Very bright whites, weak colors (that's why 4 stars). Good app, installation and connectivity with Google home. Its whites are good enough to support main room lighting.

There was a difficulty until it synchronized with the network, but everything is fine.
If you want it for the colors, it's better not to choose it because I consider that compared to the white, which can illuminate even a large living room, it is of low intensity. If you want it for the colors as a "complement" in the space, for example, not just the light of the TV or computer, it can be useful.
In terms of cost, with the same amount of money, you can get a 3-meter LED strip and have colors.

When it comes to white, there is no discussion, it performs well whether it's warm white, natural, or cool white.
The application has several useful functions, some of which may be unnecessary for others.

It can even be used as a night light by selecting a color (usually yellow or orange), and if it is still annoying, the color intensity can be reduced. Always based on the colors because even at 1%, it illuminates a lot in white.
It retains the settings even after a power outage or even if you need to move it to another room.

Also, through the application, you can use it in the yard where it will turn on and off according to the times you set using the timer.

A negative aspect I consider is that its use is exclusive through the application. What do I mean? If you have turned it off from the application after the switch on the wall, it does not work, so if you don't have your phone near you to light up the room.
As you can understand, if you turn it off from the application and then search for your phone in the room, you will need a flashlight.

Amazing! It can work with very bright or very dim light! Its application is quite good, especially after the upgrade... I highly recommend it without hesitation!

Very powerful bulb at 2700K, it illuminates a normal room exceptionally well. Of course, it doesn't only have 2700K, I just find the cool lighting a bit annoying, but the brightness is still abundant there.
The application is a bit slow, but once you learn it or connect it to Google Assistant, you don't need to use it much.
The application has some preset settings, e.g. "read," "relax," etc., but also the option to change colors, something like "party mode."
The colors could be a bit brighter, the truth is that they don't reach the brightness of the bulb when it is white in any case, but it is acceptable.
The intensity decreases through the application, but I would like it to decrease a little more than the minimum it reaches so that it can function somewhat like a night light.
Very important detail: it does not work on 5GHz WiFi, only on 2.4GHz.
Finally, from Germany, you can find a package with three bulbs for 21 euros. I don't know what profit the suppliers or merchants make here, but the cost is unacceptably high, and the only reason I don't give it five stars is because of this!
It is one of the most cost-effective bulbs to buy considering its brightness. I am seriously considering buying more of the same, but definitely not from Greece with these prices!
