Newly hatched shirasu, drawn to bright places, gather in areas that are strongly illuminated. Due to the structure of LED chips, almost no light is emitted sideways. LED light bulbs, illuminate the spherical white frosted glass with the little light they have, creating a bright atmosphere. From the flat LED chip, light is emitted downwards at a 120-degree angle. As a result, most of the shirasu that are attracted gather within the 120-degree irradiation angle directly below, so we desperately watch only a portion of the curious shirasu that cling to the light source. It has long been said 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 latest ultra-low power LED with doubled light emission power. By concentrating the illumination on "only the depth where visibility is possible," the fishing results have drastically changed. From the user's perspective, the LED light feels insufficient (only the reflected light in the water is visible). It emits no light in unnecessary directions, focusing it on the necessary area. Popular green color. Power supply: DC 12V 10W Luminous flux: 1100LM ・Power cord: Approximately 5m (new type of battery clip that is rust-resistant) ・Body size: 130mm long, 50mm wide, 12mm thick. ・Power cord: "Red clip is positive," "Black clip is negative." ・Please secure the installation with bolts to a sturdy pipe. Shirasu eel fishing is better on days when the water surface is rough, so ① The glare of surface reflection has been brilliantly eliminated. ② Most of the LED's irradiation light is concentrated on the area to be captured. ③ The user's eyes do not receive unnecessary surrounding objects or the strong light source of the LED, so they do not get tired. The LED being sold has a 120-degree irradiation angle. The weak light is 30 degrees to each side (light source visible to the catcher). From the perspective of the scooping catcher, only weak light from the irradiation angle directly reaches their eyes. It illuminates the area to be captured with the strongest light. By submerging it and illuminating the upward diagonal direction with the strongest light axis, the swimming shirasu can be clearly seen. 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.
