Definitions of Outdoor Lighting terms as used by NightVision Outdoor Lighting in Canton, GA. 22 terms defined.
An astronomic timer calculates local sunrise and sunset times based on geographic location and date, adjusting lighting schedules automatically throughout the year. Unlike a basic timer, it never needs seasonal reprogramming. It ensures outdoor lighting activates consistently at dusk, no matter the time of year.
Beam spread describes how narrow or wide the light emitted from a fixture is, measured in degrees. Narrow spreads around 15 degrees are used to accent tall trees or columns, while wider spreads over 60 degrees wash walls or foliage. Matching beam spread to the subject is key to professional results.
Brass fixtures are landscape lights constructed from solid brass, a durable metal that resists corrosion and develops a natural patina over time. They typically outlast aluminum or plastic alternatives, making them a popular choice in humid or high-moisture climates. Most premium landscape lighting systems use brass or copper components.
Color temperature measures the warmth or coolness of a light source in Kelvin (K). Landscape lighting typically ranges from 2700K, a warm inviting glow, to 3000K, a slightly crisper white. Choosing the right temperature affects the mood and how plants, stone, and architecture appear at night.
Dark sky compliant fixtures are designed to direct light downward and minimize light pollution that brightens the night sky. They use shielded housings and controlled beam angles to reduce glare and skyglow. This approach preserves views of the stars while still providing effective outdoor illumination.
Downlighting positions fixtures above a subject and directs light downward to illuminate patios, walkways, or garden beds. When mounted in trees or eaves, it produces a natural, sunlight-like effect. This method is ideal for functional lighting in outdoor living spaces and entertainment areas.
Grazing is a lighting technique where fixtures are placed very close to a textured surface, such as stone, brick, or bark, and aimed nearly parallel to it. The sharp angle emphasizes surface texture through dramatic highlights and shadows. It is commonly used on stacked-stone walls and columns.
The hub method is a wiring approach where multiple fixtures connect to a central junction point rather than being daisy-chained in series. Each fixture receives a nearly equal amount of voltage, producing uniform brightness. This layout also simplifies future troubleshooting and system expansion.
A lighting maintenance plan is a scheduled service program that includes fixture cleaning, realignment, bulb replacement, wire inspection, and seasonal adjustments. Regular upkeep prevents dim spots, misaimed fixtures, and premature system failure. These plans help protect the long-term performance and appearance of an outdoor lighting investment.
Lighting zones are groups of fixtures wired or programmed together so they can be controlled independently from other groups. Common zones include the front facade, backyard patio, pool area, and pathways. Zoning allows homeowners to adjust brightness or schedules for specific areas as needs change.
Low-voltage lighting operates at 12 volts rather than standard 120-volt line power, using a transformer to step down the current. This makes it safer to install, more energy efficient, and easier to adjust over time. It is the industry standard for residential landscape lighting systems.
Lumens measure the total amount of visible light a fixture produces, replacing wattage as the primary brightness metric for LED lighting. Landscape fixtures generally range from 100 to 800 lumens depending on their purpose. Selecting appropriate lumen output prevents overlighting and preserves nighttime ambiance.
Moonlighting is a landscape lighting technique where fixtures are mounted high in trees and aimed downward to mimic the soft, dappled glow of natural moonlight. This creates gentle shadows on the ground below through branches and leaves. It is often used to add ambiance to patios, lawns, and gathering areas.
Path lighting refers to low-level fixtures installed along walkways, driveways, and garden borders to illuminate ground surfaces for safety and visual guidance. These fixtures typically cast a soft downward glow to prevent glare while highlighting the edges of paths. They are a staple of most residential landscape lighting designs.
A photocell is a light-sensitive sensor that automatically turns a lighting system on at dusk and off at dawn. It removes the need for manual switching and adjusts to seasonal daylight changes. Photocells are often paired with astronomic timers for precise control of outdoor lighting.
Shadowing involves placing a fixture in front of an object and casting its shadow onto a nearby wall or fence. This technique adds movement and interest as breezes shift the shadow patterns. It is often used with textured plants like Japanese maples or ornamental grasses.
Silhouetting places a light source behind an object and aims it toward a wall or backdrop, creating a dark outline against a lit surface. This technique is used to feature ornamental plants, sculptures, or unique tree shapes. It adds artistic contrast and depth to landscape designs at night.
Smart lighting control lets homeowners manage outdoor fixtures through a smartphone app, voice assistant, or home automation system. Features often include dimming, color tuning, scheduling, and zone control. This technology enables custom scenes for entertaining, security, or holidays without touching the transformer.
A transformer is the component that converts a home's 120-volt electricity into the 12 volts needed to power low-voltage landscape lighting. Quality transformers include timers, photocells, and multiple taps to compensate for voltage drop across long wire runs. Sizing it correctly is critical to system performance.
Uplighting involves placing fixtures at ground level and aiming them upward to highlight architectural features, trees, or columns. This technique emphasizes vertical elements and creates dramatic shadows and depth after dark. It is one of the most common methods for showcasing home facades and specimen trees.
Voltage drop is the gradual loss of electrical power that occurs as current travels along a wire, resulting in dimmer fixtures farther from the transformer. Proper wire gauge, hub layouts, and multi-tap transformers are used to minimize this issue. Managing it ensures consistent brightness across every fixture.
Wash lighting uses wide-beam fixtures to cast a broad, even layer of light across a surface such as a wall, hedge, or fence. The technique softens architectural features and eliminates harsh shadows. It is often paired with accent lighting to create balanced, layered outdoor scenes.
