7. The high-bay luminaire of claim 6 , wherein a second driver is positioned by the second side.
8. A high-bay luminaire comprising:
an upper housing having an outer wall including an exterior surface and an interior surface, the interior surface defining an interior compartment, and a plurality of first heat fins extending from the exterior surface, the outer wall also including a first angled portion extending at an oblique angle toward the center of the interior compartment and a second angled portion extending at an oblique angle toward the center of the interior compartment;
a base connected to the upper housing;
a light emitter connected to the base;
a lens connected to the base and positioned below the light emitter; and
a driver bracket positioned in the interior compartment and configured to retain a first driver against the first angled portion.
9. The high-bay luminaire of claim 8 , further comprising a sensor removably connected to and extending from the base.
10. The high-bay luminaire of claim 8 , wherein the driver bracket includes a lower wall, a first side extending from the lower wall at an oblique angle and a second side extending from the lower wall at an oblique angle.
11. The high-bay luminaire of claim 10 , wherein a first ledge extends from the first angled portion and a second ledge extends from the second angled portion, and wherein a first flange extends from the first side and a second flange extends from the second side, and wherein the first tab engages the first ledge and the second tab engages the second ledge.
12. The high-bay luminaire of claim 10 , wherein a pair of tabs extend from the first side toward the first angled portion.
13. The high-bay luminaire of claim 8 , wherein a first driver is retained against the first angled portion by the driver bracket.
14. The high-bay luminaire of claim 13 , wherein a spacer is connected to the second side of the driver bracket.

16. A high-bay luminaire comprising:
an upper housing having a bottom wall and an outer wall defining an interior compartment, wherein a plurality of first heat fins extend from an exterior surface of the outer wall;
a base connected to the upper housing, the base includes a plurality of second fins aligned with and separated from the first fins to define a first space, and an inner section facing but separated from the bottom wall to define a second space;
a light emitter connected to the base;
a lens connected to the base and positioned below the light emitter; and
a driver positioned in the interior compartment,
wherein an airflow channel is defined by the first and second spaces.
17. The high-bay luminaire of claim 16 , wherein a flange extends from the bottom wall and a hub extends from an inner portion to mate with the flange.
