A lighting panel has a planar upper face and a lower face having a system of aspherical female lenticules arranged in an overlapping offset pattern to form a network of diamond-shaped domed cells. The panel provides adequate light control and may be made thinner than a panel having female conical prisms. The panel also is substantially lighter weight than a panel of equivalent thickness having conical prisms, over a wide range of thicknesses. The pattern allows panels having a wide range of thicknesses to be made from the same tooling.
