NOVOSTELLA 13W Alexa Smart Light Bulb B22 1300LM (120W Bulb Equivalent), Dimmable LED Bayonet Bulbs RGBCW (RGB+2700-6500K White), WiFi Multicolour Bulb Work with Google (No Hub Required, WiFi 2.4GHz)

(Writing this review after half a day of use or so. I don't normally leave reviews so I will update if necessary.) Finally replaced my nearly-decade old CFL bulb with this, it was definitely an improvement. My main criteria when looking at other bulbs were (in descending order from most important to least): Brightness, the ability to change colour temperature (RGB is a very nice plus too), price, and the ability to easily add it to an OpenHAB setup that I have on a Raspberry Pi.Brightness - To be honest, I wasn't too sure what I was looking for as I didn't have a point of reference to compare my old bulb with, but I was mainly looking for something to light up an entire room that was as bright or brighter as my old bulb. Looking at most other smart bulbs they seemed to be advertising as giving off ~800 lumens and a lot of them were mainly shown off as being used in standing lamps and desk lamps, and a bunch of regular "dumb" bulbs from supermarkets were advertised as ~1200 lumen bulbs, so I thought I'd go higher than that as it's an LED bulb anyway and should use less power.Well this definitely exceeded my expectations. This went in a mid-sized room and at full brightness (and set to the coolest colour temperature) in a pitch black room it lit the room up as if the midday sun was shining through the window. For comparison to my old bulb, when set to a similar colour temperature, you'd just need to set the brightness to ~35-40% to match the old one. +1 for brightnessColour temperature + RGB - I was looking for a bulb that mainly allowed me to change the colour temperature as my old bulb had a rather warm colour and I wanted to change things up. Quite happy with how easy it is to change, as the sliders do a quick job of it. The RGB colours for it are also nice and vibrant (at full saturation though this can also be controlled), and it seems like the Smart Life app allows for the most control when it comes to this. I was also wondering if it was possible to have it constantly cycle through colours and it is, it's Scene 4 in the Smart Life app though I'm not sure if this is doable in other apps (Google Home's controls were somewhat limited). Though after some time of playing around with it, the RGB colours are closer to a gimmick but could've been used for a much better purpose (more on that in point 4).Price - Originally I was gonna pick up one of those TP Link Tapo RGB bulbs for just over half the price of this one, but the 2 or so reviews of it exploding, and other smart bulbs around this price being from seemingly no-name brands (those with barely any mentions online) made me change my mind and pick this one.OpemHAB related stuff - One of the main selling points for this for me was seeing that it was a Tuya bulb, which suggested I would be able to flash it with Tasmota OTA without having to do any soldering. Unfortunately, it seems like the bulb I got had a too new of a firmware to do any OTA flashing, and I'm not sure if it's a YMMV thing or if they'll all be too new. It should still be possible to flash this with soldering but that is not something I'm willing to attempt while the warranty is still valid. I was originally intending to use this and hook it up to a web server and use it to "show" various notifications and stuff when they happen as well as to get out of the Tuya ecosystem, but that will be put on hold while I try to get it working in that way.Overall, good bulb, exceeded my expectations in the more standard aspects but was a bit disappointing in other more niche ones.

I wanted a brighter light for my room, and this is definitely bright! I have dimmed it to as low as it goes and it has a good range of light, it doesn't go super dim but that's a personal preference so I wouldn't worry about some of the reviews saying even at its lowest that it's still very bright, it's fine. In fact, if you wanted proper lower light, simply lower the brightness and change to another colour (like blue) and the room is nicely toned down. Overall, a very good bit of kit that was easily set up and working in minutes.

Works great as the main light in a bedroom, can control brightness and colour from Google home app. The only downside is that I had to create a new SSID on my WiFi router just for the light bulb as it won't connect to an SSID which supports 5GHz. To be fair this is mentioned on the manufacturers web site.

I bought this to replace a £6 no-name bulb, and it's so much better.It was quick and easy to set up and then link to Google, has good brightness, and the colours are great. Both whites are good and you can blend them as well.

These bulbs are the best compared to others on the market and will be sticking to this brand going forward. Super bright and integrate with Alexa without a zigbee hub. The bulbs work well within the Smart Life app and super easy to control.

Perfect and the best I have used, brightness really good and the App is superb..Setup a New Virgin Hub 3 that works with 2.4ghz and 5ghz by going into the Hub Settings splitting the 2.4ghz and 5ghz to 2 different SSID names, you tube videos available and yes it's so simple for you to search your home wifi just put 2.4 at the end of the SSID so it's easy to know which WiFi to connect these devices to lol. Setup with Alexa was a breeze just add the device look for the manufacturer and hey preso all connected. The pairing mode and flashing bulb to identify setup mode just the best.

It's cool white light /day light is bright and equivalent to 100w bulb . Connected with Amazon Alexa & mobile app and works fine. You have option to change light colours. Easy installation.

Bought 3 when I set them up after moving house 2 work great 1 only did white blue and green but no option complain cos I had them well over a month before I unpacked them be sure to test right away to make sure they're not faulty
