This item is a 100W LED designed to be powered by a standard 12V battery, utilizing a DC-to-DC step-up converter. The listing includes a DC-to-DC step-up converter to allow power from a standard 12V battery. Please note: Due to an incident where someone submerged the voltage converter and LED in water, sales have been suspended. The 12V to 36V conversion process generates heat. **Do not pour water on the converter if it becomes hot.** This is the smallest 100W LED capable of producing an intense light. By focusing the light on a shallow depth where visibility is possible, the fishing yield will drastically improve. From the user's perspective, only the reflected light in the water is visible. The light is not emitted in any unnecessary directions, but is concentrated on the required area. This is a popular green color. Power: DC12V input ⇒ Operating voltage DC36v **The voltage is increased by the included converter.** DC36v 100w ・Power cord for converter: approx. 1.1m ・Power cord to LED: 6m (New type of battery clip that is rust-resistant) ・Dimensions: 162mm (length) x 93mm (width) x 13mm (thickness) ・Power cord: "Red clip is positive" and "Black clip is negative." ・Securely mount to a sturdy pipe with bolts. For whitebait eel fishing, rough water conditions are preferable. ① Effectively eliminates the glare from the water surface reflection. ② Concentrates most of the LED's light on the area to be fished. ③ The strong light source of the LED does not reach the eyes of the fishermen, so they do not get tired. The LED being offered has a 120-degree beam angle. The light source visible to the fishermen is weak. From the perspective of the whitebait eel fishermen, only a weak light reaches their eyes due to the beam angle. The area being fished is illuminated with the strongest light. By submerging the light and directing the strongest light beam upwards and diagonally, the swimming whitebait eels are clearly visible. Even in areas with waves or a foamy sea surface, underwater visibility is not lost. Even in the water after the waves have passed, where nothing should be visible, only bubbles are seen.
