These are Lemax Reindeer Dens used last year only. There is one den per reindeer. Rudoph does not come with this set because of copyright issues. They work great and are beautiful at night. These do not come with adapters because Lemax is not adding adapters in with the new pieces they put out. I used two Lemax 4.5V control boxes which uses 6 plug ins each. The control box has a remote, so you never have to get up to turn the reindeer den lights on. You can also use AAA batteries in each one. The last two pictures are the dens lit up in my display last year. The lights with the Santa hats do not come with the dens. I'm not sure why some of the boxes have a number on them and some don't. I bought a few at Michaels and purchased the rest online. They are all approximately 7.5" x 5.7" x 4.6".
