Measure description: Uses the measurement data of sylvania/40A19FILCCLWIFI. SYLVANIA ships one lamp in three glass shapes (A19, G25, ST19) with identical electrical specs, the same FCC ID, and a byte-identical firmware image, so the filament and the power readings are the same. Only the Tuya product id differs, one per SKU. The ST19 was not measured separately.
LUT curve quality: 98.7 · Excellent
