The Lithonia Downlighting product line includes 6-inch and 8-inch apertures for use with incandes-cent, compact fluorescent, low voltage and HID sources. Choosing the correct aperture for an application often depends on design parameters (requirements) or personal preference. The 6-inch aperture provides a smaller opening in the ceiling, while the 8-inch aperture product offers good lamp cut-off and glare control.

5 The 8-inch aperture is ideal for higher mounting heights. Fewer 8-inch fixtures are required to achieve the necessary footcandle level, which results in a lower initial fixture and lamp cost and energy chart below summarizes the results of a common layout comparing 6-inch and 8-inch aperture downlights. The layouts were performed utilizing Visual Lighting design cut-off is defined by the angle at which the lamp becomes visible. Our reflectors are designed to bal-ance good lamp cut-off while maximizing lumen output, creating high fixture efficiency.

6 High-efficiency downlights allow a space to be lit with as few fixtures as possible, resulting in energy savings. Efficiency cannot be the only consideration. A bare incandescent lamp offers 100% efficiency but also has a high amount of glare and downlighting subtly lights an application without drawing attention to the ceiling plane or the fixture itself. The Lithonia Downlighting product line has properly-designed reflectors that offer low angle aperture brightness at a high angle. The result is minimized discomfort and Downlighting products offer the proper combination of efficiency, glare control, and low brightness to meet both functional and aesthetic D O W N L I G H T I N GLIGHTING GUIDE Rugged, galvanizedsteel pan frame and cup attaches to reflector with pre-mounted screws.
