A town known for its lights has a particular reason to think about night lighting. Portland Head Light in Fort Williams Park and the active eastern tower at Two Lights define the shoreline after dark, and many homes look out over the same water. Shielded, downward-aimed fixtures light steps, paths and driveways without spilling glare over the water or into neighbors’ windows. Warm color temperatures and dusk-to-dawn or motion controls give security without leaving floodlights burning all night, and low-voltage LED landscape lighting brings out plantings and stone walls with little energy. Long driveways and walks from the road benefit from a few low bollards or path lights rather than one bright pole light, which keeps the night sky darker for everyone.
Salt air is the other factor. Outdoor fixtures along the shore corrode quickly, and standard painted aluminum and steel hardware can fail within a few seasons. Solid brass, copper or 316 stainless housings, rated for wet locations and mounted on gasketed boxes, outlast them by years. The same goes for outdoor receptacles, which need weather-resistant GFCI devices and in-use covers. Buried cable for landscape lighting and post lights should be run at the proper depth and protected where it enters the ground, since frost heave and salt both work on it over time. Timers and photocells should be mounted where spray and snow will not bury them, and a GFCI device protecting landscape transformers keeps a wet winter from turning into a tripped circuit nobody notices until spring.
Indoors, older homes with plaster ceilings are good candidates for slim LED wafer lights that need little ceiling depth, while mid-century and later homes can take recessed lighting, under-cabinet strips, dimmers matched to LED loads and smart controls. Ceiling fans need boxes rated to support them. An LED retrofit also ends the heat buildup that browns old glass globes and cooks their sockets. From a single porch light to a whole-house lighting plan with dimming scenes, Goodnow Electric handles the fixtures, fans and controls and files any new circuits with Cape Elizabeth Code Enforcement.
