Hi,

on or in boats those lamps are not used often, as I know. Most bulbs on
ships habe other sockets, some of them are very special.
Halogen bulbs with that MR 16 socket are rather good for ship lightening,
special inside a boat. They give a lot more light than conventional light
bulbs. I´m using them for lightning the cabin, for reading lamps....
There are adapters availible, that fit modern MR16 bulbs into older sockets,
but I think, changing the whole lamp will be best solution.
Wattage depends on use of the lamp. High wattage means decharging batteries
in a hurry. 20 watts will be enough for most lightning inside the boat.
Very interesting are light bulbs using LED technology, fitting into that MR
16 socket. They consume low power, habe a very long lifetime, but they are
rather expencive.
