Sylvania 40A19FILCCLWIFI

Originally measured with utils/measure script on 2024-01-28, with a Shelly Plug US from a bad batch that inflates power readings by a constant factor of 1.22x. Corrected on 2026-09-10 by dividing every LUT value and the standby power by 1.22. The correction factor was determined on 2026-09-06 on the sister profile sylvania/A19CCECWF, by remeasuring on a Sonoff S31 and cross-checking the bad Shelly Plug US against a Kill-A-Watt (1.22x at 1 W, 1.22x at 100 W, 1.20x at 950 W); this model was not remeasured. The corrected 8.05 W -> 6.60 W peak now sits underneath the lamp's 7 W rating. The G25 (40G25FILCCLWIFI) and ST19 (40ST19FILCCLWIFI) variants share this profile's data: SYLVANIA ships one lamp in three glass shapes 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 brightness.csv (added 2026-09-22) is not a new measurement: it simply averages the color_temp LUT's 499 and 500 mired readings (both the same fixed 2000K output), so the bulb can be an RGBCT with a fixed 2000K (localtuya) or an RGBW with white mode (ESPHome).
