Do LED lights have a plug?
They just last a long time. LEDs draw very little power so they can run for a long time on a small battery without any issues. There is no need for a bulky wall transformer and a wall plug to light your project.
HOW LONG CAN LED strip lights stay on?
LEDs have an unbelievably long expected life-span, compared to both incandescent and fluorescent lights. With an average life-expectancy of some 50,000 hours, LED strip lights will still be burning bright in 17 years’ time, long after their traditional counterparts will have expired.
