Beam Distribution (how big or spread out the light is)

Beam distribution refers to the physical spread of light as it travels through space. It describes where the light goes, how wide it becomes, and how concentrated it remains over distance. This is determined by the internal optics of a fixture, primarily the lens and reflector, and it remains independent from any patterns or textures added later.

• Tight Focused
  A very narrow, concentrated beam with minimal spread, designed to isolate a small, precise area. This type of distribution is used when control and separation are required, such as highlighting a single subject without lighting the surrounding space.

• Parallel Beam
• A highly collimated beam that maintains nearly the same width over distance with almost no divergence. Unlike a typical focused beam that gradually expands, this distribution remains consistent, making it useful for long-throw applications or visual effects where the beam itself is meant to be visible in the air.

• Round
  A symmetrical circular beam with even spread in all directions from the center. This is the default expectation of most light sources and serves as a baseline distribution when no directional distortion or shaping is applied.

• Scatter
  A wide, uncontrolled spread where light disperses broadly with low concentration and soft edges. Instead of directing attention to a specific point, this distribution fills space, often reducing contrast and creating an ambient environment.

• Medium Scatter
  A moderately diffused beam that spreads wider than focused light but retains some central intensity. It sits between precision and coverage, providing visibility without completely losing directional emphasis.

• Overhead
  A downward-directed beam originating from above, defined by orientation rather than shape or spread. While the beam itself may still be narrow or wide, the defining characteristic is its vertical angle, which influences how surfaces and subjects are perceived.

Beam distribution, taken alone, answers a structural question. It defines the footprint of the light. It does not yet define its character.

Optical Effects (what the light looks like)

If beam distribution is about where the light goes, optical effects describe what happens within that beam. These effects modify the internal structure of the light, introducing patterns, asymmetry, or visual complexity. They are created through additional optical components such as gobos, prisms, or specialized lens systems.

• Star Focused
  A sharply defined star-shaped pattern with distinct points radiating from a central focus. This effect introduces clear geometry into the beam, making the light itself a visible design element rather than just a source of illumination.

• Comet
  A directional beam with a bright leading point and a trailing gradient that suggests motion. The asymmetry creates a sense of direction, even when the light is static, making it visually dynamic.

• Jellyfish
  A soft, radial pattern with flowing, irregular extensions resembling organic movement. Unlike geometric patterns, this effect produces a more natural, fluid appearance within the beam.

• Pear
  An asymmetrical beam wider at one end and narrower at the other, forming a teardrop-like distribution. This shifts visual emphasis off-center, which can subtly guide attention in a specific direction.

• Three Lobe Umbrella
  A beam divided into three rounded segments that expand outward evenly from a central point. Each lobe maintains similar intensity, creating a balanced but segmented distribution.

• Three Lobe Vee
  A three-part beam arranged in a V-shaped orientation with directional separation between lobes. Unlike the umbrella variation, this configuration introduces a clear directional bias.

• Umbrella
  A broad, domed distribution that expands outward uniformly, resembling a wide canopy. It softens transitions between light and shadow while maintaining a defined overall shape.

• X Arrow
• A sharply defined intersecting pattern forming an X with directional emphasis along its axes. The crossing lines create a structured, high-contrast visual.

• X Arrow Diffuse
  The same intersecting X structure with softened edges and reduced contrast between segments. The pattern remains visible but less rigid.

• X Arrow Soft
  A heavily blended version of the X pattern where lines are smooth and transitions are gradual. At this level, the structure becomes more suggestive than defined.

Optical effects do not change how far the light travels or how wide it spreads. They change how the light appears within its existing boundaries. A narrow beam can contain a complex pattern. A wide beam can remain completely uniform. These are independent controls layered on top of one another.

Non-Projective and Installation-Based Lighting Types

Not all lighting systems are designed to project a shaped beam. Some are built to provide general illumination, guide movement through space, or integrate into architectural environments. These types are often grouped incorrectly with spotlight behaviors, even though they operate under different principles.

• Bollard
  A fixed, low-height outdoor fixture designed for ground-level illumination rather than directional projection. It is typically used along pathways or landscapes to provide visibility and orientation.

• Top Post
  A pole-mounted fixture configuration where the light source is positioned at the top for area coverage. Its purpose is distribution over space rather than focus on a specific target.

• Area
  A broad illumination category intended to evenly light large spaces without defined beam shaping. Instead of producing a visible beam, it creates an overall level of brightness across an environment.

These types do not rely on beam shaping or optical patterning. Their goal is coverage, not precision. Including them in a broader taxonomy clarifies an important distinction: not all lighting is about directing attention. Some of it is simply about making space usable.
