Easy to install and setup with the Hue Bridge, previously tried buying from Amazon and Best Buy but either got my order canceled or sent the 5/6 inch version instead. They were a little stubborn connecting to hue bridge but turning them on and off again made them eventually appear in the app.
The light is great and suits my needs almost perfectly. The larger system has a flaw for people with more than 50 devices though (which is VERY easy to get to). One hub can only handle 50 devices. Adding hubs is easy. However, you can only operate the devices on 1 hub remotely per account!!! I have 3 hubs with 100 bulbs, sensors, etc. So, I only have access to 1/3 of them when I'm away from home...baring the creation of 3 different accounts with different emails, passwords, etc. (Note: You can access all three while in network at home, just not remotely.) Only being 'smart' when I'm around is not a good measure of smart.
The hue light fits into my existing can fixture and allows control of the color and intensity of the led from my phone. Works quickly and we enjoy having them.
