Any electric lamp should use the amount of energy that is stated somewhere on its body in watts. That wattage could be printed on the glass bulb or on its metal cap and/or on the box it was sold in.
It does not matter if it's an infrared type or any other type of bulb, the wattage it was designed to take is the wattage it should use.
So a 125 watt infrared bulb should use 125 watts of energy.
If the question is really asking how much it costs to run that bulb, then the answer depends entirely on two things:
- the time the bulb is in use
and
- the cost that you have to pay for electrical energy in your locality.
The cost is charged in cents per kilowatt-hour. It may vary according to the time of day or night, depending on the supply service you subscribe to.
If the cost in your area is, say, 15 cents per kilowatt-hour, then running a 125 watt lamp for 2 hours would cost you (125 x 2 x 15) / 1000 = 3.75 cents.
What else can I help you with?
A 100 watt light bulb converts electrical energy into electromagnetic energy at a slower rate that a 40 watt light bulb?
The higher the wattage, the more electrical energy is being used. In a light bulb the electrical energy is converted to EM energy which appears in both visible and infrared parts of the spectrum, so the answer is no, it will be at a higher rate for a 100 watt bulb
What uses more energy a 60 watt light bulb or 18 watt light bulb?
This depends on how long it is being used. The 60 Watt bulb consumes 2.6667 times the power of an 18 Watt bulb, but energy equals power times time. There is also an amount of 'hidden' energy: the energy to manufacture and transport the bulb. This depends on how long it is being used.

Compare and contrast a 60 watt and 100 watt light bulb?
The more energy that is transferred in a certain time, the greater the power. A 100W light bulb transfers more electrical energy each second than a 60W light bulb.The equation below shows the relationship between power, potential difference (voltage) and current:power (watts) = current (amps) x potential difference (volts)
How you can calculate how much energy is used by a light bulb?
from its power if it is 100 watt so it produces 100 joule per second but this includes all energy produced by the lamp (light/heat energy) Their is a formula E=h x v, E=energy, v=frequency, and h=the constant I think
What does 40 watts bulb mean?
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.

How much energy does a nightlight use compared to a 100 watt bulb?
An incandescent nightlight bulb is either 4 watt or 7 watt. A 4 watt bulb uses 1/25th (0.04) the power of a 100 watt bulb. A 7 watt bulb uses 7/100th (0.07) the power of a 100 watt bulb. There are LED and other types of nightlights that use much less power than this. To find the energy total used multiply the power (in watts) by the total time the light is on (in hours) to get energy (in Wh). If you want kWh divide this by 1000 as a watt is 1/1000th of a kW.
How much energy does a 95 watt light bulb use in 40 seconds?
The energy is 95 x 40 watt-seconds (Joules).
How much energy does a 5 watt light bulb use off?
A lot

Which would use more energy a 50 watt bulb or a 75 watt bulb?
A 75 bulb will use more electricity.
What is the energy consumption of a 150 watt light bulb?
A 150 watt light bulb consumes 150 watts of energy per hour when it is turned on.
How much energy does a 120 watt light bulb use if it is left on for 36 gours?
120 watt * 36 hr = 4,320 watts

How hot does a 75 watt light bulb get?
When measured with an infrared thermometer it read 169.9 degrees F.
