String of LED lights with multiple uses. You can use them to light a room/roombox or string lights on a Christmas tree. I have even used them to light Halloween pumpkins and other miniature lawn ornaments.
The string is 4.5 feet long and has 12 LED lights on it. It uses 2 replaceable CR2032 batteries, which are included. Over 20 hours of light with included batteries. LeD lights are submersible (power pack is not), but this does reduce the number of operating hours). On/off switch is very handy. Small battery case is easy to hide (may be black, white or clear). Copper wire holds its shape. LeD lights are rated at 25,000 hours. Submersing the lights can reduce the battery life by 7-8 hours.
