How many watts should a 40w bulb use at 120v?
Naty1 said:That's a power use figure, like one on a frig or work tool...it's not an indicator
of how much light it produces...
As previously stated, forty watts at the voltage specified by the manufacturer.cmb said:Hence the question "How many watts should a 40w bulb use..."

Due to a variety of factors, the measured power consumption will vary from the advertised value.
The power output of a 40w bulb when used at 120v is 40 watts.
The voltage directly affects the power output of a 40w bulb. When the voltage is increased, the power output also increases and vice versa.
The energy consumption of a 40w bulb when used at 120v is 40 watt-hours (Wh).
No, it is not recommended to use a 40w bulb at a higher voltage as it can cause the bulb to overheat and potentially lead to a fire hazard.
The lifespan of a 40w bulb when used at 120v can vary depending on the specific bulb and usage, but on average it can last for about 1,000 hours.
