Beam Configuration

Beam configuration is produced by focusing and/or diffusing the light from an LED’s landscape lighting fixture, and it includes (1) the angle of the cone of light emitted, which can be narrow, medium or wide; (2) light distribution within the light cone, which can be bright in the center and dimmer elsewhere, or the reverse, or extremely even throughout the cone. Light distribution can also include irregularities — hot spots, dark rings, or bright rings — caused by imprecise reflectors, improperly surfaced reflectors, or “adjustable focusing” that only re-arranges the beam’s defects.

Inferior landscape Lighting LED’s produce beams with dark or bright spots, which when projected upon a wall for instance can be a problem; or bright central “hot spots” that tend to seize your attention. Hard-edged beams, like those of theatrical spotlights, can lack the surrounding light necessary for peripheral illumination. This latter effect worsens under stress, when the brain concentrates on central images, and when people and objects seem to appear suddenly out of the dark, provoking an instinctive startle response.

In contrast, the superior beam configuration and adjustable control in Gambino LED landscape Lighting modules and fixtures results from light that is focused and diffused in a manner optimized for the particular application, such as close-range for dramatic effects, focal points that attract attention, or long-distance spotlight/t use, or somewhere in between. Diffusion or “smoothing out” of the beam is achieved by means of adding either tiny irregularities or a series of regular shapes into the surface of the optics focusing element.

A third method of diffusion is passing the light through a translucent optionally available frosted, spread or diffusor lenses, such as those available for our Gambino landscape Lighting LED modules.

Specification Data Sheet Overview:

The SD29A and SD30A Gambino landscape lighting LED module is the latest in LED technology featuring a modular design.  It enables the user to gain several advantages over the competition—field serviceability, reusable components, and design flexibility.  This designer/contractor-friendly module allows for quick and easy service changes should the need arise instead of disposing it in the landfill–drivers, lenses, and optics can be changed in the field as desired.

A leading feature of this LED module is its concealed 4-position switch, which allows the professional lighting designer/contractor to provide for varying lumen outputs.  Additionally, each module comes with 1 optic provided and there are 3 additionally available and are interchangeable, which allows for even greater design flexibility–up to 17-different measured outputs.  This result is a professional designer’s dream.

The aluminum anodized LED body acts to provide protection to all internal electronics and to serve as its heat sink.  This elegant and simple housing design is bright blue in color and it is larger than most competitor LED modules or retrofit units.  This is a distinct advantage in the heat transfer process and in enhancing the opportunity for extended life-span with greater lumen range.

This module out-performs the competition within the outdoor landscape lighting arena.  It has a high efficacy and lumen output per watt rating.  Power consumption ranges from 3.5-7 watts and lumen output ranges from 140-lm. to 410-lm on model Sd29A  and 4-12 watts and lumen ranges from 270-810 lumens on model Sd30A (depending upon switch position chosen).

Major Features:

  • Modular Component Design—highly manageable  and field-serviceable
  • Adjustable Driver—4-position switch to provide varying lumen outputs
  • Interchangeable Optics—15, 30, 45, or 60 degree beam angles
  • Enhanced Design-ability—up to 17 varying lumen output options by driver switch position and optics use
  • Cree chips (XB-D)—high quality, high efficacy, long-lifespan, and low light decay
  • High purity, aluminum anodized heat sink body
