Accidentally bought the wrong size bulbs for the lamp (wholesale). I broke one of the new bulbs during an unsuccessful installation and didn't want to return the product so I bought this adapter. The lamp can be extended a little further, but works great with this new base. The price was fair, but you should note that you only get 1 base. The image of this item may lead you to believe that you will receive 2, but this is not the case.
