Disconnected randomly from wifi and constantly blinking like crazy, while I was away for several days and couldn't do anything through the app. Couldn't even close it. Going for an immediate replacement with a different brand. I do not recommend it.

Excellent lamp, many vibrant colors to choose from, works seamlessly with Alexa. Gives a very nice color to the room. It also has durability as I have had it for over a year and it still works like the first day. I will buy more.

As a lamp in warm/white light, it is excellent. The RGB options are relatively weak and without a wide range of choices, but if used as a background light with RGB, it is good.

Easy installation on mobile and equally easy connection to Home Assistant (unlike other brands I have tried, such as Xiaomi or Sonoff).

As a lamp, it is great, offering many beautiful intensity and lighting functions.
However, I had a big issue with connecting it to the controlling application, it couldn't find it no matter what.
In the end, after a lot of trouble, I managed to make it work smoothly since then.

Really avoid these specific V tac bulbs ... they disconnect with the slightest touch, they constantly need to be adjusted from the beginning, and after 5 months I can't adjust any of them! It happened suddenly.. Unfortunately, a friend recommended them to me and I trusted him without looking at some of the recent reviews.. As I found out, the company now has factories in Romania, and it's possible that all V tac bulbs that come to Greece are from there! I simply don't believe it's worth the trouble, choose another brand instead!

I have it in a lamp in the bedroom for over a year. It works flawlessly without ever losing its connection. The light it produces is satisfactory both in white and in color.

Very good choice! You can adjust the intensity and temperature of the light, choose from the many available shades, select a color-changing pattern, or use it as a light therapy (I tried it through the mobile app).
The only difficulty I encountered was at the beginning, in synchronizing it with the device.
Try it, it's worth its money!

While I have other products of the same brand that work normally, this specific one turns on whenever it wants and if I hurry to turn it off and on again, it starts blinking and I have to reconnect it with the application. Also, it disconnects on its own and sometimes the application doesn't recognize it. Other times, it turns on but with low brightness, and other times it's very bright without me making any changes through the application. Overall, it's all over the place and I'm close to going crazy. Despite all this, it has a very strong light.

Very bright and easy to use. Works very well with google assistant. If you want to hang it, you should know that it is heavier than regular bulbs, but this is expected. The colors it has are amazing, the blue is a bit low in intensity but it is known that it is the most difficult color.

The lamp lasted about 3 months. Initially, it worked well, with a slight delay in changing colors and without any disconnections. Suddenly, one day it started flashing constantly and wouldn't respond to commands. I tried to troubleshoot it extensively, but unfortunately, it wouldn't accept a reset or anything. The warranty from the manufacturer saved me.

Apart from the fact that every 2-3 days it would lose the WiFi connection, when it did lose it, it would stop working properly and blink until I set it up again.

I will only write the negative aspect to inform potential buyers.
In the white spectrum, the minimum brightness that you can adjust is quite high.
To use it as a night light, we set it to the RGB scale, where the minimum brightness is satisfactory.
However, we noticed the following problem:
We have programmed it to turn on and off automatically.
While it turns on normally, when it's time to turn off, instead of turning off, it simply switches from RGB colors to white. Moreover, the application shows it as closed while it is in white light.

I have had it for about a month now. It has never crashed. Excellent collaboration with Google Assistant. Honest for its cost.

Strong light in all shades of white,
It illuminates more than a regular lamp!!
Additionally, it has light effects based on music if you choose it (which was not mentioned in the description).
The only negative thing, and that's why I give it 4 stars, is that during color transitions it does something like a sudden flash and doesn't go smoothly.. but it's not so annoying..

What you pay for, of course, you get the RGB colors equally well, but with less brightness, the bulb sometimes disconnects and you have to reconnect it with your phone.

It is good to look at the instructions.
Everything is perfect, it connects easily and quickly without any problem!

Very good lamp for its price. I was able to connect it the day before yesterday after having it in my possession for 5 months. Obviously, they updated the v tac light application. Very satisfied

Unfortunately, the batch is defective in terms of RGB. When changing colors, in blue and green, and when the brightness is below 70%, it throws white at regular intervals. And the replacement bulb they sent me was also defective - as my friends who bought the exact same bulb confirmed to me, they all had this problem.

However,
For its price, it is very good.
Fast and easy connection with the app. The colors have nice shades, and the white is quite bright. The app is user-friendly, but it doesn't offer many options for preset programs, nor can you save your own.

Very satisfied overall. Strong with nice shades. The music selection is awesome. For its price, it is unbeatable.

Excellent cost/performance choice for its price. Fully compatible with v-tac software, easy to install and use, it delivers on its promises.

Overall, a powerful bulb with the option of selecting the temperature of white light, but weak in colors. Only suitable for effects

I bought 3 of these bulbs, I have been using them for 5 days now. I haven't had to reconnect any of them, and I have turned them off and on several times from the switch (it takes a little while to get used to it after years of flickering from a switch).

There are (many) positives and negatives.

On the positive side:
- Very bright in white, at all temperatures, even at low intensity.
- Immediate response to commands, either from the app or from Google Home.
- You can set up automated commands based on time, etc.
- If you are a developer, you can do custom integration with the Tuya IOT API (free for basic use).
- Easy connection with the app and with Google Home.

On the negative side:
- The colors are not bright, but I haven't seen any bulb (especially in this budget range) that has strong lights in colors.
- The instruction manual is outdated. The app has changed, so it confuses a little (or a lot).

Honest lamp, the white is quite bright (~1000 Lumen) and it also gets warm, the colors are less bright (expected), the connection with the app is a bit tricky but manageable, I suggest doing it with auto scan.

Negatives:
- If you turn off the switch, it may disconnect from the app and you will have to reconnect it.
- I don't know if mine is defective, and it's not a big issue, but when I switch between colors and brightness, especially at low brightness levels, the white light of the lamp momentarily activates like a flash. It's a bit annoying while you're trying to find the brightness and color you want, but once you find it and leave it there, it won't do these flashes (that was missing)

Very easy connection with the V-Tac Smart Light application. I operate it flawlessly with the ALEXA application for voice commands. Very good brightness in white. Less bright in RGB (colors). Value for money

Whatever I say is not enough. The bulb is impeccable, easy synchronization from the Android application, and endless possibilities in lighting settings. I use it in my office, where it has satisfactory brightness. The application, besides colors and intensity, also provides the ability to program the bulb to turn on and off with a timer or a weekly schedule.

Very good.... a little difficult to connect and the RGB colors could be brighter, but in the end everything is ok !!!

First purchase for a living room portable lamp.
Easy connection with V-TAC Smart Light from the app store.
I had difficulty connecting it to Google Home because during setup, the VTAC Smart Light service did not accept passwords with special characters.

I have been using this lamp for a week and I am completely satisfied. The connection is very fast and the application is easy to use. The brightness of the white light and the ability to customize it are amazing. The colors do not reach the brightness of the white light, but this is not a negative thing. When I turn on the light from the switch, it maintains the settings I have made from the application. It also easily connects to Google Assistant. For its price and overall capabilities, I highly recommend it!
