When comparing Osram Lightify Classic vs GE Link, the Slant community recommends GE Link for most people. In the question“What are the best smart bulbs?” GE Link is ranked 13th while Osram Lightify Classic is ranked 14th. The most important reason people chose GE Link is:
Once you get the Wink App working, controls for the bulbs are simple. Whether you are modifying one bulb at a time, or grouping them to adjust many all at once, the controls are simple and work fairly well. Automating bulbs is just as easy - from basic scheduling (turn on in the morning, off when you go to bed for example) to recognizing when your phone is near and turn on by themselves. If you want to go deeper, you can use the Robots feature, which allows you to craft your own automation recipe and dip into external triggers.
Ranked in these QuestionsQuestion Ranking
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).
Pro Easy lighting management
Once you get the Wink App working, controls for the bulbs are simple. Whether you are modifying one bulb at a time, or grouping them to adjust many all at once, the controls are simple and work fairly well. Automating bulbs is just as easy - from basic scheduling (turn on in the morning, off when you go to bed for example) to recognizing when your phone is near and turn on by themselves.
If you want to go deeper, you can use the Robots feature, which allows you to craft your own automation recipe and dip into external triggers.
Pro Great color range
These bulbs can manage to display 90% of the color index - more than any current RGB LED bulb. It scores very well in all colors, expect pure red (about 60%) and pure blue (about 74%). Different shades of these colors all perform well.
Pro Compatible with many products
The GE Link is part of Wink's smart home platform standard, and are compatible with other products that utilize Wink (Honeywell, Dropcam, Philips Hue and more).
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.
Con Buggy software
Between installing, registering, and connecting, the setup process is very slow and buggy. Even once connected, changing the colors or settings takes longer and appears more choppy than competing bulbs.
Updates can fail to install properly multiple times in a row (even with restarting your phone and unscrewing the bulbs).
Con Hub required
To access any smart features, you will require a hub. There are different hubs available, with more to come. Currently there is the Link Hub ($30) which will handle lighting, or the Wink Hub ($50) will be able to work the lights as well as other smart home systems. There's also the coming-soon Wink Relay ($300) which will have a touchscreen and act as a wall mounted smart hub.
Con Inefficient compared to other RGB bulbs
The GE Link requires 12 watts to produce 800 lumens - the TCP LEDs and Belkin WeMo provide the same lumens at 11 watts and 9.5 watts, respectively, and the Philips Hue provides 750 lumens using only 9 watts.
The GE Link is one of the most inefficient RGB LEDs available, however it is still many times more efficient than incandescent bulbs.
Con Limited dimming
While other Smart LED bulbs can dim right down to 0.5% of their total brightness, the GE Link will only go down to 10.2% brightness before it turns off. While this is still fairly dim, it would be nice to have an even larger range to make transitioning to bedtime more effective.
