Just replaced the Orca Green
Marine Tri-color with the Lunasea equivalent on our 44' sailboat.
After 10 years of great performance, the OGM light suddenly went very dim (about 1/10th prior brightness) and OGM did not respond to requests for assistance with this problem.
The
wiring protocol for the Lunasea is the same as for the OGM light so it was "plug and play" with the 3-wire connector on the masthead and the OGM "Master Switch Module" at the
electrical panel (i.e. diodes that provide connection to the three panel switches: Tri-color;
Anchor; and Strobe). I did have to adapt the mounting bracket by drilling new holes to fit the Lunasea.
The Lunasea unit seems to have similar brightness the OGM tri-color so, so far so good.
