Neil Hotchkiss (in the less-controversial  Common Marsh, Underwater &
Floating-leaved Plants of the United States And Canada) also describes only
one species (erythrorhyzos), but says of the genus:

"More than a dozen other kinds of Cyperus grow in marshes, along the edge of
marshes, or on the shores of lakes, ponds, and streams"

Doesn't sound like a low-light situation to me.
