How to Determine the Followspot You Need for Your Space

A followspot that works well from the back of a school auditorium may not be right for a long arena throw. Before comparing models, record where the operator will be positioned and roughly how far the beam must travel. Those two details give you a much better starting point when comparing Canto USA followspots.

Step 1 — Decide Placement and Measure Throw Distance

Start by deciding the intended mounting or operator location: booth, back of house, catwalk, dedicated followspot platform, or a portable tripod/stand. Throw distance is the straight-line distance from the followspot lens to the farthest point onstage that needs to be lit.

• Measure straight-line distance with a laser measure where possible.
• If you must measure horizontally and vertically, record both and convert to a straight-line distance (Pythagorean theorem) or use a laser for accuracy.
• Note any obstacles, windows, or glass between the followspot and stage—glass can reduce usable output and introduce reflections.

Record the shortest and longest distances the followspot must reliably reach—the longest distance typically determines required output.

Step 2 — Determine the Light Output You Need

Talk with your lighting designer or technical director to set target illumination (footcandles or lux) for your performance or service. Compare those targets against manufacturer photometrics to determine whether a fixture will deliver the required light at your measured throw distance.

For side-by-side comparisons, use real-world photometric data. See Canto USA Provides Real World Photometrics for measured output examples at different distances.

Step 3 — Choose the Lamp Type

Followspots commonly use tungsten, MSR, or LED sources. Consider how the chosen source will integrate with your venue’s overall lighting (color temperature, dimming behavior, and beam quality). If matching older fixtures is important, check color rendering and white balance with your lighting designer.

Canto USA followspots are modular and designed to be upgradeable, offering flexibility as venue needs change.

Step 4 — Check Available Power and Electrical Requirements

Confirm the voltage, circuit capacity, and connector type at the followspot location before specifying a model. Some followspots have higher inrush or steady-state current requirements—your venue electrician should verify that the available circuit(s) can support the fixture(s).

Record the available breaker size, outlet type, and any local limitations so you can match those to a followspot model’s requirements during specification.

Step 5 — Think About the Operator and Ergonomics

Operator comfort and sightlines affect performance. Consider mounting height, rail or platform design, handrail positions, and how the operator will access the unit for extended use. Also plan for routine service access.

Canto USA followspots are designed with operator ergonomics in mind. For technique and operation guidance, review The Art of Followspot Operation — Canto USA Followspots.

Quick Decision Checklist

• Operator position and mounting type chosen?
• Measured longest throw distance recorded?
• Target onstage illuminance (footcandles/lux) specified?
• Power availability and connector verified by electrician?
• Required lamp/source type and compatibility with house lighting considered?
• Operator sightlines and maintenance access planned?

Replacement and Refurbishment Considerations

If you’re replacing older equipment, a refurbishment or retrofit may be an option. See our example project at Starpoint Central School District to compare replacement versus refurbishment outcomes: Followspot Refurbishment at the Starpoint Central School District.
