Review: Independent Bulb/Plug Functionality - Really nice quality. I love that the electrical outlet is controlled separately from the bulb pull-chain. That way, I can turn on and off the bulb socket independently from the power outlet, which is what I wanted for my garage setup.
Review: Works Perfectly! - Super simple to use. We replaced our flush mount lights in our garage that we bought from a warehouse with these sockets. Love that we now have extra outlets for some of our chargers for battery operated tools. Also has a nice long pull chain for easy on/off. We replaced our flush mount lights with the 5 panel led adjustable lights (also desertcart) and now we can actually see in our garage!! Woowhoo!!

### ⭐⭐⭐⭐ They Work
*by K***N on January 2, 2025*

I needed to replace my old lighting fixtures in my garage. These have so far worked well. They were easy to install. I like that the provide additionally outlets should I need them. The pull-cords are work well too, thought I won't likely use them much due to the height of my garage ceilings. I'd definitely recommend. I cannot say yet how long these will last, but should they prove to have good longevity, I'll come back here to update to 5 stars.
