    Very happy with this product. Trivial to set up as it comes with tasmota. Bought two and would buy again.

    These are excellent bulbs. Full range of color and instantaneous response in Home Assistant over MQTT. I bought three to replace Wyze bulbs in a few lamps that I had but now I’m planning on outfitting our entire house once we move in a few months.

    Excellent bulb! Looking forward to replacing all my standard bulbs!

    Bulb was easy to add to my WiFi network and quickly integrated with Home Assistant with MQTT auto discovery. Both response time and color range is *significantly* better than my Philips Hue bulbs (e.g. Hue’s greens are terrible.)

    These are my new go-to for smart bulbs around the house. 10/10 will recommend any time I’m asked about lighting, definitely getting more of these.

    Recommended! I have had 6 of these for about a month, and I’m liking them.

    Some thoughts:

    UI: It is very easy to get the bulb set up and logged into the wifi, the Tasmota web interface is super easy to use, and the Tasmota user documentation is comprehensive and easy to understand. I now have these connected to a Raspberry Pi 4 on my LAN running Home Assistant and MQTT. Response time from phone-tap-to-lighting-change (via HA-MQTT) usually “feels” instant on my wifi, occasionally seeing perceptible delay but still basically under one second to update.

    Subjective brightness: These are best for illuminating an accent wall, lighting up a dim quiet corner of a room, a bedside reading light, or a dimmable / adjustable nightlight.
    At max brightness, these are NOT going to turn night into day or compete with the light from a window or blind you or surprise anyone. It’s just going to be the difference between “pitch black” and “there is enough light in the room to read a book comfortably if you are near the lamp.”

    The internet says these 1000 Lumen bulbs are very roughly “equivalent” to a ~68 watt incandescent bulb, if anyone still thinks in those terms like I do.

    Rated for Indoor use only, Not for use in damp locations, Not for use in enclosed or recessed luminaries (e.g. dome or can lights), and keep away from dust or heat sources.
    The base of the bulb gets hot-to-the-touch during constant use. It’s cool enough to be able to unscrew it by hand using the round end, but the pointy-base will be hot until it cools down.

    These seem best for making “regular” table lamps and tall lamps just a bit “smarter” and more convenient to use. I find they are perfect for a natural tinkerer to try out what this dang “smart home” thing is.

    Advice for the end user on backups: These lights come preset out-of-the-box, so use the “Backup Configuration” button once you get the lightbulb working, and keep the backup of the configuration safe. IF at some point you find you need to reset the lightbulb using the “5-or-more short power cycles” method, that nukes the Tasmota mapping of “which-color-mode-is-which” — like, literally Tasmota will think that “off” is green and red is blue or something. It was easy to fix by downloading the configuration from an existing lightbulb and uploading to the freshly reset lightbulb, but that assumes you have at least one working lightbulb, so a backup config seems wise.

    Downside: I have exactly one lightbulb that occasionally will stop responding after ~2 weeks. Moving the lightbulb to a different socket usually fixed the issue. I do not yet suspect the lightbulb is bad; rather I suspect either the lamp base is providing flaky power or its awkward location causing occasional wifi drop-outs. I have not isolated the issue yet, still investigating, and again, all the rest of the lights work fine. Currently trying out an “auto-reconnect if wifi disconnects” Tasmota rule, we’ll see if that fixes this sporatic issue.

    I’ve gone through three of these now. Two of them started strobing at about the 9 month mark (think high speed pwm blinking), and of the two replacements I got, one of them just died a month after installing it.

    Amazing bulbs, really fast when integrated with homeassistant and colors are vibrant. Will buy more when available.
