In winter, there are mostly strong winds, and even when underwater LEDs are turned on, the underwater view is completely obscured by the waves and bubbles on the water's surface. This is an offering of practical, highly visible LEDs, especially effective in such rough weather. By angling the directional LED body and focusing the light on a shallow depth for visibility, the catch rate of whitebait will drastically improve. Low power 12V 50W Yellow/Lemon LED with strong overall light emission due to its color characteristics. Power cord: 5m The battery clip is a new type that is resistant to rust. These LEDs are specifically designed for whitebait fishing, pursuing visibility that is not affected by wind, waves, or bubbles on the water's surface. White light provides excellent visibility even for very small objects, but for older people, white light can cause eye fatigue because it makes even plankton and tiny debris too visible. A slightly colored light, such as incandescent or yellow/lemon, makes it easier to see for extended periods. The "directional LED" illuminates only the area visible to the fishermen. Whitebait attracted to the light will gather in the same numbers with the same wattage. However, with bulb-type LEDs, the whitebait gather in the unseen deep areas, and "leave when they get bored." The catch for one night is far greater than with bulb-type LEDs. This is a completely different design from the "underwater lights" that have been sold until now, improving efficiency and ease of viewing, and reducing eye fatigue. Whitebait 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 line of sight, so there is no fatigue. ④ By sinking the LED and illuminating the upper diagonal front with the strongest light axis, even thread scraps are clearly visible. The LEDs being offered: The sides and top/bottom edges have weak light. Most of the light is emitted only at the necessary 120-degree illumination angle, so the efficiency of illuminating the area to be caught is four times that of a standard underwater light. From the perspective of the fisherman, only weak light reaches their eyes directly due to the illumination angle, while 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 whitebait is clearly visible. Even in areas with waves, or on "foaming sea 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.
