Should i get an access point?

Ok so I use tuya lightvulbs with local tuya. And currently I have my router running a 2.4g guest network which I use for all those devices.

Just moved into a new house and I'm gunna need to add 24 gu10 bulbs into that and another 5 normal bulbs.

So people who know more about wifi networks than i do. Should I get another router to use as an access point or do you think the router can handle that many devices with a massively noticeable drop in performance?

Edit: thanks for the replies everyone looks like zigbee it is
