Mine (Boscoyo chromaglow, they're pretty common) have a bunch of LED inside, not just one. But yeah, if you want a lot of light from a small number of channels, look at WS2811 floods. Or DMX PARs or floods.
IF you are looking for large pixels search on carnival, fairground or cabochon pixels. These are common terms for multi-led pixels. Not likely as bright as a floodlight but they are much larger than a 12mm pixel.
