So we now have some LED lights (mains only) in the aft cabin and the corridor/tunnel to it. Got them from Costco, 3 individual strips with one of them as the controller. Wave your hand in front of it to turn them on or off. Going to be very useful for boatyard winters, especially until we have got the 12 volt wiring installed.
Plus we also have our new infrared radiant heating panel installed. Just need to get some batteries for the wireless timer/thermostat. Time will tell if it is as efficient and effective as the very bold claims.
