Sengled WiFi Color Changing Light Bulb, Alexa Smart Light Bulbs that Work with Alexa & Google Assistant, A19 RGB No Hub Required, 75 W Equivalent 800LM CRI>90, Set of 4

These are great. I ordered a different brand because these weren’t in stock at the time and I ended up returning the others. These are so easy to set up! You will need your password for your home Wi-Fi ready. I downloaded the app and it walked me through. Also, when it reads ‘searching may take a few minutes’ after several minutes I hit ‘cancel’ at the bottom and it found a connection right away so when I was syncing the others, I’d let it say searching for a few seconds then I’d hit cancel and it would sync it right away. So doing that made the process quicker for me. Maybe I didn’t have the greatest Wi-Fi connection, but for some reason the cancel button that appeared at the bottom of the app helped to speed things up for me.

These are great. I connected them to our Amazon Alexa device and use one over our door with the doorbell camera. When someone presses the doorbell, we can change the lighting (brightness, color, etc.) from the other end of the house and view whoever is there more clearly. You can even set the lights to switch from red to green to red during Christmas season, or to cycle through all the colors continuously.

These work good but sometimes flickers and not very bright

These lights are a game changer! I love the versatility is color and brightness. The quality is great and they are easily controlled in the app or by Alexa. Dimmability is great. They don't put off heat either.

Muy buenos bombillos

I have updated my review because of the requirement for a "positive review" to receive a free product from them. it's unethical and amazon should not allow the practice.It's a huge decision figuring out which smart bulbs you want to buy, because you're probably stuck with them/the brand for a long time!! So I did my research on what I thought were the best/least expensive brand and decided sengled was "good enough"I went for the wifi option without a hub so everything is connected directly to my router. I currently have 10 lights hooked up to my router.I got my bulbs on sale for 20.99Installation went very well! Took me about 20 minutes to set up 10 bulbs. I downloaded the app, plugged in the bulb. Added each bulb and each bulb took about 30 seconds to a minute to fully connect. I had to reset a few bulbs which all you have to do is turn the light switch on and off 5 times really fast. It worked, but I could see how that could be annoying for some people if you accidentally reset or if you only want to reset one bulb, you'll reset all of them hooked up to the switch. I wish you could connect multiple bulbs at once, but you must do them individually, and it's actually easier to plug in one at a time.Connectivity. My Router is definitely a top model router, so I wasn't expecting any issues with connections, but I still find them to be a tiny bit spotty. 99% of the time they work the way I want, but sometimes the light's won't do what I ask right away unless I turn them on and off or wait a while. This is something I'll need to wait and see how they perform.One other thing I've noticed is you'll experience a bit of lag time when you turn your switch on to when the lights decide they will turn on. I think they turn on, connect to the router, then decide what color and if they should be on or not. It's about a quarter second or so, but it's not instant like non smart bulbs. When multiple bulbs are connected to the same switch, each bulb will act independently and it can be weird having very slight variations in the timing of each bulb turning on. The off switch is instant though.Functionality of the bulbs is pretty solid. They have virtually infinite colors, 100 brightness options 1%-100%. It's really fun messing with the colors and brightnesses. Each color can be different brightnesses as well. You can group bulbs in rooms, set timers, different color coordinations with scenes, wake up mode and sleep mode. The only ones that I'll want to use is the different scenes.I had hoped to see a rainbow/color changing option just to show off the bulbs or have some fun with them, but there is no such option I could find. I hope sengled adds this option to the app at some point.I don't have a lot of experience with other smart bulbs, but I'm pretty happy with my purchase. They are fun, pretty easy to set up and work overall pretty well even with 10 bulbs connected in 3 different rooms.If you get the wifi bulbs I don't think there is any option to connect to your google home or alexa. You need the hub if you want to do that.It would take a really long time to actually save money on electricity with the bulbs. These are more fun than money saving, but the app does show how much electricity each bulb has used, and I thought that was a pretty fun addition to the app. My previous bulbs were very hot to the touch, hot enough to burn my fingers. These get warm near the base, but are basically room temperature everywhere on the bulb.

These generally work and look great. However, it doesn't take much for them to lose connection (often during a brief power blip, for instance), and from then on, they're incredibly glitchy unless you delete them and freshly install them. If you have a smart home where a bulb might be part of a number of routines, you'll see the problem: you'll have to delete the old bulb, add the new one, and then update every routine that had the bulb. It's just not worth it. I'd recommend Cync or Phillips instead; I've had better luck with both!

Son las mejores bombillas compatibles con Alexa, la verdad las amo me encanta tenerlas
