To calculate an answer, a time interval must be given. The utility company bills the customer in kW/h of use. Use a time interval and multiply it by the 5 watts. Divide the answer by 1000 to give you kilowatts. Multiply that answer by the cost of electricity in your area. This can be found on your utility bill or you can phone the utility company to see what you are charged. It will be stated as so may cents per kilowatt hours. I pay .089 cents per kilowatt hour as an example.
no , it will burn out
lumenicity (how much light something gives off) is not directly related to power. A 60 watt LED will give off more light than a 60 watt incandescent. You should check the manufacturers information. Light.com (first one to show up in my google search) specifies a 500 lumen 8 watt LED. the 52W incandescent "soft white" bulbs I have on many dimmers in my home put of 710 lumens as a comparison.
very much :-)

it costs about €500

It would use less electrical energy to burn the 60 watt light bulb for 900 seconds. This is because the total energy consumed is calculated by multiplying the power (in watts) by the time (in seconds), so for the 60 watt bulb: 60 watts * 900 seconds = 54,000 watt-seconds, and for the 100 watt bulb: 100 watts * 500 seconds = 50,000 watt-seconds.

The cost to run a 1000 watt light bulb for 24 hours is dependent on your electricity rate. Assuming an average rate of $0.12 per kilowatt-hour, it would cost $12 to run the light for 24 hours (1000 watts = 1 kilowatt).
W*cost*khw/1000
A halogen bulb IS ITSELF a type of incandescent illumination source. A 40 Watt traditional incandescent bulb usually emits about 400 to 500 lumens while a halogen may emit close to twice that. So a 25 W halogen might give out as much light as ah older style 40 W bulb.
Yes, that's the question. A 1000 Watt light uses... 1000 Watts. A 500 Watt light uses, you guessed it... 500 watts. It depends on the size of the bulb. ACTUALLY... Watts are a measure of power, Joules are the measure of energy - you can simply convert watts/hour or watts/second to joules but to say that a 1000 Watt light bulb uses 1000 watts is a ridiculous thing to say =D watts are Wh-1 or Ws-1
A 300 watt light bulb can reach temperatures around 350-500 degrees Fahrenheit when operating. This heat is generated as a byproduct of converting electrical energy into light and can pose a fire hazard if the bulb comes into contact with flammable materials. It is important to follow safety guidelines and avoid touching the bulb when it is in use.
That will vary on the manufacture and quality of the bulb. There is no set amount of lumens for a 40 watt halogen or any kind of bulb for that matter. To find out the lumen output you need to look at the box it came in as it should be stated. If you don't have the box it may be tricky to find out. You will have to see if you can find the manufacture somewhere on the bulb then google it and check the specs. It's probably safe to say its going to be around 500 lumens on average.
The amount of light (Lumens) delivered by a light bulb cannot be determined by it's wattage. Bulbs of any wattage by different manufacturers can have different output (lumens). Everything else being the same, a 34 watt 110volt bulb will put out about half the light than a 34 watt 220 volt bulb, and a 12 volt one will put out about 10% of the light as the 120 volt one will.
it will cost 500$
