Do you need to replace your fixtures at all to take advantage of these LED bulbs?
I saw that some LED brands/bulbs required something like that? (maybe it was a a built in fixture and LED lamp/bulb)
Hi. I’m according to the listing you don’t have to replace any fixtures. Everything is built into the lightbulb but for full functionality you need to buy a “Philips Hue Bridge.” It does work without the bridge but it would be through the app and only when you’re in bluetooth range. With the bridge it’ll work over wi-fi and can be controlled from anywhere as long as you have wi-fi and you also gain the ability to schedule certain events and have multiple products work in sync.
Here’s the listing on Amazon: https://a.co/d/8DIraWm
Hope this helps
