These are both tested and working. The socket is the same as a standard lightbulb. There are no maker's markings on either of them. They have what look like tiny ceramic balls on the inside filament. Oen has two pieces and the other has three. They are small bead size and white or gray in color. Approx. 5 1/4-5 1/2" long. I do not know if they have been used.
We do combine shipping when applicable. Since we sell items that vary greatly in size and weight there is not standard used for this other than the weight and size of the items combined.
We offer a large variety of items and do not specialize in any one area. The majority of our items are acquired through estates, home sales, storage bins, closeouts etc. We describe them to the best of our ability and use multiple photos to help aid you in your bidding decisions. If you have any questions or concerns please email prior to bidding as we are not specialty sellers and something that may seem obvious to you regarding an item may not be obvious to us. All items are as pictured and described to the best of our abilities.
Regarding Shipping Costs: In most transactions we use the shipping calculator so you can determine the cost of having the item shipped to you prior to placing a bid or making an offer. Shipping is not only based on the weight of an item but also on the dimensions of the item after packaging as well as where you reside (an item shipped from the east coast to the west coast will cost significantly more than an item sent within the same state).
