5 Ways to Avoid Light Trespass on Outdoor Lighting Projects
March 19, 2021
If you have a street light outside your bedroom window, or any type of bright light, you understand the frustrations of light trespass.

Let's say that your next project includes designing the lighting layout for a local baseball field or any other outdoor sports-oriented facility. It's imperative that you consider the effects of light trespass from your finished project on the surrounding areas.
The definition of "Light Trespass" is when spill light is cast where it in not intended. With all the lawsuit-happy people in this world today, the possibility of creating unwanted light on a neighboring property must be given the utmost attention. Not only is it a frustration for your neighbors, but strict regulations have evolved and some with steep penalties in many cases.
First, let's cover 5 most important components to avoid light trespass on your outdoor lighting projects:
- Employ and experienced lighting designer.
- Use full cut-off fixtures
- Choose practical brightness levels
- Proper placement and aiming
- Verify all fixtures from all viewing angles
In addtion, there are a few questions you can ask to avoid light trespass before it becomes an issue:
- What are the dimensions of the area needing new lighting or updated lighting design?
- What is the desired light level (in footcandles or lux) for the area being lit?
- What are the light trespass regulations for your type of property (area specific)?
- Are there any natural or manmade barriers that will dilute the light that reaches a neighboring property?
- Do I have a solid lighting layout/design to assure my project is a success?
- Are there specific fixtures or shielding components I can use to effectively direct the light?
Light trespass regulations don't exist in every state and can evolve rapidly in states that do have regulations. You can find a basic summary of the regulations in each state or district at The National Conference of State Legislatures
website. Louisiana and Mississippi are among many states that do not have light trespass regulations. In these cases, we encourage you to review your state or municipal regulations to avoid any issues or penalties.
