+ Inexpensive + On/Off works with Alexa + Default white setting is quite bright
- App is not intuitive at all - Color change is very difficult from the app and doesn't work with Alexa - There is no good way to set different white color temperatures - Once in any other white setting than the default cool, they are very, very dim
The above gives you a good idea of the capabilities of these lights but a little more detail on the white settings:
The app is the only way to change the colour settings. In order to do so, you move a pointer on a wheel to the colour you want, a slider determines the saturation level and also the brightness. I can deal with the HSB setup but I would much prefer either a standard colour circle that is used in the Wink app or numerical RGB settings.
This color selection setup is also used if you want to move from the default white setting which is very much on the cool blue end of the scale. If you want a warm white, you have to tinker with using a yellow hue with low saturation. The problem is, once you do this, the brightness is greatly reduced. These were originally for a bathroom vanity but the inability to get a decent warm white color temperature with acceptable brightness means they are going back in the box.
I bought a bunch of these for use in an event space hoping I could configure them to a few different moods and at the push of a button. If that is what you are after look else where the control app just doesn't have the functionality to have multiple different color looks stored. It also doesn't consistently work when sending out commands via the scenes. The other issue I ran into is they only work with an internet connection if you want to use the groups settings. You can't set them up or control them by groups if the internet is down. So they need a 2.4ghz network connected to the internet to be able to function as a group not just a 2.4ghz network. If your needs differ from mine then they are a fine light bulb for not a lot of money however the promised features can be lacking/not functional.
These bulbs show a lot of promise: +relatively inexpensive +runs over wifi so you are not adding to the congestion of the 2.4 Ghz band with new protocols like Zigbee +cloud-based architecture means that you can control it from outside your home and it integrates easily with Alexa
The bad news is that in real life use the bulb falls short: -Because it only works via the cloud if your Internet is down you can’t control the bulb from your cell phone (even if both devices are on your home LAN which is still working fine.)
-if the bulb loses power for a few hours it may get unprogrammed and you have to start all over as with a new bulb.
There are other annoyances which folks have highlighted (the default white as cold as ice, kind of a dim bulb for 8W) but those are not deal breakers.
I hope the manufacturer keeps improving the product, they have a good proof of concept.
The product is cool. It did everything as advertised. Nice color range. Works well with Alexa My problem is, one bulb has already stopped connecting to the wifi. Im not a "non tech" guy. The bulb is defective. Stopped connecting to wifi completely. I bought these around December and one, of the four, stopped working properly, by Feburary. Any light bulb, let alone a led, should last longer than that. Customer service replied to my email in a timely manner, first asking the model, then my order number. Finally, they told me to refer to the info on the box (as if I kept it). I just want a working light bulb, not a run around.
Less than five months and these are starting to not work. I installed many and now 5 have stopped working over the last few weeks. A couple just don’t turn on at all, two are stuck on and one just blinks periodically. It starts with the blinking. Stupid. They would be really nice if they worked longer.
Bought this in mid-January and it stopped working the first week of March. I've tried numerous times to restart the lightbulb to no avail. It fails to go into the blinking modes that make it able to connect.
In the short time that this bulb did work, it was very convenient and nice to have. I could set it to turn on just before I returned home from work in the evenings, which was very nice for the dark winter evenings. I suffer from migraines and it was really nice to have a bulb I could dim.
The colors are less tunable than advertised. The app offers a slider to increase or decrease the saturation of colors, but that seemed to not work at all. Decreasing saturation changed the color (rather than being a slightly desaturated red it would change to a soft yellow, for example)
When I first got this bulb, I was so happy with it I recommended it to a few friends. I would not recommend now. It's too much money to spend on a bulb that lasted barely a month and a half.
I've noticed that these bulbs have a nasty habit of losing their pairing after about a month - just all of a sudden, you see a bright flash of light, the bulb is in full bright white, and it does NOT responds to calls from Alexa. The ONLY solution I have found to this is to pair the bulb back up with all other smart devices disconnected, with the odd side effect that other bulbs in the network can probably come unpaired in the meantime. I do not know why this is, but I do know that it is stupendously annoying.
The light itself is nice and bright. I can't say how the colors are as I was never able to connect the light, using every single light option in the manual section of the smart life app as well as both EZ mode pairing and the slow blink pairing. I spent hours just staring at this looking at tutorials and reading the instructions hoping I just missed something.
I'm just going to go get the more expensive hue light, but that one is literally plug and play. No switching the light off for 10 seconds and turning it on, off, on, off, and in again in 2 second interval for hours.
The good: while I see a lot of criticism in the reviews about Alexa integration (I don't use Alexa), I have had no issues whatsoever with Google Home integration. I can control the lights with any of the various Google Home devices scattered throughout my house or using the app on my phone. I can change the color from within the app as well. The bad: brightness may leave a lot to be desired. It actually works out well for us because if we set it them "gold" in our bedroom, it's dim enough to not be a nuisance while dealing with our infant son. But if you want any color other than white with any kind of brightness, look elsewhere The ugly: these lights worked okay for a couple of months, but then one of them died completely and another one started flickering random colors and turning itself on and off.
Many people are wrongfully reviewing this saying it ranges from bright white to bright white. That is very wrong. It ranges from very dim yellow to very bright white. You can practically choose from any color and brightness besides Red. Only Bright red works, dim red turns pink/purplish
Update : I've noticed that unless the light bulb is off, 100% on, or Max brightness, it makes a loud buzzing sound. It is very annoying. Apparently it is very common with these light bulbs according to reviews. Just wish I knew about that before buying it because I am the type of person that this sound gives headaches and bothers me. Also, one of the few time's I remembered to turn the light off at night by the app, it randomly turned itself on in the morning. Not sure if it is worth keeping and being woken up randomly throughout the bulbs life
