| Old claim | ~Lumens | Typical LED watts |
|---|---|---|
| 40W equiv | ~450 lm | ~4–6 W |
| 60W equiv | ~800 lm | ~8–12 W |
| 75W equiv | ~1100 lm | ~11–15 W |
| 100W equiv | ~1600 lm | ~15–20 W |
Equivalence is lumens
Ignore "60W LED" stickers that skip the lumen line. Efficacy varies. Color bulbs and high-CRI lamps often need more watts for the same light.
