Flux Bluetooth LED Smart Bulb - Wireless Multi Color Changing Light For Kitchen, Bedroom- App Controlled Sunrise Wake Up Light - Sunset Sleeping Light - Dimmable Colorful Night Light - No Hub Required

These bulbs are great! They respond to the Bluetooth commands quickly. Setting them up is a breeze. I just connected one at a time to figure out where in the room I installed them and renamed them using the app so I would have their location saved. The app is easy to navigate and fairly intuitive.My only critique is the limit to how many bulbs that can be grouped together. I have a total of 14 that I want to control as a group and as smaller groups within the larger if need be. They are only able to group into one set at a time and the limit of 5 per group is a bit frustrating. This means I need to have three phones or tablets with the app installed, working simultaneously, to adjust the lights. Despite this slight setback, they are a wonderful addition to the room and help control the mood with ease.I would recommend these to any who want direct control over their lighting needs. Not only just dimmable, but color programmed, music directed, phone mic inspired, and you can use your phone's camera to show the lights what color they should be by pointing the camera at various colored objects. You can create your own color patterns and schemes. These are worth the money.

This product is AWESOME! I've been a fan of colored lights for years and this product is definitely an upgrade to your generic one colored light or colored track lighting. The mobile application lets you program your Flux right from your smartphone - very convenient when you are watching tv on the couch and do not want to get up to turn off the light or to a different color. The standard color wheel allows your to turn the Flux to whatever color you are feeling and even lets you save five of your favorite colors for quick access. When I have company over, I set my Flux to the gradual change setting where it changes slowly between either a range of colors, a few colors, of one color. There is also a setting that allows you to have your Flux change to music that plays from your smartphone and one where you can take a picture of a color and the Flux will duplicate it. Personally, I would recommend purchasing multiple bulbs (at least two) so you can really set the mood in your room. I have one in a lamp and one in a standing light tower on opposite side of the room. There is a master setting in the app where you can control both lights at the same time so you don't have to individually adjust each bulb. Currently, I have a LED strip behind my tv that has about 20 different color choices. This product is so versatile that it can match the color of the LED strip using the color wheel function (pictured, the Flux is in the lamp on the right). You can also adjust the brightness to your liking and the product also emits a warm yellow glow for a normal looking light. No one would ever know its a Flux if you don't want them to! On top of this great product, the customer service is fantastic. They sent me a $5 coupon toward my next purchase. I haven't had any problems and I've had this product for about 4 months now. I'm sure if it died I wouldn't have an issue getting it replaced.

In terms of functioning as a standard light-bulb, this is as good as it gets. The physical product is superb. It offers a bright LED light with the full RGB spectrum, warm light (think tradional bulbs), as well as a brightness slider for all colors. Not much to say here, but if you're purchasing this product, then you probably care more about the wireless functionality.I use a Samsung Galaxy S4 with Android 4.4. I had no issues scanning for the bulb, and adding it within the provided app. The app itself is very basic, however. It allows the selection of colors and mods as described above, but also the creation of timers. Timers tell the light to switch on/off and/or select a certain color mode or brightness. They work well enough, but they do not allow for a slow fade on or off. One of my goals was to use it as a sort of alarm clock, so the slow fade is important. I worked around this by setting a series of timers to increasing brightnesses, which has worked well for waking me up in the morning.Now that we've covered what the app can do, let's look at what it can't do, but could do.My ultimate goal would be total automation of this bulb. As of now, you must use the app to turn the light on and off (as opposed to a lightswitch or) in order to not erase your timer settings. Ideally, I would like my phone to be able to turn the light on upon first bluetooth connection (perhaps between certain hours). At the very least, I would like an Android widget to toggle power on/off from my front or home screen. Neither of these things would be very hard, especially if the developer were to work on Tasker implementation. Tasker is a tool for android which allows for the automation of events, and for it to be compatible with this device would solve every problem. This app is far from proprietary, and it is only a matter of time until another developer or company steps up to create a better version.Overall good product, but the app's functionality leaves much to be desired.
