What is the LED equivalent of 40W?
Compare wattage
| Traditional bulb1 | Halogen2 | LED |
|---|---|---|
| 40 watts | 25 watts | 5 watts |
| 60 watts | 40 watts | 7 watts |
| 75 watts | 45 watts | 9 watts |

How many lumens is a 40 watt CFL bulb?
460 lumens
Wattage to Brightness Comparison A 40 watt incandescent filament bulb produces roughly 460 lumens. An equivalent compact fluorescents (CFL) bulb in light output (lumens) should consume only around 7 watts and LEDs approximately 6 watts.
What is a 40 watt CFL bulb equivalent to?
Know your watts and lumens (light output)
| Incandescent | CFL | Lumens |
|---|---|---|
| 40W | 11-12W | >490 |
| 60W | 13-18W | >900 |
| 75W | 19-22W | >1,200 |
| 100W | 23-26W | >1,750 |

How many lumens does a CFL light bulb use?
CFLs and LEDs use much fewer watts than incandescents with the same brightness. As a rule, you’ll replace a standard 75-watt bulb with an energy-saving bulb of about 1100 lumens. On the low end, replace a 40-watt bulb with an energy-saving bulb of about 450 lumens.
Which is more energy efficient CFL or led?
While the math for the CFL bulbs is simple, the LED bulbs are even more energy-efficient and durable than compact fluorescent light bulbs. LEDs require less wattage than CFL for the same amount of light.
How many lumens does a LED bulb use?
Some of the most energy to light efficient LED bulbs are now reaching over 120 lumens in Energy Star tests. A 40 watt incandescent filament bulb produces roughly 460 lumens. An equivalent compact fluorescents (CFL) bulb in light output (lumens) should consume only around 7 watts and LEDs approximately 6 watts.
How many lumens does a 40 watt incandescent bulb produce?
A 40 watt incandescent filament bulb produces roughly 460 lumens. An equivalent compact fluorescents (CFL) bulb in light output (lumens) should consume only around 7 watts and LEDs approximately 6 watts.
