20 feet, however, 8.5 feet is the lead cable, so only 11.5 feet of actual lights. It was rather disappointing.
Short length of lights, but otherwise it’s great. Hung them in an area that my other lights didn’t reach and they do the job.
Like the other reviews, I assumed that they were 20’ in length + the 8.5’ lead. Super short, didn’t reach where I needed them too. They work pretty well, but would not order again.
