Lamp End

I have this lamp of Edison to save energy but do not know what the bulb is called.?

It has two screws at the end of the bulb and only must be placed in the holes of the lamp and turned halfway and then breaks. What are light bulbs called and where I can find them?

go to Lowe or Home Depot, Ace Hardware, True Value, or any lighting store, both in selling replacement bulbs and in the section where they sell appliances lighting, since not all types of biulbs are in one section. take an old man, and tell the guy or girl who needs a new doo-hickey s, showing the device you want to replace
