I had purchased a few solar chandeliers from a different seller, and before too long the removable solar component in each solar chandelier had died. There were no specific solar replacement parts available, so I searched Amazon and found these super fun color-changing solar components - and it turns out these are close enough to the same size and shape and functional design that I needed to work! I'm very glad I gave these a try and HURRAAAAY these solar light components work GREAT, look GREAT, last great, and while it took some getting used to, the changes in color very fun. I had to get used to the change in colors - it's a bit like Vegas light show when you use all the colors, but they are so fun especially for holidays that now I wouldn't want anything else. Really like these for brightness and longevity too, great price, and after I think after 6 months of use it's commendable to say every color still working! Note: We don't get a lot of rain or extreme weather here, but we've had enough to test the longevity for moderate climates and they are still working just fine. -And the programming of the different light choices not too difficult to figure out - there is a mode button so you can choose different light changing modes or even to keep the light to one particular color. -So you don't have to do the full Vegas light show every day (or at all) if you don't want to :) Definite thumbs up - and kept my solar chandeliers out of the trash heap and if these break I would buy them again, might even buy an extra set to have handy just in case :) Hope this is useful info for you :)
