TUO Circadian Sunrise Simulation Smart LED Light Bulb. E26 Base - WiFi and App Controlled. (Generation 2.0)

I’ve been using this lightbulb for a few years now and just got a second one. I’m super impressed. It was extremely easy to connect to the internet and set up through the app. Everything paired on the first try. Once connected, I was able to easily create a personal circadian lighting plan right in the app. It automatically adjusts the brightness and color temperature throughout the day, and honestly, I just “set it and forget it.” It’s been great for helping me feel more awake in the morning and relaxed in the evening without having to think about it. I travel a lot across timezones so it makes coming home and readjusting my body clock that much easier. I did notice a tiny flicker before it was connected, but that completely went away once it was running my own setup. Now the light is smooth and natural. Overall, this bulb does exactly what it says - smart, wellness-based lighting made easy. Highly recommend!

It's really is a great idea to have a bulb that automatically turns on in the morning at a high Kelvin rating to simulate a sunrise, then turns on again at a lower Kelvin rating at night to simulate a sunset. Too bad the company hasn't figured out how to do this yet. I went through 2 bulbs, but ended up returning both of them. Maybe in a year I'll try again. The first bulb wouldn't change to the different Kelvin settings, it was always the same color (about 3500k) It did turn on and off at the correct times, but it also randomly turned on and off for about 10 seconds a couple times throughout the day and night. The second bulb actually worked perfectly, turning on and off at the correct times, with different brightness in the morning vs. the evening. After 3 days is use, the bulb lost the internet connection, and wouldn't work again. I couldn't connect to it through the app, and it stopped turning on and off. If i manually turned it on, it was the wrong color since it wasn't connected to the app. Some issues are in the app, not the bulb. For example, there are 4 different modes that the app defines based on the wake time and sleep time you enter: Super Wake, Wake, Active and Calm. In theory, if you manually turn the light on anytime of the day, it should be set to the correct brightness based on your circadian rhythm. (brightest in morning, reddish colored at night, and somewhere in the middle during Active times.) Super Wake should be the brightest (which is 5000K for this bulb), but the highest setting for both Super Wake and Wake is 3500K. The highest available setting for Active and Calm is 5000K, which is backwards. The only way to fix this is to manually change the mode from Super Wake to Calm, AFTER the light turns on every morning. (you can set the Calm to 5000K beforehand). This has to be done every day in order to get the 5000k morning light...which defeats the purpose of having an automatic light. While I'm waiting for them to fix these bugs, I'm going to set up a 5000K and a 2300K bulb next to my bed, both on their own timers.

I like the idea but for the cost of the product and its basic functions it’s pretty buggy. For example, it’s not an uncommon occurrence for the light to automatically turn on at random times. This quite annoying when it’s the middle of the night. When it works correctly though, it’s quite nice and crests for a much more peaceful wake up. Lastly, I wish it would slowly fade in a bit more in the morning rather than just turning on. So would I buy it again? Probably not.

I love this light, it's been a game changer for my energy levels. The frustration comes with the very poorly designed app and the lack of any offline, Matter, or HomeKit support. That being said, I'd buy another one if I lost this one.

I’ve been using the bulbs since I heard about them in one of the Huberman podcasts. It helps with waking up in the morning and staying active especially after lunch time which used to be really hard to stay active. The kids use them in their rooms and they have to wake up early for school but have been pretty consistent since we started using the bulbs. I think the fade setting at night helps them wind them down and wake mode wake them up naturally compared to conventional lights. Highly recommend!

This is my first time ever writing a product review. This bulb is so cool, it has the ability to turn all sorts of different colors as a bonus and is app controlled and time scheduled to wake me up at a certain time every day. Multiple modes for waking up, vs calming down at night. The science behind it is there, I can’t wait to see the positive benefits moving forward

Died In 7 months. I've have led bulbs though out my house, in use for over 10 years. This is the only led bulb to fail so quickly. This is junk.

I have had 3 of these bulbs and love the concept. Unfortunately all 3 failed in less than a year. Great idea with flawed quality control. I should add their customer service is awesome - hoping bulb #4 is too! Update: free replacement bulb working well.
