I purchased these bulbs for three reasons. First, they were on sale during Amazon Prime Days. Second, being TP-Link Kasa products they work with my existing Kasa App and are also compatible with the Deco router app so I didn't need another app (TP-Link? We don't need Kasa, Deco and Taco- consolidate them already.) And Third, and most importantly, SengLED finally completely and utterly self destructed and stopped working with the Alexa infrastructure. These four bulbs on sale cost less than a two pack of the SengLED brand which require a Zigbee hub that doesn't work without the SengLED back office- which is basically dead now. For the bulbs themselves, they are slightly smaller than old fashioned bulbs, so don't try using them in a lamp that has a spring-grip shade. Setting them up is simple, have the Kasa or Deco app open, select add a bulb of this model and turn the bulb on. You will connect to it via Wi-Fi and then setup will take a couple of minutes depending on how slow/busy your local network is. On my Deco (TP-Link) network, the bulb took about 30 seconds to connect and appear. I haven't had a problem with the bulbs in the month they've been operational, so they already are doing better than the old SengLED bulbs ever did. And even when my internet connection is down; these bulbs still seem to work okay since they are controlled by the Deco routers (note: I've since moved my other Kasa devices over to the Deco app because controlling them from Kasa they do stop working if the internet connection is down.) I've been pretty please with most of the TP-Link hardware I've purchased over the years, and am glad the bulbs are apparently reliable as well.

These TP-Link smart bulbs are excellent. I was using another brand before that worked fine at first, but suddenly stopped working. After switching to these, I could immediately tell the difference. They sync very quickly with my assistant, and the colors are bright and vibrant. Overall, the experience is really solid. Setup was super easy, and the app is great—simple, intuitive, and hassle-free. I highly recommend them. I got them at a great price, but even at regular price they’re worth it. If you find them on sale, don’t even think twice.

Title says all. Added the bulbs to my Wi-Fi network via the TP Link Kasa app, installed TP Link Kasa integration into Home Assistant and after a few minutes the bulbs were detected no problem. After that you are off to the races! Use Home Assistant to configure the bulbs to power on with automations/timers, or use the Kasa software.. your choice. Been using for a couple of weeks and no major issues thus far. The real bummer is that after a power outage, when the power returns the Kasa light bulbs turn back on… even if the bulbs had been OFF before the power went off. I looked in TP Link forums and other folks have complained about this too. It is a known issue that will probably never be fixed (TP Link doesn’t have the best software update reputation). To work around this I applied a preset of “1% brightness” for the power-on state. That way if power goes out and comes back on, the bulbs are only on at 1% and don’t waste as much electricity. Power outages are rare, so this is a minor annoyance. The software seems to have a setting to account for this, but the setting isn’t fully built out. Not sure why TP Link never finished that option. I guess another workaround could be to hook the lamps with the bulbs up to a UPS, but that seems like overkill for this! Other than that the bulbs work great and the colors are awesome. I wish I could use these bulbs in “fully enclosed luminaries” but I cannot. I didn’t realize that until AFTER purchase. But it seems there is no LED smart bulb that can be used in a fully enclosed luminary. I intended to install these in fully enclosed ceiling lights, but after reading that warning decided to place them in some reading lamps instead.

Solid product. The colors are spot on. I especially like the different shades of white through the day if you set them to adjust with the time. Tried other bulbs w Alexa and they either didn't work at all or had to be reconnected all the time. What a pain! I definitely recommend these as smart bulbs for use with Alexa but... The first several bulbs I purchased, I checked the box at checkout to link them to my Amazon/Alexa and bam! They setup immediately with Alexa. I didn't have to use the manufacturer's app. However, I bought another set, checked the same box at checkout, and they did not connect using Alexa. So I downloaded the manufacturer's app and set one up and it broke the connection with all the previous bulbs and Alexa. I couldn't even delete the original ones from the Alexa app. So I... -Disabled the skill from the manufacturer's app within Alexa -Set up all the bulbs using the manufacturer's app -Deleted the Alexa app from my phone and reinstalled it (don't worry, everything is still there once you log in) -Re-enabled the skill in the Alexa app All the lights showed up in the Alexa app again. Everything was good in the Alexa app as far as routines and everything else, except the lights. I had to re-add the lights to the existing routines. So I would suggest setting up the bulbs in the manufacturer's app FIRST and enable the skill in the Alexa app. I hope this is helpful :)

There have been some break in’s at some homes in our neighborhood recently. We are away at a second home several days per month and didn’t want to have a dark house while we’re gone. We already have a house alarm system that is monitored but feel that intermittent lights in the house would be an additional deterrent. We have WiFi set up and the nice thing about these smart lights is you don’t need a hub for them to work. They require 2.4 mhz and our Xfinity doesn’t separate 2.4 and 5. The quick work around is to go to your Xfinity app and select separate WiFi bands- I renamed the 5 mhz by adding a 5 to my network name. It’s then simple to connect the lights to your WiFi’s original name and then after connecting you can go back to Xfinity and deselect separate WiFi and you’re all set.

I don't know why I though these would be good. I have a Kasa smart plug in my living room and it works, maybe that's why I thought their products would be good. It does seem light Amazon promotes this brand as working well with Alexa. Let me tell you my experience. A while back I found a package of Kasa smart plugs on a lightning deal so I bought them. Not long after I bought an Alexa device (maybe it was Prime Day, I don't recall) and it came with a smart bulb -- NOT A KASA but a different brand. Now I am just venturing into making my home "smart-ish" by use of lights and plugs. The Kasa plug worked great in my living room as I said, but I didn't use the bulb right away, in fact I forgot about it. Later I ordered ONE Kasa bulb and later some off brand plugs - mind you I still had a Kasa plug from the lightning deal from earlier. The problem I ran into with the Kasa product was that unless they are within a few feet of my router they will not connect. The Kasa bulb in the lamp near the router works great! When I try to use a Kasa bulb or plug in my bedroom (not that far from the router) I keep getting told by the app that it won't work because there is no connection or it is too unstable. However, when I put the off brand bulb in my lamp and plug in a device to the off brand smart plug (both in my bedroom) they connected instantly and I've had no problems at all! I cannot imagine I am the only person experiencing this issue. Of course these things I'm describing happened a little while back, not long, long ago but long enough that I forgot which bulbs I had where so when I found a pack of 4 Kasa bulbs on a lightning deal I thought the price was too good to pass up. I am still trying to "smarten up" my home. I received them today and put them into lights in the very same rooms where I have lesser known brands of smart bulbs or plugs and low and behold the Kasa app is telling me exactly what it told me last time! That I have a weak connection or no connection to the wifi in those room and the bulbs will not work there!! It is so frustrating because I know that is not the case! These Kasa products are simply garbage, do not waste your time. Buy the off brand that will connect nearly instantly without the headache of trying and retrying to connect plugs and bulbs that are never going to work! I'm sending these back. Sure, I got them on a deal, but they weren't so cheap that I don't want my money back!

Used these for my outdoor lights to set the lights to turn on before sunset and off at 11. Love that I can control the lights from my phone and even change colors if I want to! App is great and connects to Alexa well.
