    I installed these lights in my bedroom and I have created the perfect morning and evening routine using the schedule feature to set up a sunrise and sunset feel. It makes it easier to go to sleep at night and wake up in the morning without the expense of a wake up light.

    These color-changing bulbs are cool...when you can get them to connect to the wi-fi. The connectivity is fickle at best. But they work as light bulbs either way.

    Love these lights. I have them on schedule so these turn on and off automatically. I also turn them on/off from my iphone or smarthome device. My only complain is that I can’t sync the lights with music

    I do not recommend these light or any part of the system, and I will be returning the items I purchased. The C by GE web site paints a partial picture which while elegant and enticing does does not fully explain the negative features of the C by GE lighting products. 1. There is no support for Apple's HomeKit. 2. The devises do not maintain a consistent connection with a network. 3. you must use the C by GE network to control your lights remotely, which I find a serious security risk. 4. your iOS device according to GE only communicates with the devices locally by Bluetooth (although I don't believe this to be completely correct, since you can control the devises over the internet through WIFI and the GE C by GE network. Given the state of technology that exists today, I believe these products to be far behind the technology curve. GE has chosen to confine control of these products to a proprietary network instead of giving the users the option of controlling their own security with direct local and remote connections with authorized and security controlled MAC addresses and direct network to network VPN or other secure connections to the products. Unfortunately sales and marketing have taken precedence over security and user control, while GE has also decided to shun the Apple market.

    They're good it's a little annoying though that you have to keep your device on Bluetooth and location. I'd recommend using a tablet or something that you just keep around the house all day to control these
