Direct Downlighting
The greater the cut-off angle, the greater the visual comfort provided by the luminaire due to improved glare control.
Open Reflector Downlight
The greater the cut-off angle, the narrower distribution of light.
Th li hti l t f d li htThe same lighting layout of downlights produces different distributions in the room.
• Downlights with a 30° cut-off angle, thedi t ib ti i t d ti l fdistribution is towards vertical surfaces.
• Downlights with a 40° cut-off angle gives thebest possible compromise between the lighting h i t l f b l d ti l fhorizontal surfaces below and vertical surfaces.
• Downlights with a 50° cut-off angle achieve a high visual comfort for high rooms and

Lighting a Horizontal Surface Downlight Spacing Criteria
Luminaire manufacturers provide spacing criteria (SC) or mounting height ratios (S/MH), for specific light fixtures with direct lighting distribution. These light fixtures include downlights, troffers, and high and low-bay light fixtures. These ratios are used to calculate the maximum recommended installation spacing to obtain an even pattern of light on the surface below the light fixtures. SC ratios help ensure that a space is evenly lighted by slightly overlapping the light distribution from each light fixture.
SC typically range from 0.9 to 1.7, but can be as low as 0.5 or higher than 2.
SC x Mounting Height = recommended spacing for "even" pattern of light
5’-6” feet spacing
Example for recessed downlights:If a manufacturer's SC = 0.7, and downlights are
mounted in an 8 ft ceiling

mounted in an 8 ft. ceiling…..
then the recommended maximum spacing between downlights will be
0.7 x 8.0 ft = 5.6 ft (5’-6” ft.)

Lighting a Horizontal Surface Indirect Uplighting
Ceiling lighting requires sufficient room height to achieve even light distribution Uplights should bedistribution. Uplights should be mounted above eye-level to avoid direct glare. The ceiling offset depends on the degree of evenness

Architects: Briggs Knowles
Briggs and Knowles based their design of the oculus on traditional Victorian skylights but tweaked it to fit a more modern sensibility and outfitted it with fluorescent tubing to recreate the effect in the evening.
