THIRDREALITY Zigbee Smart Color Bulb ZL1 4Pack,Compatible with Home Assistant(ZHA&Z2M), SmartThings,Aeotec,Homey,Hubitat or Echo Devices With Built-in Hub,A19 RGBCW Bulb,2700K-6500K Tunable,800 Lumens

Best LED A19 bulbs I've used. These bulbs pair faster than you can name them, they respond instantly, they don't bounce due to state latency on `turn_off`, they work perfectly with Home Assistant ZHA or Z2M, they do an excellent job in their Zigbee router role, and they make beautiful light. They've rescued our fancy lighting from NanoLeaf-Matter-Thread failures and made life simpler. I can't rate bulb lifespan/durability yet, but many Third Reality smart plugs and several soil, T/H, and other sensors have worked perfectly in my home over a long period and 3R's support for real local control stands out among smart home device makers.

Bought these bulbs to replace Sengled bulbs. Sengled has been having ongoing server issues and some of them stopped working with Alexa. These bulbs seem good. Connectivity was spot on. Easy. Brightness is good. I didn't get them for the colors so I can't rate that. Good value.

These work great as zigbee routers, but the LED colors are not the best. Feel a little dim and washed out.

These are the best smart lights you can buy, especially for the price. These lights are solid RGB Zigbee bulbs, act as Zigbee repeaters to improve your mesh network, are bright, have decent colors, AND are cheaper than any other Zigbee bulbs you can get. Seriously, these are an incredible value, less expensive than most single-color dimmable smart bulbs.I am using them with Home Assistant via ZHA and a Zigbee dongle. ThirdReality is a Works With Home Assistant partner, and these bulbs work perfectly with Home Assistant. They got a firmware update within the first day which went off without a hitch.Whites are good with a range from 2000 Kelvin (candlelight) to about 6500 Kelvin (cool daylight). Color reproduction is fairly good with bright, saturated colors; only the pure green seems a little less saturated than some other bulbs, but otherwise they're great: red, blue, magenta, yellow, and most colors in between all look nice and saturated.If you use Home Assistant, don't hesitate; buy these bulbs! They're an incredible value from a company that cares and is actively supporting Home Assistant. You can't go wrong!

Good bulbs, all the colors, works directly with home assistant over zigbee so it's not clogging up wifi and creating weak points in network security

Pros: Inexpensive. Bright. Allows dimming to low levels. Reasonable color rendering in white (CT) mode.Cons: As others have said, the RGB colors do not render well and are not well calibrated. The different colors of white light look reasonable but these are not well calibrated either; for example when I set CT to 5000K, the bulb puts out 3800K light. Bulb is very bright at 75% level but doesn't get much brighter at 100%.

These bulbs seamlessly connected to my SmartThings hub, making the setup process incredibly smooth. Pairing them was straightforward and hassle-free, as they integrated with the hub almost instantly. Once connected, they performed exactly as I had hoped, delivering reliable functionality without any glitches or complicated adjustments.I was impressed by how intuitive the process was, even for someone who might not be tech-savvy. The bulbs responded perfectly to commands from the app, allowing me to customize settings such as brightness levels and scheduling with ease. Their compatibility with SmartThings means I can conveniently control them alongside my other smart devices, creating a cohesive and efficient system for managing my home. Overall, these bulbs exceeded my expectations with their simplicity and dependability, adding a significant level of convenience to my setup.

I have had no issues with other Third Reality Zigbee products, but this bulb will not even start the Zigbee interview. It cycles through colors to show that it is in pairing mode, but it never actually pairs. (I'm using ZHA.) I've tried multiple times, varying the order. (Sometimes I turned the bulb on first. Other times I started the pairing process with Home Assistant first.)
