Too many duplicats of the same actor destroying performance, which Parent class to use?

I am building a maze game and in this game there are pellets like pac man that disappear when the pawn overlaps them. but the levels are rather large and i am uncertain how to build them so the FPS doesnt tank if there are around 2000 in a level. Right now I am fine with a very basic mesh that has an emissive material or preferably a colored point light and of course a collision. The game is meant to be a retro style game so no fancy graphics i just need to load a large number of items in the map. Not sure if there is an appropriate parent class for this? what is the cheapest performace cost i can mange this with?
