Great mood lighting
Make and save your own themes
Dimmable (but don't use with a dimmer switch)
Some cool pre-canned effects, i.e. Flicker, Color Cycle, Spooky, etc. (these are customizable)
consume very little power
I like the simple app
No hub needed
Convenient to turn on and off all lights in the house at once.
Geo fence. Lights will come on for you, or the kids, just by pulling into the driveway. Safety feature.
Keep your phone by your bed. If you hear a bump in the night you can very quickly turn on any light, room full of lights or all lights.
At 25% power, in color mode, they are burning less that a watt each.
I like that you can turn the I.R. mode off. With I.R. on, below around 9 watts your power consumption will jump from 0.5 watts to 7.6 watts. Even when you believe the light are off - they aren't really. They are giving off I.R. light and burning 7.6 watts each.
Grouping lights by room and by house.
Great for entertaining. You can put up some soothing, cozy colors. They really set the atmosphere - when you have enough of them.
Decorate your room, or house, with light. Best with white or off-white walls.
They are heavy. I can see the horizontal arms, under the lamp shades, holding the sockets sagging under the weight. Most light sockets were designed for an incident bulb that weighs next to nothing. These Lifx bulbs replaced normal 40 watt equivalent or 4 watts LED bulbs that also weighed next to nothing.
They can often loose connection, although I haven't noticed as much of that lately.
I probably returned at least a dozen that would never connect or stay connected even after bulb resets. (Turn on and off 5 times)
They get pretty hot for an LED bulb. The 4 watt bulbs barely got warm and that's good for your AC.
For best signal the router manual says: "Place the router away from large glass surfaces." If your light bulb is enclosed in a ceiling fixture, chances are it's behind glass. But that's not why mine are only in table and floor lamps. Also not due to the builder-grade ceiling lights with weak, flimsy assembly between the socket and the light fixture. Although if I tried installing one in a ceiling fixture - that might become a reason.
When you turn on a light switch, your probably doing it because you need light. My Lifx light would come on set to Red or Blue, etc. at 25% power. This does not work if you turned on the light to look for something. So you have to go find your phone and open the app, set it to White, turn up the brightness. That's not convenient. So ceiling lights are for actual light and table and floor lamps are for mood lighting.
With the weird shape, they won't work with every fixture. They barely fit under some of the Tiffany shades. Some of the shades had to be raised a small amount to accommodate the squared off corners.
If you have a lot. They take up a lot of spots on your router.
The BR30 version doesn't not completely turn off unless you cut the power. Once your eyes adjust to the dark room, you'll see a very faint glow - even through a translucent lamp shade. It's very dim and not a big deal but it is definitely not fully off.
The A19s are all in Tiffany lamps with cut glass shades - so they are behind glass, mostly. Something the router manual says to avoid. The BR30s are in floor lamps with either Alabaster style or cut glass shades. Again, behind glass.
The metal arms on the table lamp sockets are metal tubular steel and built solid - yet because these arms are horizontal I can see the arms sagging under the weight. Some of the bulbs are sort of peeking out from under these shades - not so with the LED bulbs that were in these lamps. The socket on one arm actually broke under the weight. I have yet to try and fix that.
