There are a lot of opportunities to save power on a boat. Each tube bulb is using from 5W to 25W.
For example anchor light. Do you have a 10W tube bulb, and it is "on" from clock 23 to 08, it will use
Normal 10W tube bulb:
9 x 0,83 Amp/h = 7.5 Amp/h
By changing to LED bulb the same calculation will be:
LED bulb:
9 x 0,1 Amp/h = 0,9 Amp/h
