A set of 3 smart bulbs provides very colorful lighting for the home. With 3 long-lasting LED bulbs that can be changed color via the app, a smart lightbulb is a must-have for everyone. The photo shows the assembly instructions. Pairing devices takes time. Be patient. The reward is full color lighting that can brighten up living environments with automatic color changing options. I like this opportunity. Personally, I couldn't pair lightbulbs. This may be a network error, but after an unsuccessful attempt to pair the first light, none of the other lights "blinked" signaling connection. After 90 minutes of trial and error, I gave up. For now. Maybe I'll try again. Smart lightbulbs may not be for the crazy like me... I recommend the set of 3 smart lightbulbs to anyone who has the patience and ability to get them up and running.
