When comparing GE Link vs Lifx, the Slant community recommends Lifx for most people. In the question“What are the best smart bulbs?” Lifx is ranked 2nd while GE Link is ranked 14th. The most important reason people chose Lifx is:
While few other SmartBulbs get as bright as a regular 60 watt bulb, the Lifx gets even brighter. Instead of just using it for accent lighting, these smart bulbs are some of the only ones that can effectively be used as a primary lighting source.
Ranked in these QuestionsQuestion Ranking
Pros
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).
Pro Very bright
While few other SmartBulbs get as bright as a regular 60 watt bulb, the Lifx gets even brighter. Instead of just using it for accent lighting, these smart bulbs are some of the only ones that can effectively be used as a primary lighting source.
Pro Simple setup
As soon as they are plugged in, the lights will turn on and start broadcasting a Wi-Fi signal. To pair it to your phone, just connect to that Wi-Fi signal. After you connect, you're done and can switch back to your home Wi-Fi.
Pro Third-party integrations
The bulbs can hook into the Nest Thermostat, Nest Smoke Detector, as well as IFTTT (If This Then That - a popular automation app based on 'recipes').
Pro Different bulb options
The Color 1000 comes in two variants - one is a compact A19 size, while the other is a BR30 size. The A19 produces 1055 lumens (equivalent to a 75W bulb), while the BR30 produces 970 lumens (equivalent to a 70W bulb).
Pro No hub required
The bulbs connect straight to the phone, meaning there's no need for a hub which reduces the upfront installation cost.
Cons
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.
Con App lacks features
The app doesn't allow for light scheduling or custom color cycles.
Con High brightness washes out colors
The colored RGB lights can only achieve 50% brightness on their own; after 50% white LEDs are also turned on to achieve a very high total brightness. However, mixing white light with colored light will dilute the colors so that red light at 70% brightness will look more washed out than red light at 50% brightness.
Con Heavier, and warmer than other LED lights
To achieve their high brightness, the Lifx need more diodes than other LED bulbs, which means that they get hotter. To help deal with the heat, there are more heat sinks which adds the weight (they weigh 10.4 ounces each). Despite the heat sinks though, they still run a bit warmer than other LED bulbs.
