We added a third O-ring and modified the cable gland on the basic model of this light before adopting it as the basis of our own LED anchor light. The O-ring sealing system is such that the lens is virtually inseparable from the body, basically a sealed unit. But that's OK because the LED cluster lasts at least 35,000 hours, more likely 50,000 hours, and that's 17 years of continuous anchoring!
We had to have it tested against the appropriate European Standard for anchor lights – it has to satisfy the Colregs as well as EMC standards – and it has its Certificate of Compliance.
Who's a clever little anchor light?
