I added these Outdoor Solar Disk Lights in the  Slate Rock color to my palm tree planters. Not so much for added light but just for an added  look. I do like the setting they make glowing up at the palm trees in the planters. I did get the slate rock color so I will add some stones in the pots & the lights will be camouflaged in the planters for a nicer day time look. 
Now the lights are 4 to a package which if using for lighting up an area, would need more than 4. They are bright but don’t throw off a strong light but a nice light to guide a walkway. My original plan to use them was for my pool step up to the deck but The lights only stake to the ground or just lay on the steps. I couldn’t attach & remove them ( when needed)  So they became a nice decor feature instead. Which I like. They look nice, it is a nice added touch
