This LED string of multi color lights (shown at left in photograph) uses the very small Nano size 0804 mm SMD chip. There is a total of 100 LEDs spaced approximately 1.25 inches apart and wired with a silver wire. The total length is over 10 feet. It will run on an AA battery box or the 12-volt DC current of the doll house when connected to a special adapter. It is not wired to work with an AC transformer. Because they are made with LEDs, they will last for over 50,000 hours of continuous use and they draw only 390ma of power. The string, which can be cut at any length, comes equipped with standard plug.
This model comes equipped with a battery pack; an adapter (purchased separately) would be required if you want to connect these lights to your dollhouse power source.
