See the image below. This is from a lamp. Clearly it needs some kind of adapter to go into an outlet (I assume it came with one many years ago). Any idea what the name is of the kind of adapter I need? And do I need to pay attention to voltage, watts, etc when making the purchase?
Here's the label that sits right under the lamp. It reads
50W Smaller 12V Type T Bulb, with various markings underneath it.
And finally, here's the lamp itself.
