Z-Wave/Zigbee still relevant?

I just did a search of homedepot, lowes and amazon and sadly beside few rare silvania bulb, couldn’t find any affordable alternative to Hue lights. Only strong alternative seem to be the ikea lightbulbs, very affordable and can be hacked to work on hue bridge. Some of the other Zigbee bulbs were on clearance which did worry me a bit.

Yes just doesn’t seem to make sense that a router has to handle each lightbulb separately.

But my understanding is that Zigbee is also 2.4 Ghz… so same issue?

So from all your replies - no one mentioned Z-wave, so I guess dead standard.
Anyway, if I get a good deal on a hue bridge, I will invest and try to get some ikea + hue lights.

Thanks!

Erik.
