Purchased in 2017, it’s now well into 2019 and these have worked flawlessly with my ecobee 4 Alexa voice command and after several power outages. They are one of the most reliable smart home devices I have installed.
I have changed my review from 3 to 5 stars because the connection dropping seems to have stopped and when I power the light off and on again the connection seems to reconnect its self now. I was able to save our router password directly into the app for all paired light bulbs so re connecting after a power loss or has become easy! I have since purchased three more additional LB 110 bulbs and through some confusion and difficulty I eventually managed to pair them through the Kasa app and to Alexa. When pairing multiple light bulbs be prepared to only power on and pair one at a time as only one will show up at a time in the WiFi settings.
More importantly I was able to group together lights that are in the same room or in the same light fixture for easy voice command operation. Additionally I can easily create scenes that auto dim my lights and change to my desired brightness. I love that it allows me to dim my normal bedside lamps.
This was the fist smart light device I have purchased and I bought it because it didn't require the use of a hub (smart things, wink etc...). Setting it up was fairly easy and pairing it with Alexa was slightly confusing.
1. First you must download the Kasa app
2. click on the device you want to pair with Alexa
3. Click in the upper right hand corner on the three lines with circles on them aka "settings"
4. Click on "remote control" and you will be prompted to register for an account
5. Verify your account via the email you are sent
6. reopen the app and swipe to turn on the remote. I kept trying to push and i kept running into error messages.
Why I chose these over the Phillips Hue is because they don't require the additional use and energy drain of an extra bridge/hub. However if I would have outfitted more than 4 lights in my house then it would have been cost effective to have purchased the Phillips Hue starter kit and four pack smart bulbs.
UPDATE: The good news is that the bad news has been resolved!!
The bad news!!!
It is important to understand that if you manually turn off your lamp or other fixture then this will deprogram the light bulb from your router. Ideally I would like to have one app to control all of my light bulbs but these do not seem to be practical because we live in a highly prone power outage area where we lose power at least six or more times a year and we would have to re program four different light bulbs each time. The programming processes is quit lengthy requiring your router password each time. I wish the router password would auto save into the app and in that case I would gladly outfit out home with these bulbs.
The LB 120 seems more gimmicky than useful, the light doesn't seem to actually provide any increase in brightness as much as it does color change. The one benefit is that the cooler or "bright" light setting seems more appropriate for day time use.
I will be uploading a video showing the range of color changes through the 9 different colors as well as the dimming ability. The worst is that you can't set up motion sensing triggers without buying an additional hub :(
