Landscape Lighting and Hamptons Dark Sky Compliance
Is Your Landscape Lighting Compliant With Hamptons Dark Sky Laws?
Landscape lighting that once seemed acceptable can attract concern after fixtures shift, plants are removed, lamps are replaced with brighter LEDs, or a neighboring property changes. A system may also have been designed without sufficient attention to shielding, glare, property lines, or operating hours.
Correcting landscape lighting that is not compliant with Dark Sky laws does not necessarily mean removing it. The solution may involve better aiming, shielding, lower output, revised controls, relocation, or selective fixture replacement.
What Dark Sky compliance is trying to accomplish
Outdoor lighting rules generally seek to reduce:
Light trespass across property lines
Direct glare
Excessive brightness
Unnecessary uplight
Lighting that remains on when it is not needed
Interference with the character of the night sky
The design objective is closely aligned with thoughtful landscape lighting: illuminate the intended subject while keeping the source discreet.
Southampton considerations
The Town of Southampton’s residential guidance says fixtures generally must be fully shielded, subject to stated exceptions. It also addresses placement, mounting heights, glare, light trespass, and operating hours. The Town’s guidance states that nonessential decorative or landscape lighting should not remain continuously on from 10 p.m. to dawn. It also identifies re-lamping, re-aiming, shielding, relocating, retrofitting, removing, or replacing as potential methods of addressing nuisance lighting.
East Hampton considerations
The Town of East Hampton’s residential lighting guidance emphasizes fully shielded fixtures, downward-directed light, and preventing the visible light source from affecting areas beyond the property line. Specific treatment can depend on the type of light and when the building was constructed.
Municipal codes and interpretations can change. The current requirements for the property’s exact town, village, project type, and installation date should be confirmed before making compliance claims.
Signs the lighting should be evaluated
A review may be appropriate when:
A neighbor can see a bright lamp or LED source
Beams extend beyond the property
Fixtures produce glare from roads or walkways
Uplights miss their trees and illuminate the sky
Floodlights are aimed too horizontally
Decorative lighting remains on throughout the night
Replacement lamps are substantially brighter than the originals
New landscaping has changed how light is contained
Fixtures near boundaries illuminate adjacent properties
How a system can be corrected
A Dark Sky retrofit may include:
Re-aiming fixtures more precisely
Adding glare shields or louvers
Lowering fixture output
Selecting narrower beam spreads
Relocating fixtures away from boundaries
Replacing exposed-source fixtures
Revising schedules or astronomical controls
Removing unnecessary layers
Converting broad floodlighting into focused illumination
Rebalancing the design after changes are made
The most successful corrections do more than reduce output. They improve visual hierarchy so the property requires less light to feel complete.
Compliance and beauty are not opposites
Dark Sky design favors restraint, precision, and concealed light sources—all qualities that support sophisticated outdoor lighting.
A well-designed property does not need to announce every fixture. Paths remain comfortable, entrances are legible, trees and architecture retain depth, and outdoor rooms feel inviting without competing with the night.

FAQs
Can existing lighting be made Dark Sky compliant?
Often it can be improved through re-aiming, shielding, dimming, controls, relocation, or selective replacement.
Are all uplights prohibited?
Requirements vary by municipality, property, fixture, and application. Confirm the current code for the exact location. Location specific blog posts are published here.
Can HLL guarantee code approval?
HLL can design and repair with the applicable requirements in mind, but the governing municipality is the final authority.
