Saving those 5 watts per bulb, equivalent to less than one amp, is good but how much should one invest to achieve it?
I think it depends on how you will use your boat, and what that power reduction does for you. Me, I have been doing long-distance sailing and racing
, and my solar panels
only provide about half of the power I need when underway. The deficit is replaced by running the engine
, about one hour / day. When racing
is out of gear
. I carry enough fuel
for battery charging
, but it's not a great way to run the engine (and it's noisy), so I want to reduce my power consumption.
I replaced my tricolor, and about half of my cabin
lights with LEDs. The tricolor makes a huge difference, and we use the LED cabin
lights when at sea. Of course we keep the cabin lights to a minimum when sailing so we don't ruin our night vision.
Anyway, changing to the LED lights
, and other power-reduction efforts, reduces my engine-charging time. To me that's worth it. You should of course make your own cost-benefit decision.
