Reducing navigation light power consumption and enhancing reliability


Be the first to comment

What is the issue?
Running a suite of navigation lights through the night whilst under sail can consume a large amount of a vessels battery capacity. So much so that power conservative sailors in remote waters have a tendency to turn off navigation lights to avoid the power drain.

Why address this?
Reducing any major power draw on a vessels battery is a major benefit, especially so if it also reduces a temptation to resort to unsafe practices.

How to address this?
Implement energy efficient Light Emitting Diode based (LED) based navigation lights.

LEDs are between five to ten times more power efficient than conventional lamps. They are also more reliable having a longer service life, typically between 10,000 to over 50,000 hours. Also as they are made up of multiple individual LEDs it is statistically highly unlikely that they will simultaneously fail as is the case of a filament bulb. Thereby they offer a higher level of guaranteed service availability to a vessel.
