Sengled Zigbee Smart Bulbs, Tunable White 2700K~6500K, Hub Required, Dimmable via Wall Switch, Works with SmartThings and Echo Plus with Built-in Hub, Daylight A19 E26, Voice & APP Control, 2 Pack

I started getting more into locally controlled devices(specifically zigbee). These bulbs are sufficiently bright and connect to my Home Assistant Sonoff Zigbee coordinator with no issue. They are as fast as zigbee allows them to be (which is pretty responsive). A good option for those who don't want to overpay for Philips hue and want a cct bulb. One caveat is they are large so might not fit all light fixtures.

I just setup one of the bulbs I got. I'm fairly happy with it. Nice clear light, and the bulb responds to commands quickly. Reasonable price.The dimming could be better. I'd like it to have a lower range.I'd prefer if these bulbs operated on z-wave instead of ZigBee, but they work with my Hubitat Hub nonetheless.

These are easy to set up smart bulbs - I hooked them up to a Smartthings hub. Just needed to tell the hub that I was connecting a Sengled light (you do this via the Smartthings app), and then follow the instructions (you can use the regular Sengled light setting, you don't have to use the Zigbee setting -- that will tell you to just use the regular setting). The light flashes and is connected. Easy to control the light brightness and coolness of the light (these are tunable white lights). Everything is great. Time will tell how long they last (check back with me in 15-20 years), but I am satisfied at this point!

I'm currently using these bulbs with a Sonoff 3.0 Zigbee USB stick and Home Assistant. Installation was straightforward. It was easy to put it into pairing mode (put the bulb in a fixture that has a switch and turn on/off 10 times until it starts blinking), and it was detected by zigbee2mqtt instantly. Changing brightness and temperatures were instantaneous.There are a few tradeoffs for its cheap price though:1. The bulbs are very warm colored. At the coolest temperature and highest brightness, it still has this warm orange-ish white, rather than cool blue-ish white.2. You can't set power on state, so if you have a power outage and go to sleep. The lights might pop back on at 2am when you have power and wake you up.I'll continue using them for now but will definitely get some discounted Hue bulbs next time to eliminate these cons.

Wow! These are heavy....for a lightbulb. And thats not a bad thing. They seem built really well. Paired with my zigbee stick in literally 2 seconds.Only potential downside, as others have mentioned, is the top of the bulb is clear. With the light at 100%, if you have a direct view of the top of the bulb (ie, its not behind a shade), it is VERY bright and distracting. A frosted top would help this.

These do not work with any service unless you sign up for their fancy account. Where they gain the power to control the devices as they see fit.

These are quite the bulbs for the price. If you get them on sale, a 4 pack costs $20. That’s really cheap for smart bulbs, not to mention that these are tunable. The brightness is on par with other bulbs I have. It works well with my Sengled door contact sensor. The value for the money is about as good as it gets.

ok

The media could not be loaded. Setup was fairly simple. It was harder then I expected to put it into pairing mode, but this is actually a benefit for me because my old lights would reset by accident all the time.I connected it to my Home Assistant server through Z2MQTT using a USB zigbee radio, and it's working well. It has to be pretty close to pair, but once that's done it works from across my house with no repeaters.Very heafty bulb. I've seen complaints about this but it does not negatively effect my use. If anyone it makes me feel more secure about it's build quality, so I'm quite happy with that.Responds instantly to commands through home assistant. You can even tell it at what speed to fade to the new light (instant, fade, slow fade). Home assistant seems to think it can change its color temperature much farther than it actually can, but that's probably an integration issue rather than a problem with the bulb. The range of color temperature it can show is satisfactory; enough to give a cool daylight effect, or a warm candlelight one.Overall, I would recommend.

Una muy buena opción para comenzar con las luces inteligentes. La bombilla es de material de muy buena calidad y además la estética es un apartado muy bueno.Altamente recomendados.

These are perfect for my house smart ecosystem,The color features works great gives me option to go with 4000k of my choice.Easy setup with my SmartThing hub, and setting up timer for them

Just got two of these. One won't enter pairing mode and the other has no wifi connectivity. The one that tries to pair gets very hot and I am reluctant to use it. Ended up with one expensive conventional led bulb.

... also, Doesn' t act as Zigbee router/relay, (ZigBee devices that are permanently powered - such as lightbulbs, smart sockets, basically anything that is connected to mains power - generally tend to act like extenders.)They were easy to pair on my Zigbee environment though.I will either send them back or they will end in the garage or the porch outside.
