LED" illuminates only the area visible to the fishermen. Shirasu eels attracted to the light will gather in the same numbers with the same wattage. However, with bulb-type LEDs, they gather in the unseen, deeper areas, and "leave when they get bored" (LED bulb breakdown diagram in the 7th image). The offered LED is a directional LED that can "gather them at a visible and scoopable depth." The catch for a single night is far greater than with bulb-type LEDs. This is completely different from previously sold "underwater lights," with a new design that improves efficiency and visibility, reducing eye strain. Shirasu eel fishing is better on rough water days, so: ① The glare of surface reflection is brilliantly eliminated. ② Most of the LED's light is concentrated on the area to be caught. ③ The fisherman's eyes are not strained because the strong light source of the LED does not reach the surrounding objects or the seabed. ④ By sinking the LED and illuminating the upper diagonal front with the strongest light axis, even thread scraps are clearly visible. The LEDs on offer have weak light on the sides and top/bottom edges (the light source visible to the fisherman). They emit most of their light only at the necessary 120-degree angle, making the efficiency of illuminating the fishing area four times that of a standard underwater light (360-degree illumination type). From the perspective of the fisherman scooping, only weak light reaches their eyes directly due to the angle of illumination, while the fishing area is illuminated with the strongest light. By sinking it and illuminating the upper diagonal direction with the strongest light axis, the swimming shirasu eels are clearly visible. Underwater visibility is not lost even in areas with waves or "foamy sea surfaces." Even the underwater area that should be completely invisible after the waves pass is just a state of soap bubbles lining up.
