To better determine which shield is right for your project, it’s important to understand how each shield works. Lumec’s house side shield works by reducing the light in the back of the fixture, to mitigate light spill behind the pole. This is helpful when the fixture is located directly in front of one or more homes, and residents wish to reduce the amount of light coming in their windows at night. Reversing that scenario, Lumec’s front side shield reduces the light in front of the fixture, to mitigate light spill across the street. This is helpful for minimizing the light spill affecting residents on the opposite side of the street from the fixture.
Sometimes light spill challenges are not contained to the front or the back of the fixture. In that case, your project might need a left side shield, right side shield, or cul-de-sac shield. With the left side shield, you can reduce the light on only the left side, to mitigate light spill on the left side of the fixture pole. Likewise, you can reduce light on the right side of the pole by using a right-side shield. If your light spill is a problem on multiple sides, then you can use the cul-de-sac shield, which reduces light on both sides of the fixture, as well as the back. With the cul-de-sac shield, your light is contained to the front of the pole. You can see the impacts of these shields below:
