I had broken two Bulbs. Or these two days later they arrived work perfectly.one of my bulbs broke during a wind storm in my string of lights. this is a great value and work great. highly recommend.Works great! Tried buying a box of bulbs from store but they won't work. Have to order ones through magic pro only for replacement bulbs! Glad they have them though!Be very careful upon installation. Bulbs may break easily. It wasn't the easiest to find the replacement bulbs either. The luminescence is far superior to any other solar lights I've had before. The option to charge the lights is also a great feature unlike any other solar lights I've had. So if you come across a dim day but know you'll have company over at night you can just charge the lights so they will absolutely last all night!Heavy duty product. Lights glow warm white. Have had these on my deck for 11 months and solar panel still working fine. I accidentally broke one of the bulbs when hanging them, but I was able to order replacements from Amazon. I have a few on hand just in case. I just bought a second set for the 2021 season.I tried and returned 3 different solar light bulb brands before spending the money and added shipping for 2 of these light bulbs. It's simple- all the other light bulbs claimed they would work in the MagicPro solar bistro lights but this is the only one that really does!Works well with the solar lights I havePurchased a set of what I thought were the correct replacement bulbs since I broke three bulbs when I opened the package. They didn’t work. I looked at the reviews where folks were complaining about the same issue. I purchased these and they worked perfect
