A Planning Board subcommittee has released the first batch of results from a townwide survey on outdoor lighting.
Around the time of the Town Meeting vote in March 2026 in which residents approved new restrictions on outdoor lighting to protect wildlife, the Lincoln Dark Skies Committee sent out the survey to better understand residents’ experiences with nighttime lighting and their preferences for future lighting practices in Lincoln.
The amended zoning bylaw establishes Dark Skies lighting standards for new construction and major renovations as well as new fixtures on existing buildings. It requires:
- Shielding to direct all light toward the ground
- A maximum light color temperature of 2700K (down from the current 3000K)
- Limits on brightness (900 lumens)
- New rules on hours of operation for lighting not associated with active use
The measured passed with a 195-48 vote, clearing the required two-thirds majority hurdle. Earlier in March, the Planning Board endorsed the proposed zoning amendment by a 3–1 vote, with board member Gary Taylor casting the only “nay” vote.
The first of three installments of the results of the survey, which garnered 268 responses, focuses on demographic information and opinions about outdoor lighting. Future installments will look at safety and technology.
The first batch of results indicates that respondents share the concerns of the committee. Almost 80% of respondents thought that having light on all night is not helpful, 90% thought having lights on all night impacts wildlife, and 71% thought having lights on all night does not make residents safer.
The majority also said from a neighbor’s property bothered them. Eighty precent or respondents said lights from neighbors were visible from their homes and 64% said they experienced “light trespass,” where artificial light spills beyond the intended property and into neighboring properties or natural areas. Additionally, respondents frequently identified institutional properties as sources of excessive lighting.
However, many who took the survey stressed that some outdoor lighting remains important to help prevent falls on uneven or icy surfaces, navigating long driveways, personal security when arriving home, and visibility around parking lots and transit areas.
The survey discussion also acknowledged that the study had several limitations. Participation was voluntary, meaning self-selection bias is possible, the report noted. Also, the findings were based on participants’ self-reported perceptions rather than objective measurements. “Consequently, the results should be interpreted as reflecting residents’ experiences and perceptions rather than direct assessments of lighting levels or environmental conditions,” the report said.
