The bulb that prevents us from interrupting my remotely working husband
I bought this bulb for my husband, who works remotely. His office space is in the basement near the laundry area, so the rest of the family was having to creep down the stairs to make sure we wouldn’t be interrupting a meeting or call by going down there to work on our laundry. I had been looking for a way for us to be able to tell immediately whether it is okay to go downstairs and stumbled upon this listing. It sounded like the perfect solution since the hall light is right outside the door that leads to the basement.Once my husband put the bulb in the light fixture, he downloaded the app and set up the connection. He was so excited when he could change the colors with just a tap on his screen. The available widget is perfect for this! The whole family knows that if the hallway is glowing red, we’re going to have to wait to take care of things downstairs. It does exactly what we wanted and expected it to do.It did disconnect from our Wi-Fi once, but it was so easy to reconnect that it wasn’t an issue. Sometimes connections just need to be reset and this might have been one of those instances.I would definitely buy this again for both this same situation or if another area of the house needs a visual alert.

Poor wifi range
These lights are great! One drawback, which took me some time to figure out is their wifi antenna is significantly less effective than other wifi devices; probably about 50% reduction in effectiveness compared to my phone. I had devices on my front porch and garage which in worst case were about 35′ away from my TP Link range extender (which is working great unlike other range extenders I’ve tried) and they kept cycling betwween online and offline. Turning the front porch / garage light switch off then back on seemed to resolve the problem for about 1 minute, then 3 of the 4 devices fell off the network again. The one light that didn’t seem to have this problem was the closest (about 15′ away) to the range extender. All 4 devices reported no bars in the RSSI (signal strength) area of Tepo app (just the dot was illuminated at the bottom of the ‘bars’ icon). Moving the range extender about 15′ closer to the 4 bulbs resolved the problem. Signal strength reported one bar for all four bulbs and now they work reliably. Range extender is on our hallway about 5′ from the front door, whereas when they weren’t working the range extender was about 20′ from the front door.

So many uses and works perfectly
I love these bulbs, I’ve bought several now. I originally purchased them because my kid’s lights and fans are on the same switch, so rather than pulling the chain to turn the light off if we want to leave the fan on at night, we can turn the light off from our phone. They also like to play around with the colors. I was also going to purchase new dusk-dawn fixtures for my outdoor lights, but I put these bulbs in instead and they work perfectly. I am able to set them on a schedule to turn on at sunset and turn off at sunrise, or you can adjust based on sunrise/sunset (for example, turn on 10 minutes before sunset), or set your own time. It’s also fun being able to do different colors, like red white and blue for 4th of July.I also set one up in the hallway outside of my office working from home to have a red light when I’m on a call or cannot be bothered, and a green light at the end of the day when it’s okay for the kids to come in while I wrap a few things up. So we’ve found a lot of uses for these bulbs and have had zero complaints.I’ve had no issues connecting to wifi or setting up any of these lights, even the ones outside remain connected. One of my kids flips their switch on and off repeatedly, which resets the light but even that is as simple as reconnecting to the lights wifi signal, and the light will retain all of its settings once it’s paired again. Initial setup is very easy, connect your phone to the light’s wifi signal, select the type of bulb and it’s good to go. The bulbs react instantly when changing a setting from the phone.The Tapo app is pretty easy to use, we also have it for our video doorbell and cameras outside, so all of the lights and cameras are on one app, and we’re very happy with all of it now about a year in. We’ve also had temps down to -20F and up over 100F and the bulbs outside have had no trouble.

110V not 220V – returned

The light was super easy to set up in the tapo app with the reset of my device connecting to the Wi-Fi was straight forward. Colors are perfect. The only thing is I would increase the brightness for the light to be better.
