Designed for small to medium fishing and cruising boats, the Sport S3116s underwater LED produces 9,800 lumens and has a strobe pattern that OceanLED says helps attract fish.

The 90-degree surface beam angle illuminates more area around the boat, and the focused 20-degree side beam angle provides greater water penetration, making it 20 percent brighter than other underwater lights, according to OceanLED. Available in white or blue. $500. OceanLED USA, Deerfield Beach, Florida, (954) 523-2250. oceanled.com
