"Microlight" is a European aircraft definition; it has no validity in the US.
Its closest equivalent is a Light Sport Aircraft.
It's defined in JAR-1, and limits the aircraft to a maximum weight of 495 kg for
a two-seat amphibian or floatplane (vs. 300 kg for a single-seat landplane), a
maximum wing loading, and a stall speed less than 35 knots.

The weight limits are stricter that Light Sport, as is the stall speed
requirement, although there doesn't seem to be a max speed limit.
