Pros
Pro Very configurable lighting options
In addition to basic timers and schedules, you can set the lights to dim over a set amount of time - from 1 minute to an hour - which can help get into and out of bed. The lights are also able to begin turning on with the sunrise (through IFTTT)
Pro Configurable recipies
Thanks to IFTTT (If This Then That - phone app for automation based on triggers) support, you can build your own custom recipes that suit you. There are also plenty of already created recipes from other users that you could use as well.
Pro Compatible with multiple smart bulb ecosystems
Of course its compatible with WeMo's ecosystem, but it is also compatible with SmartThings and Revolv. This allows for more options down the road, and the ability to mix different bulbs in a single setup.
Pro Good color rendering
The WeMo beast out virtually all of its competition when it comes to color rendering - the ability to accurately reproduce colors. It really only suffers when attempting to produce a vibrant, true red.
Pro Choice of hardware
Linked above is the classic bulb style, but Osram offers a few different products that fall into its Lightify family of products. These include an RGB flexible strip of LEDs (really cool desk/counter/home theatre accent lighting), and two other cheaper bulbs that don't offer RGB lighting (one has adjustable color temperature, the other doesn't).
Pro Access to 2 major ecosystems
These bulbs aren't attached to their own proprietary ecosystem - they are built to be compatible with Wink and WeMo which are already established ecosystems which allow for third party automation as well as other features.
Pro Very efficient
While any LED will be more efficient than incandescent bulbs, the Osram Lightify is one of the most efficient smart bulbs currently available, providing 89 lumens per watt (beating WeMo at 87, Philips Hue at 81, and GE Link at 78).
Cons
Con Requires the WeMo Link hub
The bulbs are connected through the WeMo Link which is a central hub, which then connects to your phone. It adds cost to the setup, but thankfully you only need 1 to control a large collection of WeMo Links. This hub doesn't have any wired connections - it plugs into any ordinary wall power outlet.
Con Limited connectivity
There is no option for a remote control or web-based control.
Con Lacks polish
The app isn't as intuitive as the other higher-end competitors, and lights have a slight delay when turning on.
Con Short lifespan
While virtually every other smart bulb is rated at 25,000 hours, the Osram Lightify is only rated at 20,000 hours. While it isn't certain these lights will clunk out before the others, it seems more likely.
