A power saving light is also known as a Compact Fluorescent Lamp (CFL).A typical CFL is rated at about nine (9) to thirteen (13) Watts, and the energy consumed by each is 0.009 kW and 0.013 kW respectively.

How much energy does it take to light phosphorescent light?
It depends upon power of phosphorescent light. The power determines energy consumption.
Why switch to energy saving bulbs?
Energy saving light bulbs have a couple perks about them. One, is there is a much cleaner manufacturing process with less waste. Two, they can help conserve electricity resulting in lower power bills every month - and less power needed to be generated. Three, they last longer so that fewer are thrown away into landfills.
What are the benefits of using an energy saving light bulb?
Save energy!This means lower electrical costs. Typically "energy saving" cost more in initial costs and depending on the frequency of use may or may not pay for themselves over the life of the device.However, items like energy saving florescent light bulbs have become much smaller in physical size, quite inexpensive AND now deliver more light, making them a very attractive item.
Are energy saving light bulbs cheaper?
In general an energy saving bulb will be much more expensive to buy than an incandescent bulb, but much cheaper to operate as it uses only a fraction of the electricity. Ideally the money saved in use more than offsets the purchase price making an energy saving bulb cheaper over its entire lifetime, but in reality this may not be the case.
How much energy does a 5 watt light bulb produce?
None. But it does convert 5 watts of electrical power (energy per unit time) into 5 watts of [light + thermal] power.
How much energy do you save with 10 light bulbs off?
That depends on the power used by each light bulb. Look at the specifications for a specific light bulb, then multiply the power by 10. Note that energy = power x time; that is to say, the energy spent by a light bulb depends on its power, but also on how long you keep it on. Specifically, watts = joules x seconds.
Which light bulb is best for cost saving?
Florescent light bulbs produce a similar amount of light with much less power than incandescent light bulbs. Their initial cost is paid back in energy savings. They also last a lot longer. I exchanged every light in my house for florescent bulbs years ago and I haven't changed more than 4 or 5 in all that time. LED bulbs are now on the market and are very expensive. But they use even less power to produce similar light and last many times longer than florescent bulbs. They are quite expensive, but what you get is an almost permanent bulb. In the future we will tell our grandchildren how we used to change light bulbs and they won't understand. I see a day when the bulbs become permanent parts of light fixtures and will not be replaceable in any typical sense.
How much energy will a 100w light bulb convert to light and heat if it is left burning for 1hour?
Power = Energy/time 100W=Energy/360 Seconds Energy = 100/360 Energy ≈ 0.27 Joules
How much energy does an LED light consume?
An LED flood light uses a fraction of the power of a traditional flood light. It uses less then 1/4 the the power. They also last much longer the traditional flood lights.
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 does fluorescent light bulbs help conserve energy?
It's because it need only 20% of the electrical power to produce as much light, therefore less energy is wasted.
How many kilowatts does a energy saving light bulb use?
Energy-saving bulbs use much less than 1 kilowatt and most of them use less than 40 watts which is 0.04 kilowatts. A 20 watt bulb uses 1 kilowatt-hour of energy if run for 50 hours.
