In winter, there are many days with strong winds, and even when the underwater LED is turned on, the underwater is completely invisible due to the waves and bubbles on the water surface. Even when the underwater LED is turned on, the underwater is completely invisible due to the waves and bubbles on the water surface. This is an offering of a highly visible, practical 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 emission power. Shirasu fishing results are dramatically improved by concentratedly illuminating at a depth where shallow visibility is possible. Because the structure forcibly gathers the fish-attracting area to a depth that 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 / hour Incandescent LED 6m cord The breakdown diagram of the LED light bulbs often seen is in the 6th image, and the fish-attracting area is guided to the seabed. With LEDs that don't catch fish ⇒ the illumination area is mainly the seabed, so 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 a bit rough, so ① The glare of surface reflection is brilliantly eliminated. ② Most of the LED's illumination light is concentrated on the area to be caught. ③ The strong light source of the LED does not reach the eyes of the catcher, so there is no fatigue from unnecessary surroundings 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 LED being offered (the light source visible to the catcher) is a weak light. Because it emits most of the light only at the necessary 120-degree illumination angle, the efficiency of illuminating the area to be caught is four times that of a normal underwater light (360-degree illumination type). The catcher of the scoop net only sees weak light in terms of 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 can be seen clearly. 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 have passed, is only a state where soap bubbles are lined up.
