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.

Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
Does a low-energy light-bulb create more heat in a room?
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
Does energy saving bulb have fillament?
No
When the light bulb is lit electrical energy is changed into light energy and?
When lighting a light bulb, it is changed into light and heat/thermal energy.
What energy saving products should every household contain?
Every household should contain one of the most energy saving products which is the light bulb as everyone uses electricity and it will cut down the costs of buying new light bulbs every week.
Can energy saving light bulb charge a phone?
No. An energy saving light bulb is just a light bulb, and can't charge anything. The reason it's called an "energy saving" device is that it can give you the same amount of light while using less electrical energy than older bulbs used.
What does an energy saving light bulb do?
It uses less energy to produce the same amount of illumination as a standard light bulb
What type of light is 20w energy saving bulb Halogen Indandecent neon fluorescent etc please help?
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
How many killawatts are in a standard light bulb?
"A standard light bulb I would consider to be a 60 watt light bulb, and kilowatts are the amount of usage in a light bulb. From my research I have found that a standard 60 watt light bulb uses approximately 1.44 Kilowatts per hour."
Are there gases and chemicals in a light bulb?
yes there is in the spiral energy saving light bulbs there is mercury
How many kilowatts does a light bulb use?
Thsi depends on the light bulb specification. For example if you buy a standard 60W light bulb from your supmarket then this will consume 0.06kilowatts. Its simple just divide the wattage stated on the light bulb by 1000 to give you the kilowatts
What is the difference between the energy saving light bulb and the filament bulb?
Energy saving bulbs (typically LEDs) provide higher lumens per watt compared to filament lamps.
Why does a non energy saving light bulb give off more heat than an energy saving light bulb?
Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.Any of the wasted energy that is not converted to light will be converted to heat.
Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
What unit is k for light bulbs?
k or kw stands for kilowatts - the amount of kilowatts the bulb burns to light up the filament.
What percentage of energy does an energy saving bulb save compared to an ordinary bulb?
It varies, depending on the specific model, but an energy-saving (fluorescent) light bulb should save at least half the energy, for the same luminosity, compared to the old-fashioned incandescent light bulbs. The incandescent light bulbs ought to be outlawed, except for specific purposes where the heat they generate is actually needed.
Does a low-energy light-bulb create more heat in a room?
Compared to other types of light-bulb, energy-saving light bulbs will create less heat. This is because any wasted energy is converted to heat.
