Two of them entered the room and I control them through openrgb from the computer to have all the lights synchronized after installing custom firmware on them (the review refers to the factory firmware).
The intensity is very good and they reach 800 lumens, but only in natural white... the warm one is around 600 and the cool one is 700-750 (measurements with a brightness meter). The RGB plays around 400-550 depending on the color.
They connected to an aftermarket access point and haven't disconnected for 3 days (100% uptime). Those who complain about disconnections, etc., should check their garbage network instead of criticizing the bulbs.
Regarding the application: simple for basic settings and has a menu for advanced users who know more and want to get involved. It has basic automation settings and has smart home integrations (Google Home/Alexa, etc.). A huge plus is that it simulates the light of the sun during sunrise and sunset... it may sound silly, but it has helped me a lot to wake up in a good mood as I live in a basement without windows.
We will see durability over time... I will update it for any potential issues.

I have three WIZ RGBW bulbs (one at 1055 lumens and two at 806 lumens) for 4 months now. I also bought a WIZ remote control (for the... little members of the family who do not have a... mobile...). The control has the basic functions for the bulbs (on-off-selection between 4 modes/color of lighting).
- The bulbs are wonderful both in terms of brightness and connection quality with the wifi router and, by extension, with the mobile through their application (I have it on an Android mobile).
- Their lighting colors (selection between 16.7 million custom colors) are quite good in brightness and reproduction of the true color. Especially the cool and white white, it just lacks intensity!
- I did not notice any particular delay in their connection (as soon as I open the application, the bulb "connects" - becomes available in the application in 1-2 seconds at most). The router I have is a factory one from Vodafone, so it is not true that it has issues with factory routers (unless someone has a router with an extremely weak signal - they will also notice it with the connection of their mobile through wifi... low signal, etc.). Note that the switch of each bulb must be on. Then you operate it (turn on-off, etc.) from the mobile-tablet through the application. This applies to all bulbs from different manufacturers.
- The Wiz bulbs have the ability to be programmed to turn on and off on selected days and at any time you want (each one DIFFERENTLY if you want!) through the application (very important for me).
- And now the best part: I can turn on-off-change color-program, etc. through the WIZ application via my mobile with 4G\5G, meaning REMOTELY WITHOUT being at home (without being directly connected to the router's wifi, at home)!!!! Amazing!

I highly recommend them (if something goes wrong, I will come back). Obviously, other companies have similar bulbs with similar capabilities, of course (maybe more or less). I chose this one, I will stick with it since it does what I want with the bulbs :-)
I do not know if they will last and for how long, they seem to be of good quality, but... they are bulbs :-)

I bought this specific lamp mainly to play with the lighting. HOWEVER: I found out that it is much more than just a simple change of lighting because it has:
1) Through the application, you can literally do everything.
2) It works perfectly with Google Assistant, Siri Shortcuts, and Amazon Alexa.
3) From the application, you can create your own light shades and have specific schedules.
4) Variety of programs already from the factory.
5) It shows the lamp's consumption - very good.
6) If you explore the application and IFFT, you can set, for example, to turn on/off the lamp(s) when you are outside/inside the geofence on the map. There are nice websites that explain very well. A good article is this one here: [insert link]
Overall, at first, it may be a bit confusing, even for technologically savvy people, but along the way, you will wonder how you could live without it! Highly recommended if you want to give a breath of freshness and a technological aura to your home, especially at this price of 15.90. I hope I helped

I have 18 Wiz bulbs in my house and I am almost completely satisfied. Very good value for money, especially compared to Philips Hue. They are also made by Philips' parent company, Signify.
They are quite bright (especially the A67 blinds, the Daylight white is superb). Quick response, had no problem connecting the bulbs to the network and haven't experienced any disconnections in the 6 months I've had them.
They have ready-made "scenes" where the bulbs change colors, sometimes slowly and sometimes faster, such as underwater, pastel colors, spring, fireplace, candlelight, etc.
You can create your own scenes with fixed colors in each room.
NEGATIVES:
1. If you have many bulbs, it is good to have a decent router, not the ones provided by the providers. You may experience delays and disconnections. With a good router, their performance is perfect!
2. Apple HomeKit is not supported. However, you can use Siri Shortcuts and leave your guests speechless with a "Hey Siri, cinema lights" command!
3. The scenes you can create are for each individual room. So, if your kitchen and living room are connected and you want to create lighting for both, you will have two separate scenes. However, you can activate both scenes simultaneously with a Siri shortcut.
Overall conclusion: Get them, they are a big change for any home!
