3Stone Smart Light Bulbs, 16W 1600 Lumens WiFi LED Color Changing A21 Bulb 100W Equivalent Dimmable 2700K-6500K RGBCW, Tunable White Works with Alexa, Google Home 2.4Ghz Only, No Hub Required 4 Pack

Works great in Android using Smartlife.

I have about 80% of the house configured with smart bulbs, because I wanted ease of control with integration with Alexa. 100% disclosure here, I don't care about the app for the smartbulbs, as soon as I get it connected and added to Alexa, I don't use the app ever again. However, the app is good, easy to use and quick to add a lot of bulbs.A couple of items to note.1. These bulbs are on the bigger side. They work fine in lamps and most overhead fixtures, but anything with a tight space that only allows for normal size bulbs, these are not going to work there.2. These are the brightest smart bulbs I have had yet. If this is the selling point for you, you just found the ones you want.One really non-quantifiable thing I can note about these. I have other bulbs made by Gosund and these bulbs seem to turn on and off faster than the gosund's. Your mileage may vary. They just seem more responsive.

They are no brighter than my Wyze 900 Lumen bulbs. So back to looking for brighter bulbs.

Purchased 4 of the bulbs and use with an android app. I programmed the bulbs from my android phone (Moto G Stylus. I program to come on at sunset and go off at sunrise. In the last 2 months those timeframes have changed considerably but settings are perfect and adjusted for your area automatically. Great price and I am VERY happy so far...

Maybe you will see this, maybe you won't! Go go sensitivity filter!Last update:Contacted seller about these junk bulbs. I have 17 that are trash, including 4 they replaced 6 weeks ago. They offered another 4 replacement bulbs. I declined. I contacted amazon because I am outside of the 30 day return window. Amazon transferred me to a specialist who was able to tell me that they were outside of the 30 day return window. Super...? Thanks...? I needed to talk to 2 different people for what reason again?If you get the chance to read this - the super short version is that these have a life span of 60 days - not the 5 years they "should" have. They are trash and shouldn't be purchased by anyone who cares even a little.Note: The seller has stopped selling under the link this was originally posted under, and started selling under this one. Presumably to get away from the increasing number of bad reviews as time goes on. But hey! They did lower the prices from $15 for 1 and $41 for 4, so there is that! The original product link (and my original review) can be found here:https://smile.amazon.com/gp/product/B07HG199VX/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1Update: 83 days since first order.So here I am, 83 days since ordering my first bulb. When I purchased them, and used them for a while I thought they were fantastic, as you can see below in my original 5 star review. However, in the period of time since I wrote this review, the quality of these bulbs has become painfully apparent.All told, I currently have 16 of these bulbs in my house. At any given time, anywhere between 2 and 5 of these bulbs stops responding for days on end. As of this writing, I have 4 bulbs that I can do nothing with besides turn on and off with a light switch. I have 2 bulbs that are entirely dead - they won't power on with a switch, they cannot be reset, nothing. They are simply dead.Originally, I was working with the seller after exhausting all of the various methods you are supposed to do when having issues with these bulbs, but I have completely given up on that. Nothing like sending a message explaining that you have done steps 1-12 on every bulb and now need a replacement, only to have a message sent back asking if you have tried steps 2, 4 and 7. Going through the app for support is even more idiotic as the people who support the app do NOT understand phrases like "I have tried everything you suggest and the bulb will not power on so there is no way to reset it". They will ask you several times if you have tried resetting the bulb. It got to the point with the app support that I had to inquire if they were being intentionally frustrating to get rid of me because I literally could not make it any more clear that the bulb was 100% broken.Now to keep this review 100% honest, I no longer know for sure how long I have had each of these bulbs, but I know it cannot be more than 83 days, as that was when I placed my first order for a single "test" bulb. However, I know that I have replaced 4 for sure in the last 55 days because I ordered a replacement 4 pack from Amazon to replace the bulbs that were beyond redemption, and 1 within the last 70 days because the seller sent me one to replace a bulb that died early on. This means that of the 17 bulbs I have ordered (and the 5 replacements) over the past 83 days, 6 are complete failures and due to the randomness of which bulbs stop responding, I can say for certain that I have never had issues with exactly 2 of the 22 bulbs. That's some fantastically bad numbers (about 9% of the bulbs you will get will still be fully functional 3 months after you order them), and had I been made aware of this when I was shopping for smart bulbs there is no way in heck I would have bought these.I am now just waiting for bulbs to completely die, while I shuffle misbehaving bulbs into areas where it just doesn't matter if I can't control them with anything but a light switch - though I am running out of places to stuff them at this point.Hopefully you are reading this review and saving yourself the frustration of dealing with these bulbs. I am out $191, but you don't have to be.*****************************************************I was skeptical at first. My brother in law is a huge fan of Hue bulbs and tried very hard to talk me into getting those. After checking how much it would be to get everything I wanted, I decided that maybe I should look at some off brands. I started with a single bulb. I wanted to check it out and see if they were worth it. They definitely are!The interface is easy to use, set up, and there's no pesky extra steps you have to go through to get Alexa to recognize your scenes (like other smart devices). I use these bulbs constantly. I have a bedtime scene that turns lights on and off then dims them in stages so when I lie down in bed all of the lights are off 20-30 seconds later. No fuss, no muss.I have a morning routine that turns the lights on really dim then brings up the brightness to "encourage" me to get out of bed :) I even have Alexa turning on and off lights as I leave or come home. I never come home to a pitch black apartment, and I never worry about if I left the lights on all day while I am gone.I have replaced all but 1 bulb in my apartment with these, and I would recommend them to anyone looking for a quality bulb at a fraction of the price.

Love these bulbs. BIG problem was 1 of the 4 bulbs quit working 2 weeks after the return time frame… bought in September, burnt out in November bulbs are supposed to work 250,000 hours. This one burnt out after about 270 hours… I am unable to get to a place for a replacement or a refund. Very disappointed

Very great product.

The media could not be loaded.  I purchased the Smart LED Light Bulb to use with my nightstand.It came very well packaged in a hard plastic, which itself is inside a box. It is practically impossible to break it.Installing it was easy and took less than 30 seconds. Turn on the light bulb, install the application and connect the two with the push of a button.Depending on my mood/activity, I like to have a brighter yellow light for night reading (before going to sleep), wake up with a bright white light, or a colorful light if I am watching TV/iPad, etc... A regular light simply does not accomplish all of that, but the Smart LED Light Bulb does.The application is very easy to use and is intuitive. It even has an "alarm" that turns the light on in the morning.I am a happy customer.

Mismas funciones y calidad que marcas más reconocidas pero a un mucho mejor precio. Además la cantidad de lúmenes son mayores que lo que ofrece la media en el mercado. 100% compatibles con los sistemas más pupulares. Muy recomendable.
