The Quarrow® Submersible Fishing Light produces a bright green glow directly into the water. This bright green light sets up a natural food-chain reaction by attracting small microscopic animals known as plankton. Baitfish, such as shad and minnows, are drawn to the light to feed on this concentration of plankton. Consequently, larger gamefish move in to feed on the baitfish. Draws 0.97 amps per hour.
