ABSTRACT OF THE DISCLOSURE An indoor luminaire having a concave reflector is provided for mounting at a relatively low height with light directed downward. A high-intensity lamp is positioned within the reflector so that the vertical cut-off angle formed by the reflector rim relative to the lamp is not more than 65°. The reflector has the low portion of its inner reflecting surface formed to reflect light downward at an angle of not more than about 50% of the cut-off angle, to provide low glare at viewing angles of about 65° 85° from nadir.
