1. An acoustic lighting system comprising:
a first light panel comprising:
a first substrate defining a plurality of cut-out regions therein,
first and second spaced-apart power conductors disposed on the first substrate,
a plurality of first light-emitting elements disposed on the first substrate and electrically connected to the first and second power conductors by a plurality of conductive traces,
first and second connectors electrically connected to the first and second power conductors respectively, and
a rigid sound-absorbing material, wherein (i) the first substrate is disposed over the sound-absorbing material and (ii) none of the cut-out regions defined in the substrate intersects the first and second spaced-apart power conductors, the plurality of first light-emitting elements, or the plurality of conductive traces;
wherein the sound-absorbing material does not directly underlie the first connector or the second connector, or
wherein the first connector is disposed on a tab protruding from the first substrate and the sound-absorbing material does not directly underlie the tab.
