As others have pointed out, the clamps do not hold. them at the highest level to give the most tension to hold the light. If your bulbs don't have one, you can get them cheap at the hardware store - it's a 3-4 inch spring with loops on each end. It takes some fiddling to get it right, putting on goggles and turning off the power because if they don't fit they'll fly away and suddenly pushing down can cause a spark as the cord can touch something it shouldn't. Light split rings as my ceiling holes are slightly larger than average. The four stars actually have a function. My light is connected to a switch and I use the switch. You must initialize your app before submitting it to Google. Sometimes it forgets it's initialized and keeps blinking like a flash at max brightness when you flip the switch. You have to open the app and it will ask you if you want to set up the device - once you've done that it will remember who it is and you're good to go! That's always uncomfortable. It also flashes sometimes for no reason. Just a blink. The complaint I have about the app is that the UI for accessing the cool light settings is hidden and I always forget where it is. You just click on the light's name, but it's not clear if it's a link or does something. If you click anywhere else in the field, another dialog box opens. Overall, I'm happy with the lighting, and its issues are just minor annoyances.
