A luminaire for below-grade use comprises three primary components: 1) a top; 2) a lamp housing; and 3) a bottom. The top comprises a lens and a lens frame, and may include additional components. The lamp housing can be molded in various depths to accommodate various lighting systems, and is frusto-conical with the outer periphery of its bottom larger than the outer periphery of its top. The bottom includes a junction box and a ballast box. The top is secured to the top of the lamp housing, and the bottom is secured to the bottom of the lamp housing, such that the top, bottom, and lamp housing form a lamp housing cavity which houses a lighting system. Both the junction box and the ballast box are covered to separate them from the lighting system. Electrical wiring connects the lighting system to the ballast assembly, and the ballast assembly to field wire splices. Electrical wiring also exits the junction box through a conduit to connect to an external power supply, and may exit through another conduit to connect to another luminaire or the like.
