A lighting unit for use in illuminating an oven cavity is internally, asymmetrically constructed and externally, substantially symmetrically constructed. Due to the symmetrical external construction, the lighting unit can be readily mounted in an oven cavity in multiple configurations to establish varying levels of illumination depending on the selected mounting arrangement. In particular, the lighting unit can be rotated prior to insertion in a side wall opening of the oven cavity, with the illumination intensity varying depending on the selected mounting position. In one preferred embodiment of the invention, the outer shell is rectangular in shape to establish two distinct, potential mounting positions upon rotation of the lighting unit 180°, with the level of illumination varying in the order of at least 45% between the two mounting positions.
