Review on Joiedomi 15.8 Ft Christmas String Lights: Battery Operated 2 Pack with 50 LED Lights for Xmas Outdoor Decorations by Ann Montana

I wanted to try battery powered LED lights so I didn't have to pull extension cords outside. I was concerned they wouldn't be as bright when using rechargeable NiMH batteries, but they worked fine. Not as bright as the plug-ins, but decent. The timer works perfectly. Turn them on (8 clicks of the switch to put them in permanent mode) and they work for 6 hours, turning off and back on at the same time the next day. I charged the batteries the next day and they require a 300mah charge so 2000mah batteries can last up to 6 days before needing a charge. Probably better charge every 4-5 days. I immediately bought another pack. UPDATE: After a few weeks outdoors I returned the headlights and many of the bulbs still had water from the rain. There was also some water in one of the 4 battery packs. I'll do my best to dry them but I'm afraid the moisture could cause corrosion. I was hoping they would last a few seasons. They still work, but I'm deducting a star.
