BoatingLAB Tests: LED Lights

LEDs make navigation brighter and less power-hungry.

Courtesy Lights
Courtesy lighting, especially red, white or amber colors, mounted in such a way as to be confused with navigation lights can be dangerous. So, mount them low in the cockpit and in places where lighting is indirect for best results.

Glossary
Milliamp: One-1000th of an amp. Most LED navigation lights burn 80 to 100 milliamps, or about one-10th or less
than what an incandescent light burns.

Candela: An English standard measure of light intensity. We converted lux/lumens to candelas.

Two-mile lights: Most navigation lights are certified to give a certain intensity at two nautical miles to meet United States Coast Guard standards. Lights that emit 4.3 candelas at 16 feet meet this test.

Sidelights: These are the red or green lights placed on the hull or other structure in a way that they illuminate 112.5 degrees from dead ahead to just aft of the beam. They should not both be visible at once — even from a nearly dead-ahead orientation to the viewer.

Submersible lights: All lights mounted below the sheer line must be submersible to Coast Guard/ABYC specs.
