Pros
Pro Easy bulb managing
You can select up to 5 bulbs to be part of a group, and a single bulb can be part of multiple different groups. This lets you manage the bulbs room by room, which is much easier than changing each bulb individually.
Pro Lighting modes for any occasion
Through the app, you have access to many lighting modes. From 'disco' which pulses in-beat with the music to timers and configurable color pallets to even selecting a color by using your phone's camera and looking at an object, these lights seem to have it all.
Pro Control the lights from anywhere
Because they use Wi-Fi, these bulbs can be controlled from anywhere as long as you have an internet connection. That means that you can turn your lights on from work if you are expecting a delivery, you can turn them on while you're on vacation to deter buglers and more. Also, it's convenient. You can turn your lights on at home when you leave from work, or by tapping your phone to a NFC tag (if you use third party software and set it up beforehand).
Pro Great at reproducing all colors
Instead of a typical RGB setup, this uses RGBW LEDs. That is, there is a red LED, a green LED, a blue LED, as well as a regular white LED. This allows for more natural whites - regular RGB bulbs try to mix a white color by turning all 3 LEDs on but depending on where you are standing you may be closer to the red LED, so the light will look a bit reddish. The dedicated white LED solves any potential issues.
Pro Self automated
Equipped with a motion sensor to automatically turn on the light when somebody walks in, as well as an ambient light sensor to determine how bright the light needs to be, the BR30 are some of the smartest bulbs out there. They are currently some of the only bulbs that work on their own without needing to be controlled by a phone or remote.
Pro Custom programming
These lights are compatible with IFTTT (If This Then That) - a powerful automation tool that lets you use recipes from the community or create your own from thousands of triggers and actions.
Pro Easy to use presets
The app is where you can make changes to the lights. While they aren't RGB, they do have adjustable color temperature as well as an automatic mode which uses a blue-ish hue in the morning, and a warmer hue closer to evening. You can also manually set the color temperature if you prefer.
You can schedule alarms, as well as 'night mode'. If the bulbs detect motion while in night mode, they will illuminate dimly (around 5% brightness) instead of blindingly bright.
Cons
Con No en mass controls
At most, you can adjust 5 bulbs at a time (if they are in the same group). That means that at night, you may have to go through the app and turn off 5-6 different rooms. There is no universal 'off' button to turn all the lights off, or change them all at once.
Con RGB or white
This bulb has a dedicated white LED, however you cannot use the white LED and turn on another LED to give it a splash of color - its either in RGB mode or pure white. You can attempt to re-create white using the RGB LEDs, and customize the color that way, however it is not possible to use all 4 LEDs at once.
Con Requires a hub
The hub needs to be plugged directly into your router, adding one more thing cluttering the likely already busy area. This also means that you have little choice in the placement of the hub, while other systems have a wireless hub that can be plugged into a wall socket in a closet or somewhere else where it will be hidden from sight.
Con Limited colors
These lights are limited to color temperatures - they don't offer full RGB coloring. They can do shades of blue and yellowish as well as bright white, but no deep blues, reds, greens or other colors.
Con Learning feature needs some work
These lights have a hard time adapting to certain activities. For example, if you are reading and being fairly still, the lights will think that the room is empty and turn off automatically. Because of the learning ability, in the future sometimes the lights will think you are reading and stay on even if the room is empty. It's a tricky situation, but it could be fixed through future updates.
