I haven't tried operating them on DC power yet but the new LED light bulbs seem to work OK, draws less power, runs cooler and has no filament to break. Right now they are way too expensive ($13.00 each) to use in large numbers unless they are drastically reduced in price or donated. I currently use two of them in a ceiling fan and so far so good.
I haven't posted on the forum for a long time but I have an idea that could be used to cool the FM engines on all of the subs that are either in the water or on land. The idea involves using radiators from big trucks , existing piping in the sub, and an electrically powered fan pulling air through the radiators. This idea would only be feasible if there is enough room under the wood deck of the sub, cost of materials, and permission of the Navy.
