National Artcraft's fun and festive Halloween light ornaments are the ideal addition to your Halloween ceramic tree! Our spider light ornaments measure 5/8" tall x 1" wide x 7/8" deep with a stem that is 3/16" in diameter by 7/16" long. Since most ceramic trees are handmade, they are all uniquely different. Hole sizes are not consistent on every tree...or even on every branch of the same tree! Some lights may need adjusting in order to fit into an uneven hole. Sticky craft dots or a drop of craft glue can help keep lights upright in oversized holes. Our stem sizes are industry standard. You can decide which size bulb is the right one for your tree size. The larger the tree, the bigger the bulb. A US company in business since 1949, National Artcraft is a name you can trust. These fun spider lights are the ideal addition to your ceramic holiday tree.
