CoachAssuming the lamps are plugged into a 60 volt outlet, the 40 W lamp has more resistance. This can be shown mathematically:
Resistance= V2/P=602/40=3600/40=90 ohms (40 Wlamp)
Resistance= V2/P=602/60=3600/60=60 ohms (60 Wlamp)
This shows that 40W lamp has more resistance than a 60W lamp.
Did you buy it in Europe or in North America ?
In North America, it's expecting to be powered by 120 volts.
In most of the rest of the world, it expects 240 volts.
120 volts, 60 watts:
P = E2 / R
R = E2 / P = (120)2 / 60 = 240 ohms
240 volts, 60 watts:
R = E2 / P = (240)2 / 60 = 960 ohms.
Yes, it consumes about 33% less provided both bulbs are of the same type. It consumes less because the current is less.
AnswerThe power of a lamp, in watts, is the rate at which it consumes energy -so, obviously, a 40-W lamp will consume less energy over a given period of time than a 60-W lamp -in the same way as you will travel less far at 40 km/h than you would at 60- km/h!

Can I use a 60 watt bulb in a 75 watt bulb ceiling fan?
Yes.
How can a 60 watt bulb use the same power as a 60 watt bulb can in a second?
A 60 watt bulb uses 60 watts of power continuously per second. It is consistent with the definition of power, which is the rate at which energy is consumed or produced. Therefore, a 60 watt bulb would use the same amount of power as another 60 watt bulb within the same timeframe of a second.
What size fluorescent bulb replaces a 60 watt incandescent bulb?
A 13-15 watt compact fluorescent bulb (CFL) or a 9-11 watt LED bulb is roughly equivalent to a 60 watt incandescent bulb in terms of light output.
What is the different between a 100 watt bulb and a 60 watt bulb?
40 watts of consumed power. The light output may be greater with one compared to the other, but wattage alone does not give us that information. Electric heaters, for example, consume 1500 watts of power and produce almost no visible light.Check the Lumen's. That is where the difference is.Current draw and light output.A 60 watt bulb uses 60 watts of electricity (i.e. it converts 60 joules of energy per second), a 100 watt bulb converts 100 joules per second. Electrical power is measured in watts. Since a 60 watt bulb pulls less energy to it than a 100 watt bulb the 60 watt bulb will not be as bright.Resistance.Just in the amount of power used and the brightness of the bulb. The 60 watt bulb might be a bit smaller.
Does 660 watt socket use a 60 watt bulb?
Yes, a 660 watt socket can safely handle a 60 watt bulb. The wattage rating of a socket indicates the maximum amount of power it can handle, so a 60 watt bulb is well within the safe range for a 660 watt socket.
