Solid smart-bulb for everyday use
I installed this Kasa bulb in a lamp and it worked almost instantly — setup was easy, no hub needed, and it connected fine to my 2.4 GHz WiFi. The color-changing + dimmable features are great: I can pick from a wide range of hues or set cozy warm-white light, and brightness control is smooth. It plays nicely with voice assistants (Alexa / Google), which makes it convenient if you prefer hands-free control. The light output is bright enough for a medium-sized room (roughly equivalent to a 60W bulb), but when on colored modes it feels more ambient than ideal for focused tasks.

Lights, Camera, Action!
Easy to set up! There are multiple colors available in the app to choose from. I just got mine a couple of days ago so I'll update if needed after I've used it for a little bit. My main reason for buying it was so that I can have a small light at night when I'm out. I have a cat and I'd perfer she not be in the dark when I go out at night (don't judge me🤭). The price was nice and it works as described. Love the fact that I can set a schedule and it works with Alexa!

Bright, fun, and convenient — these bulbs totally upgrade the vibe
I picked up these smart light bulbs a few weeks ago, and they’ve already become a go-to in our home. I love how easy they are to set up — no hub needed; they just connect straight to our Wi-Fi and start working right away. What really sold me is how flexible they are. I can change the colors to match my mood, dim the lights for movie time, or brighten things up when I’m trying to focus or get work done. Switching between “cozy evening” warm light and “bright morning” daylight is surprisingly satisfying. They work perfectly with voice control (I use Alexa), which means I don’t have to fumble for a light switch. It’s super handy when my hands are full or I’m already in bed and don’t want to get up. For me, these bulbs are great for everyday living — whether I’m working from home, winding down in the evening, or just relaxing in the living room. They make it easy to create the right atmosphere without any fuss. If you’re thinking about upgrading your lighting and want something flexible, easy to control, and fun to use — these bulbs are a home run.

Good entry level smart bulb
I have over a dozen of these Kasa smart bulbs in my house, and I've used them for over a year now. Overall, these are a solid and affordable entry-level smart bulb. Installation is a piece of cake. Simply unscrew the old (standard) bulb, and screw the Kasa bulb in its place. Then follow the instructions in the app to configure the bulb with your wi-fi. To be clear about how these work: DO NOT flip the wall switch on and off. Turning the switch off will kill power to the bulb. The wi-fi chip inside the bulb always needs a small amount of power in order to receive the command to turn the light on. When you want to turn the light on from your phone app, or Alexa device, these devices will send a command to the bulb over wi-fi. If the bulb has no power, it cannot receive this command. So LEAVE THE WALL SWITCH ON ALWAYS, and simply use your app or Alexa to control the lights. Of course, you COULD continue to use the wall switch as normal, and the lights will go on and off properly. This is actually quite convenient when guests are unfamiliar with how the bulbs work. However, if you plan to use the wall switch routinely, you lose any smart functionality, and there's no point to buying these bubs. Unfortunately, the bulbs seem to have a flaky wi-fi connection, and the app occasionally loses the ability to communicate with the bulb. Every day or two, I have to flip the wall switch off and then back on to "reboot" the bulb's wi-fi chip. Then you're good for another couple days. In terms of brightness, these are advertised at 800 lumens. I have 5 of them in my dining room chandelier, and it certainly provides more than enough light for eating, and for craft projects on the table. In the living room, the ceiling fan has 4 of these bulbs, and it does seem a little dim at times when reading. I wish the bulbs went up to 1,000 lumens or more. Of the 12+ of these bulbs I own, one went bad within a few months and I had to replace it. The rest continue to work. Overall I give these a B+.

Functional and Convenient
Came ready to use for my alexa but still had to download the tp-link app. Great light and a need for bust family who forgets we dont need to pay Ga power anymore than we already do! Works with a reg lamp.

I recently purchased the Kasa Smart Bulb, and I am thoroughly impressed with its performance and features. This smart bulb has truly enhanced the ambiance of my home while being highly economical and user-friendly. Firstly, the setup process was incredibly straightforward. The bulb seamlessly connected to my Wi-Fi and integrated with Alexa without any issues. Within minutes, I was able to control the bulb using voice commands through my Echo Dot, which made the whole experience even more convenient. One of the standout features of the Kasa Smart Bulb is its energy efficiency. Despite its bright and vibrant illumination, it consumes significantly less power compared to traditional bulbs. This not only helps reduce my electricity bill but also makes it an environmentally friendly choice. It's great to have a smart home device that doesn't compromise on brightness while being conscious of energy consumption. The versatility of this smart bulb is another aspect worth highlighting. It offers a wide range of colors and adjustable brightness levels, allowing me to set the perfect mood for any occasion. Whether I'm hosting a dinner party, relaxing with a book, or watching a movie, I can easily change the color and intensity to suit the atmosphere. The colors are rich and vivid, adding a touch of elegance and style to any room. Additionally, the Kasa Smart Bulb's scheduling feature is incredibly useful. I can set it to turn on or off at specific times, which is perfect for maintaining a routine or enhancing security when I'm away from home. I also love the "circadian mode" that adjusts the lighting based on the time of day, mimicking natural light patterns and helping to regulate my sleep cycle. The Kasa app is user-friendly and intuitive, making it easy to control the bulb remotely. Whether I'm in another room or miles away from home, I can effortlessly adjust the lighting settings with just a few taps on my smartphone. The app also allows me to group multiple bulbs and control them simultaneously, providing even more convenience. In summary, the Kasa Smart Bulb is an excellent addition to any smart home setup. Its economical energy consumption, stunning color options, ease of use, and seamless integration with Alexa make it a top-notch choice. I am extremely satisfied with this purchase and highly recommend it to anyone looking to enhance their home lighting with smart technology. This bulb has exceeded my expectations in every way and has truly elevated the ambiance and functionality of my living space.

So easy to install. I used a lamp to program each bulb inside. As soon as I installed the bulbs in my outside light fixtures, the connection was instant. Looks great! My first package contained 2 odd bulbs, not smart bulbs. I was so excited to receive I never noticed until 1 hour later when frustrated and after trying every troubleshooting tip. My daughter kindly pointed out that the package was previously opened. Amazon was great to deal with and i received an unopened package 2 days later with smart bulb. Inspect the bulbs before you try to install.

Deceptive ad, does not mention the voltage is not suitable for 220v (the standard voltage in the UAE and is still available on UAE amazon). After purchase I received an email informing me of this this and recommending I use a voltage converter. By this time it was too late to cancel. Proceed with caution.

Los productos TP Link son grandiosos; tengo un router archer AX 6000, 6 interruptores inteligentes, 1 dimmer inteligente, 1 x 4 pack de smart plugs mini, dos regletas inteligentes con tres entradas, entre otros dispositivos de esta marca y no saben fallar, tienen un funcionamiento eficiente, además de que la aplicación Tp Link Kasa es bastante útil. En general puedo decir que este foco a pesar de ser económico tiene buen flujo luminoso (medido en lumen) bastante bueno, acercándose en calidad a la de su competencia "los focos phillips Hue" (los cuales tengo 1 x 2 pack), alumbra bastante bien mí escritorio, tiene una amplia gama de colores y temperatura de color (medida en Kelvin), lo empleo para uso rudo, varias horas al día, sin embargo llega a calentarse un poco, recomiendo no situarlos en sockets embebidos para que tengan una ventilación óptima. Para quienes comentan que su dispositivo pierde constantemente la conexión, sugiero que compren un enrutador TP Link de gama media (quizás un enrutador "TP-Link WiFi 6 AX3000 Smart WiFi Router" para arriba) para que tengan una mejor gestión de los dispositivos conectados a su red wi-fi, ya que inicialmente a mí me pasaba lo mismo, hasta que adquirí un buen enrutador, el router TP Link AX6000 (procuren también actualizar el firmware de su enrutador de manera periódica para no sufrir pérdida de velocidad en la transferencia de datos). Anteriormente tenía el módem típico que TELMEX provee, el cual sólo me brindaba 17 mb/s de los 200 mb/s contratados al momento de hacer el "speed test", desde que adquirí el enrutador TP Link antes mencionado el manejo de mis dispositivos es excelente, ya que gestiona de manera óptima todos los dispositivos y de manera simultánea, habiendo más de 20 dispositivos conectados a la vez (echo studio, echo dot, 4 pantallas, 2 laptops, 3 smart phones, y varias luces inteligentes Philips Hue y Tp Link), he hecho muchas mediciones de Speed test conectado a este enrutador TP Link Archer 6000 y en la banda de 5G, y puedo decir que la velocidad de transferencia de datos es de 200 mb/s en promedio, pero aún más importante, la gestión de los dispositivos es excelente. P.D. A mí me costó este smart bulb $309.49 mxn, precio imbatible para un foco inteligente de colores.

buenos focos para utilizarlos con un asistente virtual. Fácil de configurar y utilizar, en las noches ya no necesito pararme antes de dormir para apagar los focos, Alexa lo hace por mí.
