If you have Home Assistant (or similar) for your automation and you are starting, I'd recommend Zigbee or Z-wave devices. A few wifi bulbs like the ones from this deal are OK, but you could get in trouble (signal drop) as you keep adding wifi devices to your network.
If you live in a small apartment and don't plan on adding too many bulbs, then these will work.
Zigbee and Z-wave create their own mesh network which makes it more reliable and they use a different protocol so all you wifi devices will be OK.
For Zigbee devices I think Philips Hue are the best/more reliable but of course way too expensive. Ikea TRÅDFRI are recommended and not too expensive. Seng led are cheap but I do not recommend them since they won't act as router/repeater for the Zigbee network, compared to TRÅDFRI or Hue (unless this was changed recently).
The downside of Zigbee or Z-wave is that you also need a hub/gateway to control your devices but since you are asking about automation, I think at some point you will have to deal with some sort or hub (RF, Z-Wave, Zigbee). I think some Amazon Echo devices can act as a Zigbee hub but I'd recommend using something like a Zigbee USB stick and running zigbee2mqtt and then you can do all your automations in Home Assistant and/or Node-RED.
Good luck!

These are great bulbs. I've been using a couple of these for several years in my Alexa based smart home. Just be aware that these bulbs are 800 lumens (equivalent to 60 watt incandescent bulbs). Kasa makes brighter bulbs of 1100 lumens, but they are more expensive. Kasa (TP-Link) makes very good products.

I got two packs of refurbished ones and they work perfect. They are a little dim compared to my wyze light bulbs. But wyze bulbs don't play nice with my hoobs iot manager.

Home automation enthusiasts, are these bulbs you'd recommend or do I need to bite the bullet and get something like the GE ones with the bridge? I've seen the latter in action, especially with the "scenes" stuff which is really neat. These are obviously WAY cheaper, so I figured I'd at least ask.

I only owned one of these bulbs and 16 of the Sengald (or how ever you spell) zigbee garbage bulbs. The Kasa is way better and doesn't need the stupid SmartThings hub. Kasa makes the best switches and maybe bulbs in the smart home atmosphere but DO NOT USE their cameras. They do not provide MFA and anyone could log into your account and watch your cameras.

Anyone with your password. This is not a problem if you have a robust and unique password.

The coupon code is 5bulbs. It is written in the deal description and I just confirmed it drops the price by $5.

Are they still phasing out the Kasa line of products?

Thank you! I've had a deal alert on these for a bit waiting for the price to drop again since I missed it last time.
