The Best Smart Bulbs Around, No Hub Required!
These have an amazing range of vibrant colors to choose from, including the full range of white lighting options to match whatever pre-existing bulb temperature rating you have in your house! Also, they are BRIGHT! The setup is a breeze with the Kasa app and creating schedules or grouping devices together to function in sync is a snap! We have an older set of these that are going strong indoors for about 5 years now. Our newest set is used outdoors in covered fixtures and has been exposed to freezing weather without fail. Response times for on/off functionality or color changes are immediate and we've had no down time with our wifi connectivity to these devices. There's been no phasing out of cross compatibility from our old bulbs to our new set. We sync the bulbs together or use them separate without fail and they function as intended every time!

Work great and Easy to setup.
These light bulbs work great. Easy to setup and the color options are fun for movie time or just goofing around. The main thing I like about them is that you can dim them without out any special light switches, and they work seamlessly with Alexa.

Decent Quality TP-Link Wifi Bulbs That Work With Kasa and Deco Apps
I purchased these bulbs for three reasons. First, they were on sale during Amazon Prime Days. Second, being TP-Link Kasa products they work with my existing Kasa App and are also compatible with the Deco router app so I didn't need another app (TP-Link? We don't need Kasa, Deco and Taco- consolidate them already.) And Third, and most importantly, SengLED finally completely and utterly self destructed and stopped working with the Alexa infrastructure. These four bulbs on sale cost less than a two pack of the SengLED brand which require a Zigbee hub that doesn't work without the SengLED back office- which is basically dead now. For the bulbs themselves, they are slightly smaller than old fashioned bulbs, so don't try using them in a lamp that has a spring-grip shade. Setting them up is simple, have the Kasa or Deco app open, select add a bulb of this model and turn the bulb on. You will connect to it via Wi-Fi and then setup will take a couple of minutes depending on how slow/busy your local network is. On my Deco (TP-Link) network, the bulb took about 30 seconds to connect and appear. I haven't had a problem with the bulbs in the month they've been operational, so they already are doing better than the old SengLED bulbs ever did. And even when my internet connection is down; these bulbs still seem to work okay since they are controlled by the Deco routers (note: I've since moved my other Kasa devices over to the Deco app because controlling them from Kasa they do stop working if the internet connection is down.) I've been pretty please with most of the TP-Link hardware I've purchased over the years, and am glad the bulbs are apparently reliable as well.

Good, but some connectivity issues
The Kasa Smart Light Bulbs offer a convenient and customizable lighting solution with their full color-changing and dimmable features, compatible with Alexa and Google Home. However, while they have their merits, their reliability in staying connected to the internet leaves something to be desired. On the positive side, these bulbs provide a wide range of colors and brightness levels, allowing for personalized lighting to suit any mood or occasion. The integration with popular smart home assistants like Alexa and Google Home adds to their versatility, enabling convenient voice control for seamless operation. That said, the inconsistency in maintaining a stable internet connection can be frustrating and impacts their overall usability. There are occasions when the bulbs fail to connect or become disconnected from the network, disrupting the intended lighting settings and requiring manual intervention to reestablish connectivity. Often just one will disconnect, meaning I can’t control them both at the same time. Other times, both disconnect. While the lack of a required hub simplifies the setup process, it seems that the reliance solely on a 2.4GHz Wi-Fi network may contribute to the connectivity issues experienced by some users. It's worth noting that in environments with multiple smart devices or interference, these issues may be exacerbated. In conclusion, the Kasa Smart Light Bulbs offer a decent lighting solution with their color-changing and dimmable capabilities, enhanced by compatibility with popular smart home platforms. However, the inconsistency in internet connectivity detracts from their overall reliability and usability. For users seeking a seamless smart lighting experience, it may be worth exploring alternative options with more robust connectivity features.

Reliable and stable
I’m a big fan of Kasa products, and these full-color smart bulbs continue that trend. They’ve been reliable and stable, staying connected without the dropouts I dealt with on the FIET bulbs they replaced. Colors are vibrant, whites look clean, and response time is quick through the app and voice control. Between these bulbs and my Kasa switches, everything works together smoothly. Solid performance, easy setup, and dependable day-to-day use. Another win from Kasa.

I love these
These smart bulbs are bright, responsive and super easy to set up with the Kasa app. The color range is wide and the dimming is smooth, so it’s simple to switch from warm light to full color scenes. They connect reliably on 2.4 GHz and work perfectly with Alexa. The build quality feels solid and the bulbs run cool even after hours of use. A great set if you want hassle-free smart lighting with lots of customization. Not expensive at all.

Still in working condition after 3 years.
These Kasa smart bulbs were super easy to set up and work great with Alexa and Google Home. The colors are bright and fun, and I love being able to adjust the brightness and scenes from my phone. No hub needed, just Wi-Fi — very convenient. Great value and highly recommended!

Easy to setup, work well. Bought these for our son for his bedroom. Much easier than messing around with strip lights. We have some Kasa smart switches and outdoor times and they work great with the Kasa app. The app is easy to use and setup, also works with Google home and Alexa.
