DELTA Portfolio
	DELTA Portfolio: Highway Rest Areas DELTA evaluated the exterior and interior lighting at the newly expanded Clifton Park Rest Area on the I-87 Adirondack Northway in Upstate New York. The facility, which is open 24 hours a day, has parking, picnic areas, a dog walking area, and a pavilion. Inside the pavilion are a tourist information counter, restrooms, vending machines, and a State Police Station. This publication describes the lighting, discusses the public's reaction to the lighting, and quantifies the energy savings and environmental impact of the lighting.
DELTA Snapshots
	DELTA Snapshots: Electrodeless Lighting Electrodeless lamps can reduce relamping requirements and improve color rendering in exterior environments. This project retrofits the lighting system in Union Square Park in New York City. A New York State utility replaced the old system, which used 100-W high-pressure sodium lamps, with an electrodeless fluorescent lamp system that reduces relamping frequency and improves color rendering and visibility of people in the park.
	DELTA Snapshots: Gas Station Canopy Lighting The recent trend toward increasingly bright lighting for gas station has caused drivers, residents of surrounding areas, and local officials to complain about excessive glare and light trespass. This Snapshot shows how gas stations can provide satisfactory light levels for their customers at night while reducing glare and light trespass. Other lighting objectives included attracting customers, helping customers feel safe, and making the station visible from a distance.
	DELTA Snapshots: Outdoor Entry Lighting Carefully selected outdoor luminaires can reduce energy use, improve lighting quality, and provide a sense of security for homeowners. This Snapshot shows how changes to the outdoor entry lighting improved the appearance and security of a row house in a historic neighborhood in Albany, New York. Lighting objectives in this installation included eliminating dark areas on the entry stoop, making it easier to see the lock at night, reducing glare, providing light at dusk without leaving lights on all day, and reducing energy use.
Field Test DELTA
	Field Test DELTA: Photovoltaic Lighting Retrofit Kit for Bus Shelters The DELTA research team field tested an installation of a photovoltaic (PV) lighting retrofit kit for bus shelters on Long Island, N.Y. This solar-powered system provides a backlight for large advertising signs. PV cells charge an array of batteries, eliminating the need for an external electricity supply. This field test evaluated the system's performance over an extended period of time and gauged public reaction to the system at night.
