Have a Question? See What Others Asked

I’d like to use these in a fixture that currently is controlled by a dimmer switch. Is that okay?
If you have say 4 bulbs on one circuit, can you program each bulb individually?
Can these or any kasa bulbs color cycle? Like just loop through the various colors?
Can these be used outdoors?

These are nice

These are great so far. Setup was easy and fast. I like the app interface alot too. The dim scale on these are way better than the Feit ones, in my opinion; I always felt like Feit's 1-5% dim was way too bright, but Kasa's is perfect. My only complaint is that I feel like the Kasa red setting is a bit too orange, and there doesn't seem to be an option on the color circle for a more intense red. I usually sleep with red on at night, so I'm a tiny bit disappointed. Orangey red is nice too, though, just not as relaxing for me.

Great smart bulbs

The colors are good and they are very bright.The Kasa app it tells you to use is very good. Definitely the best smart lighting control app I have ever used, but I don't think it supports any products outside of the brand and I wasn't able to get these bulbs to connect to other apps.The connection process is very simple and it holds your hand through every step. the app will bring you to the wifi screen to connect to one of the bulbs temporary wifi hotspot, then you go back to the app and it will ask you to connect to your wifi. Then it does the rest for you.Will buy again

KASA GETS IT RIGHT AGAIN

These are the latest KASA smart items I use daily. I had to replace a set of Sengled bulbs that lost their "smarts" after a power outage. I missed voice control even though I could still switch them on. The "everything is made in the same fab in China, the only difference is the software" holds especially true here.KASA smart products are my favorite in my very smart house. Easy to set-up, made easier by virtue of the app already populated by the other KASA products, and their superior software that has never given me any problems with years of use and many different products.

Good bulbs—but not for Apple users

These Kasa smart bulbs are solid if you're deep into the Alexa or Google Home ecosystem. Setup is fast through the Kasa app, the colors are bright and accurate, and the scheduling and automation features work smoothly. Dimming is clean, no flicker, and the app interface is user-friendly with plenty of scene options. The bulbs themselves feel well-made and responsive over Wi-Fi.But here’s the catch: they don’t support Apple HomeKit. I ended up switching to a HomePod mini after ordering these, and that basically made the bulbs useless for me. Without Matter or native HomeKit support, there's no clean way to integrate them into Apple’s smart home system unless you want to run third-party bridges or workarounds—which I didn’t.So, if you’re an Alexa or Google user, this is a great buy. If you’re in the Apple ecosystem, skip it and get something Matter-compatible. I returned mine for that reason alone.

They light up my life!

I've been buying Kasa light bulbs for a few years now and have not been disappointed. I like how the setup is easy, and I have no problem navigating the app and connecting it to my Alexa. I like how I can pick different colors and levels of brightness, making each room unique. I picked up this four-pack because I thought it was a good value.

Doesn't flicker with dimmer switch YAY!

FINALLY smart bulbs that don't flicker with my dimmer switch!! The set up is a little weird, but I already have other Kasa products and app, so I figured it out. You have to add each bulb separately and then if you want to create a group, you can. These are great. You can adjust the brightness to be more warm/soft and less bright. So far, so good!!

LOVE these lightbulbs!!

They integrate well with the alexa app and I use them in my lamps that I was trying to have connect to alexa via plugs (and would never stay connected). The light has so many options; from colors to brightness adjustments. All can be done through your alexa voice commands (Alexa, turn the office light brightness up or Alexa, set office light to purple)
