I have purchased several indoor light fixtures that have unusual sized bulbs with weird bases on them. If you are not 100% satisfied with your purchase, take it back and get what you want. Prior to purchasing some of my light fixtures I studied the outside of the boxes for information about the fixture and bulb size and couldn't find any information that told me what I needed to know. When I returned the fixtures the customer service person showed me some code numbers on the box that explained the information that I needed. When I replaced the fixtures that I returned I made sure that a store employee explained all of the details to me that were hidden in code on the box.
