These lights are amazing. They work on Salt water!!! The light strand is 32 feet long with 100 LED lights. There is a large red plastic house. You will it with water and add salt and it lights up. There ae little zip top baggies included to measure the salt needed. The water and salt need to be replaced about every 2 weeks. I have never seen anything like these before and everyone who sees them are amazed as well. The house can be set on a table or there is a ribbon included to hang the house like in a tree or on a fence for outside use. The light stand is waterproof.
I received this free but am not required to write a review, but I decided I should let people know about my experience with it.
