    • Lots of Colors and Works Great
Size: 4 Pack Style: 800 Lumens, 4-Pack
These Kasa smart bulbs are awesome—bright, responsive, and the color options are endless. Super easy to control with Alexa, and the dimming is smooth. I love them, and they make any room way more fun.

    • Decent Quality TP-Link Wifi Bulbs That Work With Kasa and Deco Apps
Size: 4 Pack Style: 800 Lumens, 4-Pack
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. ... show more

    • Love Kasa!
Size: 4 Pack Style: 800 Lumens, 4-Pack
Best bulbs ever!! Easy to use. Works with Alexa. Still haven’t had to replace a bulb and I’ve had these a long time. This purchase was for my mother. Turned her noise into a smart house with Kasa products. Very user friendly!

    • Good, but some connectivity issues
Size: 4 Pack Style: 800 Lumens, 4-Pack
Review Image by Sara Sara
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. ... show more

    • So easy to hook up
Size: 4 Pack Style: 800 Lumens, 4-Pack
Absolutely the best. SO easy to hook up, and I love how I can have any color light I want, dimming, etc. We haven't had these very long, so can't speak to longevity yet, but everything else is awesome. (For reference, I'd tried different companies bulbs AND plugs to hook up to alexa and they were SO obnoxious to connect up and then whenever we moved or the power went out or even just a random Tuesday, they'd disconnect and we have to do it all over again. These were SO easy to hook up and haven't disconnected randomly yet, so 5/5 stars! But even if they were to disconnect, I'm much less bothered because they are, again, SO easy to hook up!) ... show more

    • I love these
Size: 4 Pack Style: 800 Lumens, 4-Pack
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. ... show more
