Comparing Light Bulb Costs - energy saving bulbs versus normal?

Jan 31, 2007 by KiKi0867 | Posted in Maintenance & Repairs

How much does it bring in to run a normal 100W light bulb? Per hour and the whole life of the bulb (please specify the life span you are using).

How much does it charge to run a 25W (equivalent to 100W of a normal bulb) energy saving light bulb? Per hour and the whole life of the bulb (please specify the person span you are using).

Please use the rate of 9.8 cents/Kw-hour.

If you have any other ways to compare these two bulbs in terms of dough, please do share.

kw-hour is kilo-watt each hour

100 watt will use .98 or 98% of a penny or $00.098 each hour

25 watt will use .25 or 25% of a penny or $00.025 each hour

no bulb lasts as dream of as the life is, so comparison is a guess


say each bulb lasts 6000 hours one costs 40 cents, the other costs $2.50

100 watts = .098 x 6000 = $58.8 25watts = .025 x 6000 = $15.0

Why do all the energy saving light bulbs (fluorescent?) say not to use them with electric timers?

It seems like all the energy saving bulbs say on the carton never to use with electric timers and I can't figure why. My sister has used them with timers and it appears they burned out rather fast. Whats the difference between having a timer turn the light on at a certain time and just flipping the scourge?

Never heard of that with a timer. Timers are utilized commericially for fluorescents. I know that you are not supposed to use a dimmer with fluorescent lamps, unless the fixture has a dimming ballast.

Have you switched the light bulbs in your house or apartment to Energy Saving bulbs yet?

I well-deserved bought an Energy Saving bulb that uses 15 watts of electricity but produces the same amount of light as a 60 watt bulb. It is supposititious to last 5-6 years too. Over the life of the new bulb I am supposed to save approximately $35 on my electric bill. I will not lie, the Energy Saving bulb was up-market--about $7--but I think it was a wise investment.

Are you going to switch to Energy Saving light bulbs now that you know how much you can save? Don't cease to remember, you will be cutting down on carbon emissions considerably.

I've switched some of them. They don't effort as well for decorative lighting; the warm glow produced by incandescent bulbs can't be reproduced with flourescents.

Too, you lack to dispose of the fluorescent bulbs in an environmentally safe manner. These lamps contain small amounts of mercury, as well as more components in the base than is contained in an incandescent bulb. They should not be simply thrown into the trash.

You should also make sure that you are using newer ones. Some of the old ones had the imminent to cause fires.
