One side of this comparison rests on a reported figure. LEDI Scout SW20 is published by the manufacturer and corroborated across independent lookups, but we have not yet read the figures page-in-hand the way we have for the rest of the table. The comparison is shown because it is still the best available, not because it is settled. The manufacturer states a draw of 180–220 W; the midpoint is used, matching how we treat published output ranges. How we source figures.
