WebSep 3, 2024 · A quick search finds incandescent efficiency in the range, at best, of 5% to 10%. If a 100W incandescent bulb is 10% efficient (very optimistic) then 90% of the power - 90W - is lost as heat. If the 15W LED produced entirely heat and no light at all (which wouldn't be too useful), it would only produce 15W of heat. No contest.
