What general rule applies to the spacing of luminaires in general lighting applications?

In general lighting applications, the spacing of luminaires is primarily determined by their output and the specific intended application. This approach ensures that the illumination provided by each luminaire effectively meets the lighting requirements of the space. By considering the output, which includes factors like lumen rating and beam spread, one can optimize the distribution of light to avoid excessive brightness in some areas and dimness in others.

For instance, in areas that require uniform lighting, such as hallways or open office spaces, the arrangement and distance of luminaires can be calculated based on their output to achieve an even light distribution. This alignment with the intended application is crucial for achieving aesthetic and functional goals, such as comfort for occupants and reducing glare.

Choosing luminaire spacing solely based on color, or random distribution, would not properly address the objectives of effective lighting design. Similarly, spacing all luminaires equally does not consider the variances in output or the specific needs of different areas within a space, which can lead to uneven lighting conditions.
