This is a Lopolight LED masthead light with a single lens, giving a 225° white beam rated at 5 nautical miles. It is certified for vessels from 20 to 50 m and mounts on horizontal surfaces. The housing is machined aluminum in a black finish, with cable gland outlets at the side and bottom.
Our take
A 5 nautical mile, 225° masthead beam from a single lens is certified for vessels of 20 to 50 m, so this is a light for larger craft, not a small boat. The side and bottom gland outlets give you a choice of how the cable leaves the base.
From our buying guide
The lights a boat must show depend on its length and how it's being driven. A sailboat under power is a power-driven vessel and shows power-driven lights.
Check before you buy:
- The label gives its visibility in nautical miles, and that range meets the minimum for your boat's length.
- The maker rates it for boats of your length.
- A replacement LED is certified with the fixture it's going into, since the Coast Guard warns that replacement lighting may not meet the rules.
