I have one 120V lamp in the boat and it is my "reading light" in a corner near the settee; it is on arm and I can move it to any position. Of course 120V this means it only works when I am on shore power.
I recently replaced one of my old incandescent overhead lamps with a "warm" LED and it sure looks nice... so I suspect I am moving to all LEDs. Even on "This Old Boat."
