MAX_CLUSTERED_LIGHTS

How many lights the clustered path carries at once.

const MAX_CLUSTERED_LIGHTS = 320

In depth

This is the number that replaces MAX_POINT_LIGHTS, and it is not bounded by the same thing: the sixteen is a uniform-array size and an iteration of the widest shader's light loop, while this is a row count in a texture nobody iterates in full. 320 lights is three rows.

320 rather than 256 because the light region has to end on a row boundary — see TABLE_WIDTH — and at three texels a light, 320 is the smallest count at or above 256 that does.
