Dimmer Curve Profile Linear S-Curve Lookup
Read actual caller measured dimmer control-to-light curve rather than inventing generic S-curve calibration; no voltage-power equivalence, lamp thermal response or console profile upload.
Description
A dimmer curve is a calibration between control and measured light output.
A dimmer curve is a calibration between control and measured light output. Generic profile names do not define every fixture’s response.1
Enter aligned fraction lists 0–1 and query fractions. When queried, at least two strictly increasing control points and nondecreasing outputs are required; queries must be in range. Return interpolated outputs; an empty query list is allowed.
When to use Dimmer Curve Profile Linear S-Curve Lookup
Use Dimmer Curve Profile Linear S-Curve Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No voltage-power equivalence, lamp thermal response or console profile upload is provided.
Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.
How to use Dimmer Curve Profile Linear S-Curve Lookup and understand its results
- Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.
- Enter callerObservedControlFractions, callerObservedLightOutputFractions, queryControlFractions using the field table and calculation rules, then run the tool.
- Read interpolatedMeasuredDimmerOutputs. The explanation below defines the units, signs, ordering and any flags or placeholder values.
- If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.
| Input field | Meaning | Value type; see rules below | Requirement |
|---|---|---|---|
| callerObservedControlFractions | Caller observed control fractions | list of number | Required |
| callerObservedLightOutputFractions | Caller observed light output fractions | list of number | Required |
| queryControlFractions | Query control fractions | list of number | Required |
Enter aligned fraction lists 0–1 and query fractions. When queried, at least two strictly increasing control points and nondecreasing outputs are required; queries must be in range. Return interpolated outputs; an empty query list is allowed.
output=piecewise-linear interpolation between measured controls Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

}Limitations and assumptions
No voltage-power equivalence, lamp thermal response or console profile upload is provided.
Numeric inputs, where present, must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Numeric lists are limited to 10,000 entries; string lists to 128 strings of at most 128 characters each. The rules above may impose smaller limits. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.
Alternative or Complementary methods
Use Iris Diaphragm Aperture Range Lookup: A measured iris-to-beam calibration can be inverted within the observed range. Throw conditions must match the calibration. For a complementary task, use LED Wash Par Can Replacement Equiv Lookup: Replacement lighting estimates need matched-area illuminance rather than wattage alone. Whole fixtures introduce rounding in both output and power.
