No problem. The main thing to be sure of when you change a bulb is that the new bulb is not too high a wattage than your lighting fixture was designed to handle, so it won't get over-heated.
An electrical watt is a measure of power. A 40 watt light bulb uses 40 watts of electrical power. It has a relative measure of twice the light output of a 20 watt bulb and one half the output of an 80 watt bulb. A 40 watt bulb uses 40 Joules of energy each second, or 40 watt-hours of energy each hour. In 1000 hours it uses 40 kilowatt-hours or Units of electrical energy.
Bulb brightness in LumensA 100 watt Bulb is rated at approximately 1700 lumensA 60 watt incandescent bulb is rated at approximately 800 lumensA 40 watt bulb is rated at approximately 400 lumensA 25 watt bulb is rated at approximately 180 lumensA 4 watt night light bulb is rated at approximately 20 lumens
Yes if it fits. The 40 watts would be an upper limit.
The higher the wattage the more you pay for power. So it costs more to operate a 120 watt bulb than it does a 100 or 40 watt bulb.
You want to compare the lumens of the bulbs.

If it is a 40 Watt bulb it converts energy at the rate of 40 Watts as long as it is switched on.
No. It just draws less power.
They will last about the same period of time.
A 40 watt bulb is dimmer than a 100 watt bulb.
looking for a 40 watt g bulb what is that?
On this calculation I am assuming that the light bulb is using a 120 volt source. Watts = Amps x Volts. Amps = Watts/Volts, 40/120 = .33 amps. R = Volts/Amps, 120/.33 = 363.6 ohms resistance in the 40 watt light bulb.
40 watt light bulb. This is obvious. Go do an experiment. -_-

40 watt light bulb
It isn't more, it is less if bulbs are of the same type.
