Gel Lee vs Rosco Equivalent Crossref Lookup

Filter actual caller Lee/Rosco crossreference measurements by source and same-reference color-distance ceiling; no invented proprietary equivalences, spectral match or identical rendition under another lamp.

Description

Gel alternatives can be screened using measured color distance under the same reference illumination.

Gel alternatives can be screened using measured color distance under the same reference illumination. Similarity is not spectral equivalence.^[1]

Enter aligned nonempty nonblank source/target IDs and nonnegative DeltaE/max, with a query present in the source list. Return candidate targets/distances sorted ascending, ties by row order; repeats are preserved.

When to use Gel Lee vs Rosco Equivalent Crossref Lookup

Use Gel Lee vs Rosco Equivalent Crossref Lookup when you need to evaluate the supplied records under the calculation and evidence rules below. No proprietary crossreference, spectrum or rendition under another lamp is inferred.

Prepare the actual venue, production, inventory or financial records requested. Confirm units and supply applicable local limits or verified catalog values.

How to use Gel Lee vs Rosco Equivalent Crossref 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 callerSourceGelIds, callerTargetGelIds, measuredSameReferenceDeltaE, requestedSourceGelId, callerMaximumCandidateDeltaE using the field table and calculation rules, then run the tool.
Read callerCandidateTargetGelIds, candidateMeasuredDeltaE. 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
callerSourceGelIds	Caller source gel ids	list of string	Required
callerTargetGelIds	Caller target gel ids	list of string	Required
measuredSameReferenceDeltaE	Measured same reference delta e	list of number	Required
requestedSourceGelId	Requested source gel id	string	Required
callerMaximumCandidateDeltaE	Caller maximum candidate delta e	number	Required

candidates=exact source match AND measuredDeltaE≤maximum

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
callerCandidateTargetGelIds	Caller candidate target gel ids	list of string
candidateMeasuredDeltaE	Candidate measured delta e	list of number

Limitations and assumptions

No proprietary crossreference, spectrum or rendition under another lamp is inferred.

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. Extremely large text inputs are rejected. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors.

Alternative or Complementary methods

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. For a complementary task, use Gobo Pattern Size A Size B Lookup: Gobo fit requires a holder-specific outer diameter and image aperture. Trade-size labels alone are insufficient.
