Investigation summary
Illustrative evidence status: limited. The sample meter log favors lamp A under one test condition, but the figures are not comparable enough to establish a general claim. A useful investigation can end with an open question.
SYNTHETIC EXAMPLE / NOT A LIVE INVESTIGATION
Every measurement, excerpt and source below is invented for this demonstration. This is an abbreviated illustration of report sections, not a saved customer case or proof of engine accuracy. Actual results depend on the question and available evidence.
Illustrative evidence status: limited. The sample meter log favors lamp A under one test condition, but the figures are not comparable enough to establish a general claim. A useful investigation can end with an open question.
Power consumption and equal brightness are different measurements. Compare brightness, settings, duration and meter calibration before drawing a broader conclusion.
Repeat measurements at matched brightness with a calibrated meter and record the conditions for both lamps.
Were both lamps equally bright? Were settings and duration matched? How variable are repeated readings?
A completed case can show the excerpts checked, claim support decisions and withheld findings. In this illustration, the broader statement “A always uses less energy” would be withheld because these excerpts do not establish it.
Automated excerpt checks can miss errors. Source labels do not certify accuracy or peer review; inspect original context before relying on a finding.
Illustrative excerpt: “Trial 1: lamp A, 8 W; lamp B, 10 W. Brightness not recorded.”
Illustrative excerpt: “Lamp A: 11 W at a different brightness setting. No matching reading for lamp B.”
