Final answer:
Fully shielded luminaires, low-pressure sodium luminaires, and luminaires with specialized optical designs are exempt from the SSc Light Pollution Reduction uplight and light trespass requirements.
Step-by-step explanation:
The SSc Light Pollution Reduction uplight and light trespass requirements are aimed at reducing light pollution and its negative impacts. However, there are some types of luminaires that are exempt from these requirements. One example is fully shielded luminaires, which direct light downward and minimize light pollution by preventing light from being emitted upward or sideways.
Another example is low-pressure sodium luminaires, which produce a monochromatic yellow light that is less disruptive to the night sky compared to other types of lighting. These luminaires are often used in areas where minimizing light pollution is a priority, such as near observatories or wildlife habitats. Additionally, luminaires with specialized optical designs that minimize light spill and glare, such as full cutoff or semicutoff fixtures, may also be exempt from the uplight and light trespass requirements.
