      Very Innovative Product


      Installation: -As promised this product is extremely easy to install using the ilumi app. Unlike other household smart products, the discovery of new devices does not require you to change any wifi settings (such as connect directly to new device directly then switch back to your home network) since the connection is bluetooth. App immediately discovered bulb and I was changing brightness and color in seconds in the intuitive app interface. Features: -I am using the A19 in a living room table lamp, replacing a CFL 3 way bulb. The brightness levels are very impressive!. Even though only a 60W equivalent, I have found that in doing a side by side comparison with a 100W equivalent (both behind same lamp shade), I could not find a difference. -Color Changing - The ability to change the bulb to virtually any color came in handy immediately as I was able to slightly vary the color from a pure white to a "soft white" to match other lamps I had in the area. (only until go and purchase ilumi bulbs for those lamps too) -Music Sync - Very neat feature to use when friends are over. The app will play through the music on your phone (or you can create a playlist) and have the bulb(s) dance along to the tracks in a variety of styles. One of my favorite features. -The Torch feature also has been handy. It allows me to leave the lamp switch on and the bulb will power down after I leave the house with my phone. In the same sense, it will power on when I return. I have mine set to always behave this way but you are able to define a schedule for when this feature is enabled. Overall, I am very satisfied with this product. At a low price point AND without the need to worry about communication hubs and extra hardware, these are a solid choice to replace bulbs in my home. The best part is that you can install them in any existing bulb application in your home and use them with a light switch, just as you would your existing bulbs, but then control them with your app at the touch of a button. I would recommend this product and believe that it is the way to go to easily add lighting control to your home at a great price!

      Wish It Consistently Worked


      It pains me to have to write this review - this is a product I've been waiting a long time for (supported the product on Kickstarter) and finally I've got my Ilumi! Unfortunately, I have not had a consistent experience with the bulb/app. Pros: - Colors look great - App is easy to understand, really like the "experiences" function to help sort out what you want the bulb to do in theory - Bulb seems very sturdy and like it will last Cons: - Dependence on Bluetooth. The bulb seems to need to consistently be connected to Bluetooth, and if there's any sort of interruption, everything you have scheduled ends up not happening. I have an iPhone 6 Plus and I've noticed that while you can always have your Bluetooth on, it can't always be connected to Bluetooth devices. -Inconsistency. I'm a tech-savvy person and even I'm having difficulty understanding why sometimes my scheduled "experiences" don't happen, and other times they do happen. For example, I have a scheduled "experience" set to have the light come on at 5:30pm. When I get home, I expect the light to be on. Sadly, I come home on more nights with the light failing to be on than it actually working. Overall, I think they have a lot of improving to do with the app that is required to use this bulb. Connectivity and consistency seem to be key issues here. Really great idea but less than good execution. I would not purchase another bulb, nor would I recommend this until I see better consistency with the bulb doing what it's supposed to do.

      Lazy? Or just love color versatile bulbs?


      These light bulbs are creative and amazing for the lazy man or woman in you. Can you say turn the lights out from bed with Bluetooth? Yea, it's just as sweet as it sounds. Or maybe your babe doesn't want the light off and you kind of are spent and would really prefer them off.... did I mention you can just change the color to literally any pleasing color you can think of.. and maybe sneak that thing slowly down on the brightness and hope they don't notice. So, one perk, I'm kind of relieved to find out, is how you can set your lights up to come on and off at planned sporadic times to gives burglars the false impression you're at home chilling when you go out of town this holiday season. Just don't leave the ilumi boxes in the trash, because if they're smart robbers, they'll notice that stuff and have you figured out. Ok, that's probably not an issue but I digress. If you get hooked on these guys like I did and wish every lightbulb in your house was one of these, note: you can create an unlimited number of 'groups' which are custom settings you've preprogrammed for your bulbs. So maybe you have a setting that turns your video game room into a chill room with grippy colors and not too bright. Obviously you're 'entertaining' setting will differ. Did I mention you can have your little psychic ilumis track where you walk around in your house (with your phone) and turn lights on before you and off behind. Did I mention these are great if you're lazy??

      Disappointed by Illumi

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      This is a good idea, but I was disappointed by Illumi. Most of the presets modes are just senseless color changes. The mode that mimics candlelight flicker is the only one I thought might be useful. The packaging and literature give the impression that the lights can set to music. However, the light does not sync or react to sound. The result is that there is music playing and lights are set to one of the preset or user defined modes, but they have nothing to do with each other. The app has a version 1 and a version 2. The user is required to start with version one in order to install a firmware upgrade for the bulbs before the version 2 app will recognize them. During the firmware update the app crashed and the bulb was left in limbo. There is no real way to correct this efficiently. After 2 days of trying to re-install the original firmware and hard reset the bulb I managed to correct the problem. Once the bulb was working I was able to see and experience what a complete let down this product is. I give it two stars only because you can actually turn the bulb on and off as well as modify the color and brightness. After more research, I am inclined to check out the Phillips Hue system. It has the added feature of a hub to help manage the bulbs you connect. It seems the Phillips Hue lights will actually respond and react to sounds if the user wants them to.

      Good Bulb, Terrible App

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I'm torn because it's a really good light bulb but the app is a mess. I use this thing as a light for my Aquarium and it worked way better than I could have ever expected. my plants grew really well and I could even setup a sunrise and sunset with various different color configurations throughout the day. But... The app is a tremendous pile of unresponsive, unintuitive garbage. It's very slow to apply changes so any time you try to adjust the colors expect to make an event out of it and grab yourself some snacks. They have 2 versions of the same app on the Android store. Both versions are terrible for different reasons. The older version is more straightforward for setting up light automation but lacks some features/modes, while the newest version adds more features/modes but it is incredibly frustrating to navigate through. Both versions are equally slow and changes to the lightbulb setting often fail to take effect, requiring you to reset the lightbulb, sign out and sign back in, remake lighting groups, toggle Bluetooth on/off, etc. It's frustrating because the only thing holding back this great lightbulb is the god awful app. If you are a glutton for punishment this is the product for you. You've been warned.

      The App is Terrible

      • Verified PurchaserVerified Purchase
      • My Best Buy® Elite MemberElite Member

      The concept is great. A smart bulb that plugs straight into a light socket and is controlled by your phone? Sign me up! The problem is that the app that controls the bulb is absolutely terrible. The interface is clunky and non-intuitive, you have to make an account with them just to register a bulb, and there is NO error checking on the firmware update process. This means that the firmware update will freeze or fail WITHOUT any notification to you, meaning that you will brick a few of these before finally succeeding in an update. When it works, it's great. It has trouble staying connected to the bulb when switching out and in to the app for example. It's missing some basic features (home screen widget for on/off, Android Wear / Apple Watch anyone??). The play-to-music feature is TERRIBLE and is a definite NO-NO for anyone with epilepsy. The bulb runs unreasonably hot, about the same temperature as a regular incandescent bulb, but theoretically uses a lot less wattage (a claim I don't have the equipment to check). Overall, the hardware works great and is really cool, but the app needs a LOT of work. If you're tight on money and just want one or two bulbs, go for it. But for a much better solution, I'd suggest Hue or that other bulb that's Wi-FI enabled rather than Bluetooth.

      The bulb works but the app is terrible

      • My Best Buy® MemberMember

      This is the least intuitive app of the many I have used on my iPhone, iPad, etc. The bulb worked but it took a while to connect to the bluetooth on my brand new iPhone X, though I was a few feet away. It is not easy from the scheduling app (I bought this for automation) to delete old schedules. I selected 'off' at 7 am and the next screen said 3 am (happened several times with random times, so not my inaccurate entry). Then a pop-up asked if I am happy, I said no, and it presented a comments screen that had white characters on white background, i.e. invisible. Then the firmware update that I started 3x went to 20% very quickly each time, and then stalled. I am a technology geek and have updated firmware on numerous products. I have an Apple Watch, multiple iPads, iPhones, etc. I find most apps to be intuitive and very useful. I saw the original video that the company uses in its ads---they pitch the product to the Sharks at about $270 for three bulbs!! Now much cheaper, but it makes me wonder.... I have never taken the time to write a review. Now I have to go back to Best Buy to return.

      Good color rendition - bright - but slow & buggy

      • Verified PurchaserVerified Purchase
      • My Best Buy® MemberMember

      I bought the iLumi bulbs along with the Philips Hue system. They are for different situations. I use the philips hue at home. My iLumi's are used at home and in the office. Its easy to carry around so add color. The colors are beautiful, bright and bold. However the bluetooth implementation is a big buggy, and if you got multiple bulbs in one group, not all will change at the same time. Regardless, I use them for halloween (along with the philips hue), and they are considerably brighter than the hue and probably more color accurate too. The blue, red and green colors are amazing. The downside of it being bluetooth, you got to be in the house to work - otherwise it wont change. Setting a timer sort of works, the bulbs have an internal clock so they work by themselves when they have power, but they arent fool proof. Its not perfect but they do work. I like the wake up sequence for morning. I currently use these iLumi's on either side of my photo light box to take pictures of products. Combined with a flash, it adds depth to my pictures. They are as pricey as the Hue, wish they were a bit cheaper. Overall no regrets buying them.
