Are these the same ones?

It looks like it.
Max lumens rating?
Not compatible with Philips Hue. 
Yet another app to control these? Nope. Not interested.
Here’s the Philips page. Says up to 1200 lumens.
Thank you! I will see if I can offer a lower price on ebay 
The eBay listing is for only 1 bulb, not a 4 pack. Unless I am reading that wrong 
Not understanding the functionality of these bulbs. Can i stick them in my ceiling high-hats or my floodlight frames on my deck, or do they require some kind of wifi setup?
If they’re WiZ they probably require WiFi for wireless control and customization. The Wiz app isn’t too shabby. I still have one bulb from those I bought at Costco many years ago.
