This underwater green fishing light is designed to attract crappie, squid, and other fish species during nighttime fishing expeditions. Compatible with Milwaukee M18 batteries, this 13-watt LED fishing light delivers 1512 lumens of bright green illumination that penetrates deep into the water to draw fish to your location. The green wavelength is particularly effective for attracting baitfish and game fish in both freshwater and saltwater environments. This dock light offers a convenient battery-powered solution for anglers who want portability without being tethered to shore power. The robust construction is built to withstand submersion and harsh marine conditions. Simply attach your compatible Milwaukee M18 battery and deploy the light in your fishing area for enhanced catch rates. Perfect for dock fishing, boat fishing, or ice fishing applications. Note that this product does not include a battery, so you'll need to use your existing Milwaukee M18 battery system.
