This adapter accepts any of the MR-16 type lamps above, allowing them to be used in any standard medium base socket. Lamps plug into holes in adapter. Tight friction fit can be used safely with lamp pointing downward. This type of light is found on many small boats. A switch selects a 20 watt clear bulb or 10 watt red light.
Bulbs are halogen double contact bulbs.
The light uses very little power, but it focuses a large amount of quality light in a small area. It is great for reading and hand tasks. The base is designed to be permanently mounted to the work surface with two screws or plugged into a cigarette lighter plug in the case of the 7 model. They have a better quality light and a longer life than standard automotive lamps. The double contact bayonet base lamps have a single filament, powered from both bottom contacts to fit most marine fixtures.
