However, many fish could see colors we couldn't see, including ultraviolet light. Ultraviolet radiation travels farther in water than we supposed. As research progresses, different fish has preferences for specific colors. The best colours of light to attract fish are green and blue. But when the light intensity is strong enough, all colours could have an ideal effect.in the dark. Fish lamp could attract fish, because the fish has phototaxis, it is easier for fish to see the bait near the hook. In fact, the fish lamp mainly attract shrimps, shrimp phototaxis is very strong, shrimp is the food of fish, shrimps come, fish naturally will be attracted. Why choose BLUERICE? 1) High brightness, Brightness stability, no color difference 2) Catering to the phototaxis of fish, high efficiency and energy saving 3) Convenient power connection: Power by Portable battery or vehicle battery 4) Good heat dissipation, fast sinking and IP68 water resistance 5) Safe and convenient operation in deep water.
