New Options For Lighting Design

Providing effective and useful exterior lighting without ruining the aesthetics of the landscape is one of the main challenges facing many designers. New technology for landscape lighting has enabled many innovative advances in lighting design. One such option currently being utilized by some designers is the use of retractable luminaries.

Retractable Lighting

Several manufacturers are currently producing lighting fixtures that can disappear during the daylight when not in use. Retractable lighting provides all the functional benefits of traditional exterior lighting without interfering with the landscape design. At night, the fixtures provide the necessary illumination for pathways and walkways. Yet, when they are not in use during the day, the fixtures are hidden in the ground. The Retractable Bollard from RUUD Lighting Inc, in Racine, Washington is one such light.

 All low voltage units from RUUD Lighting have a patented, pigtail connector which quickly attaches to their Luma After-Sunset(R) cable. This heavy-duty #10 gauge 3-wire (10/3) cable assures maximum run-lengths with minimal voltage drop. The cable attaches directly to their Luma remote Transformer, which is available in 300 watt and 600 watt models. Their retractable bollard (above) rises 13.1" when powered (below left), and retracts to grade level when not in use (below right).

The system uses a unique rack-gear system to extend and retract the bollard. When power is applied to the UL wet listed fixture, it energizes the system. First, the inner fixture rises from its shell (within 15 seconds or less), and rises 13.1 inches. Then the lamp itself lights up providing illumination.

Turning the system off retracts the fixture from the power provided by an internal long-life, nickel cadmium battery. Within 25 seconds or less, the fixture is gone from sight as it retracts into its PVC shell. The casing safely conceals and protects the fixture from grounds maintenance equipment and pedestrian traffic.

 RUUD Lighting offers three types of lights. From right to left, its Directional Accent Light is suitable for drawing attention to specific elements such as statuary, topiary, archways, or ground level signage; its Clear Path Light is suitable for casting pools of light along pathways or around low to medium height landscape areas; its Louvered Path Light is suitable for framing pathways and driveways or directing attention to grade-level landscape features.

The Retractable Bollard offers three optical styles in 12V and 120V models. The Clear Path Light Bollard uses up to a 50W MR16 lamp and is great for pathways or medium height landscape areas. The Louvered Path Light Bollard uses either an 18W T5 incandescent or a 13W fluorescent (12V only), and provides general illumination for pathways and grade-level features. Designers can accent topiary, statuary, and archways easily with the Directional Accent Light Bollard,which uses up to a 50W MR16 or a 13W fluorescent (12V only) lamps.

Pneumatic Light

Another exciting new technology has emerged that uses air as a power source for retractable motion. AirLight Systems Inc. in Danvers, Massachusetts, has introduced the world's first and only pneumatic landscape light.

Powered by compressed air, the light fixtures remain below ground during the day and rise 12î for evening illumination. The AirLight Systems contains a control unit with a mini compressor, a transformer, and a timer.

The AirLight 12-12 fixture itself is constructed of heavy duty ABS plastic. The fixture contains one inner hollow piston encased within a housing. The inner piston has a halogen lamp enclosed at top by a Lexan lens, which offers consumers the ability to switch styles and colors from the lens accessory product line.

The fixture is complete with wire pigtails form the bottom and an air inlet on the side for easy installation. The installation process developed by AirLight Systems parallels that of an irrigation systems. Along with running wire to each light, an air pipe must also be run from the controller to the AirLights.

Retractable lighting is another option is the long list of new technologies available for Landscape Architects and their clients. LASN

 The AL-108 is the controlling unit behind the AirLight System. It plugs into any 110-volt outlet and contains everything necessary to run up to 20 AirLights (left and above). The mini compressor creates the force to bring the lights up and maintain their posture, while the timer allows the consumer to customize their unit. The system also allows for easy lens accessibility (below).
