I was excited about the product but the iOS app didn't work at all. To begin with, I was not able to create a C by GE account which was a must for using the bulb. It kept saying "Internet connection not found" although I was connected to Internet. Then I found that I had to turn off my VPN which I did and then the activation email was received. The activation email link didn't work though. It kept giving the "Server Error" (attached). Then I called GE Customer Service and they said it is a known issue and they don't have the estimated time for fix. I am not sure if this is temporary or permanent based on reviews I found within the C by GE app. Looks like I am not the first. Didn't expect this from a good brand like GE.
Hi SaravK thanks for reaching out to us. Our servers experienced a momentary outage yesterday which was resolved quickly. I can assure you that that is not the norm.

If you ever want to live a happy life. Do not ever buy or use the word cync in your life. Horrible, horrendous and utter nonsense product ever manufactured in the known and unknown universe.
Nothing about the product is smart infact the should change the product name to stupid bulb. When they do it then I will give 5 billion stars too.
We deeply apologize for the less-than-ideal experiences you've had overall with your Cync experience. We would love an opportunity to make this right. Please consider contacting our support team at 1-844-302-2943 if there is anything we can address or resolve for you. -Cync Support

Within 6 months bulb would no longer light up at all, and the app would say it was working but it just wouldn’t light up, this tells me the inside board was probably still good but the actual lighting assembly failed

I was skeptical at first because I had previously been using LIFX bulbs at my sisters during my last visit. So in my mind it was LIFX or nothing. But since stock of the 1100 lumen LIFX bulbs had been out of stock for some time i got tired of waiting. Now these aren’t perfect but they’re certainly not the worst compared to some other cheaper brands you can find at your local Walmart. For this review do note I am using both bulbs in lamps in the same room. So I’ll be reviewing based off using both. Also do note these are wifi bulbs not Bluetooth.
App:
The app I’d say is 8/10. It’s really easy to use, the setup on my trash DSL wifi was way faster than my old Geeni app setup. No flashing bulb and super slow install times. It’s likely you’ll have to install a firmware update for the bulbs but it took seconds, not minutes. Automation settings are pretty good, a little cumbersome when you’re trying to edit them because it’s so many clicks to get through it, but this is UI issue that can be fixed in future updates. Color wheel selection, I am pretty partial to LIFX app UI when it comes to their color wheel or band layout. GE has a giant color circle that you tap and drag certain areas of color to achieve the color you’re looking to get. I’ll get into more of that in the vibrance area below. Selecting the color is just ok BUT again this is a UI app issue NOT an issue with the bulb. It’s still better than Geeni and any other ones you can use thus far minus LIFX. Other than that the app works better than expected.
Brightness:
For all your white and warm lighting needs these are great. Cool white to warm soft amber light these are quite bright. There is a section of the app that controls the white light vibrancy, it is separate from the main color wheel. This was a great UI addition and makes using normal light to color light very easy and non complicated.
Color Depth & Vibrance:
When shopping for multicolor lighting, everyone is looking for color vibrance and saturation, brightness and well a full spectrum of color. If I was to rate the overall vibrancy of all the colors as a whole I’d give this 8.5-9/10 and here’s why:
Blues - the entire blue spectrum from deep to light to teal and aqua colors are all very saturated and vibrant. 10/10
Reds - As with the blues, the reds are also extremely saturated, bright and vibrant, and a relatively excellent spectrum. Deep red to hot pink to magenta you’ll be able to achieve quite a few red colors. 9/10
Orange - the orange spectrum is good when you can nail it on the color wheel. Because it’s a wheel of color as opposed to a band with a slider and orange being a small area of the wheel compared to your blues, reds, and green area; it can be a little irritating to get the right orange. However, once you figure out how to drag the color selector right you can achieve deep warm orange to a light amber color. Again this is a UI issue that GE can address in a future app update, this isn’t a bulb issue. 6.5-7/10
Purples - The weakest of the bunch and completely incomparable to LIFX purple achievement. This may be again due to the UI of the app itself and not necessarily the capability of the bulb itself. Purples are very light, not very saturated in color nor vibrant. The spectrum for purples is cumbersome to achieve as a whole. But you can still get them they just are to me a bit flat. Which is kind of a huge bummer. However this may also be fixed by a UI update to the app. 2/10
Green: the green color spectrum here is pretty good! It’s not the largest part of the color wheel but I’ve been able to get a good neon, light green, and relatively deep green. I do wish it would do like a sage green color or some darker type greens for better ambient usage of this color. However I’d say it’s pretty good thus far. This again is potentially a UI issue with the app and how you select color with the color wheel. 6.5-7/10
Yellows: like the purples this was a weak color among the bunch. Lacking in vibrancy and saturation as well as overall spectrum. Potentially also a UI issue with the color wheel selection. I’d give this 2/10.
So overall, C by GE Direct Connect are great lights, they do connect via wifi as opposed to Bluetooth. The Bluetooth connect ones are just C by GE, if it doesn’t have direct connect in the name then it’s not a wifi version. The Bluetooth versions are trash don’t get them. These are a way better buy! How they compare to LIFX, well they’re a strong competitor but are definitely not quite on their level yet and this mainly has to do with the app not the bulb itself. The bulbs themselves are good, the color selection within the app needs to be looked at and changed. This doesn’t mean they aren’t usable, they’re usable and worth the purchase since LIFX can’t get it together with their supply chain availability. Would I purchase an 1100 lumen c by GE direct connect... yes is priced appropriately. Overall I’d give this product a 4.5/5 stars if I could!
Hi Itsjkay thanks so much for reaching out! That was a very in depth review of the highest caliber. On behalf of us here at C by GE we sincerely appreciate you taking the time to review every aspect of our app as well as various colors of this product. If only there was a way to pin this review.

I use these with my Google Home, making my home a smart home. I upgraded to all of these bulbs in my house, and I have had no issues using it with Google Home at all. I highly recommend setting these up on Google Home so you can take advantage of using voice commands. I honestly feel this is the best way to go. You also keep your light switches always looking clean and never dirty; and one less area to clean up, and worrying about germs and viruses will be a thing of the past, at least in those areas. I have used many other products in the past. Still, I found these to be the quickest and easiest to set up and install; even when I want to move a bulb to another area where I no longer want it in one location to factory reset it, there are excellent video tutorials on YouTube how to do everything that LG has put out. I also like how the bulbs are turned on and off; they don’t just abruptly turn on and off; they gradually turn on and off, which is much more aesthetically pleasing in your home. You will pay more for these, but you get what you pay for a great product.

They work as you'd expect for a LED light bulb. The app is a bit clunky to use though. Kids like the color and dimming options.

It a really good light bulb and the app is not that hard to connect. If there any issues just turn on and off the Bluetooth and restsrt the bulb by flipping the switch 5 times. That worked for me and hooked it up with google home and its amazing and easy to use. Has also routines to set up.

I like this smart bulbs. I did have a little trouble getting them to connect with my Alexa hub. I downloaded the app for Sync and followed the instructions but it took quite a few tries before they connected. Once they did they worked well with Alexa. But when I got up the next day, they had disconnected. They are still disconnecting regularly. I'm like the colors a lot. But there aren't as many gradients as they claim. Adjusting the colors is a simple color wheel and doesn't really do the possibilities justice. The colors that do work are good, and the dimming options on the white colors works really well. Different types of white light, like sunlight or early morning are absolutely terrific. Good bulbs but check the specifications carefully and maybe go with the matter enabled option for easier hookup.
