In winter, there are many days with strong winds, and even when underwater LEDs are turned on, the underwater is completely invisible due to the waves and bubbles on the surface. This is an offering of a practical, highly visible LED, especially effective in such rough weather. It has long been said that "shirasu (whitebait) have a path they swim along." Therefore, securing a good spot is fiercely competitive, but this common knowledge has been overturned as a result of the ultra-low power LED with doubled light output. By angling the directional LED body and concentrating the light on a depth where shallow visibility is possible, the fishing results are dramatically changed. Because it is structured to forcibly gather the fish in an area where they can be seen, it makes a significant difference in catch compared to other LEDs when used on the same day and in the same location. Low power consumption 12v 50w operating current 2A / per hour Green LED 5m cord The breakdown diagram of the LED light bulb often seen is in the 7th image, and because it is structured to mainly illuminate directly downwards, it guides the fish to the seabed. LEDs that don't catch fish ⇒ Because the illumination area is mainly the seabed, even if the fish approach, they will leave after they get bored. This is a completely different design from the "underwater lights" that have been sold until now, with improved efficiency and visibility, and reduced eye fatigue. Shirasu eel fishing is better on days when the water surface is rough, 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 strong light source of the LED does not reach the fisherman's eyes, so they don't get tired, as there are no unnecessary surrounding objects or the seabed in their line of sight. ④ By sinking the LED and illuminating the upper diagonal forward direction with the strongest light axis, even thread scraps are clearly visible. The LED being offered emits a weak light source visible to the fisherman. It emits most of the light only at the necessary 120-degree illumination angle, so the efficiency of illuminating the area to be caught is four times that of a normal underwater light (360-degree illumination type). To the fisherman using a scoop net, only weak light reaches their eyes directly due to the illumination angle, and the area to be caught is illuminated with the strongest light. By sinking it and illuminating the upper diagonal direction with the strongest light axis, the swimming shirasu are clearly visible. Even in places with waves, even on a "foaming sea surface," underwater visibility is not lost. Even the underwater, which should be completely invisible after the waves pass, is only a state where soap bubbles are lined up.
