There are quality marine LED lights, and there are others. I reached out to Hella Marine's Duncan Stirling for additional insights. According to Stirling, "well-constructed LED nav lights offer boaters increased vibration and shock resistance, reduced heat, and long-term reliability. When comparing LED products, be sure to select those that meet the IP67 waterproof standards and employ ultradurable materials, such as marine-rated wiring, to resist harsh marine conditions and UV radiation. For navigation lights specifically, make sure the lights meet U.S. Coast Guard requirements or don't buy them." Also, look for CE certification on LED products, which ensures that they will not create electromagnetic interference with electronics such as your VHF or fish-finder screen.
