Scope and starting point
Long-term flux-maintenance projection from suitable LM-80 data; a projection is not a field failure-rate study.
Selection notes
Check the exact color bin, drive current, junction temperature and footprint. Package dimensions are not the light-emitting surface. Compare flux or efficacy only at equivalent current, temperature, CCT and CRI; confirm soldering and optical compatibility separately.
Keep a reproducible record
Save the complete part number, source revision, operating point and the reason for each decision. Keep calculated examples separate from observed results. A measurement report needs its sample identifier, instrument and calibration details, stabilization, ambient conditions, raw record and uncertainty statement. Do not replace a missing value with zero or a typical value with a guaranteed limit.
