LED Running Lights – Saving The Environment 1 Bulb At A Time

While much larger initiatives are needed to make shipping more environmentally sound, the little things add up. Don’t believe me? Ask any Engineer who has played the efficiency contest, a game where each on duty engineer goes around the ship turning off lights to increase the vessel’s fuel efficiency during his watch. The object of the game is to obtain better efficiency figures than the last watchstander.

Or was the game just intended to confuse the Deckies? (We really need an Engineer blogger here at gCaptain… any takers?).

Panbo brings us a small improvement in energy conservation that, if deployed on ships worldwide, may have a lasting improvement. They write:


Last winter, thanks to Lee Guite of East Boothbay, I tried some LED bulbs Lee used to replace the incandescent ones in the Aqua Signal nav lights aboard his Dulcinea. Lee got pretty carried away researching available replacement bulbs and the ones he finally chose were “flux” models from the LED Shop in Australia. In the photo above I was trying to get a camera comparison of his steaming light versus an OGM combo LED running light. They both seemed fairly effective, but now the LED Shop has more powerful SMT bulbs, and Orca Green Marine has dropped the multi-LED models altogether in favor of single LED lights. I don’t know much about LEDs, but they do seem to be in a state of rapid technological change, which means that one LED may perform quite differently than another, and none of them may be what we’ll be using a few years hence.
