Measure description
Measured with utils/measure script using 2 identical lamps in parallel (MULTIPLE_LIGHTS=true, NUM_LIGHTS=2), reported values are per lamp, because a single E14 lamp draws below the Shelly Plug S Gen3's 0.1 W resolution. A preheated resistive dummy load (~8.5 W, thermally settled) was connected in parallel and its calibrated baseline subtracted: without it the hs sweep aborted on repeated 0 W readings at low brightness with saturated colors, where both lamps combined draw under 0.1 W. The lamp is multicolor (supported_color_modes: color_temp, hs), both modes were measured. Brightness starts at 2. At the darkest, most saturated hs points the per-lamp figure is coarse, limited by the meter resolution, but the absolute error there is well under 0.1 W. Matter device via the Matter integration.
