What are the different types of moving lights?

Moving lights fall into five main categories based on their beam characteristics and intended use:

Spot (or Profile): Produces a sharp-edged beam with gobo wheels for pattern projection, an iris for beam sizing, and often framing shutters for precise beam shaping. Used for highlighting specific objects, follow-spot applications, and projecting textures onto surfaces.

Wash: Has a soft edge and is designed to light large areas with even, blended color. Wash fixtures don't have the precision beam control of spots but cover more area. 

Beam: Produces a narrow, laser-like column of light through the air. Beam fixtures are typically used in live events for dramatic aerial effects rather than for illuminating surfaces. Their non-tapered beam is visually distinct from spots and washes.

Hybrid: Combines spot, wash, and beam capabilities in a single fixture. Hybrids are versatile multi-purpose fixtures, but they won't outperform a dedicated spot, wash, or beam fixture in any single category. They're popular when budget or truck space is tight and the rig needs to serve multiple roles.

Effects (EFX): A broad category for fixtures with individual pixel control, continuous 360° pan and/or tilt, or unique built-in visual effects. These fixtures are used when you want the audience to see the fixture itself as a visual element, not just its output.
