About 80%. An incandescent bulb produces 12 lumens per watt, (15 for halogen) while a CFL produces about 60 lumens per watt.

Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
What causes the bulb to light in a closed circuit?
Energy flowing through the filament. In a traditional incandescent bulb most of the energy is radiated as heat which is why they are viewed as inefficient.
Why is an incadescent bulb a very inefficient light source?
An incandescent light bulb is very inefficient light source because of the amount of heat energy wasted when it is energized.
What is the name for a regular light bulb?
incandescent
Does a 25 watt light bulb draw more current than a 60 watt light bulb?
No, a higher wattage INCANDESCENT light bulb uses more current than a lower wattage INCANDESCENT light bulb. Some CF and LED bulbs are rated by the amount of light that an incandescent bulb would produce, but they are also rated by the wattage that they use.
Does an incandescent bulb and a light stick use the same form of energy to create light?
No. The incandescent bulb uses electrical energy and the light stick uses chemical energy.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
What is the least efficient kind of light bulb?
It is the Incandescent light bulb. Most of the energy are lost as heat
What device converts electrical energy into heat and light energy?
An incandescent light bulb would be a prime example.
What energy trasnformations occur in a incandescent light bulb?
In an incandescent light bulb, electrical energy is transformed into thermal energy and then into light energy. When electricity flows through the filament of the bulb, it heats up and becomes white-hot, producing thermal energy. This thermal energy then causes the filament to glow and emit light energy.
Why does an incandescent bulb of similar energy 60 watts versus 15 watts make water evaporate more quickly than a compact fluorescent lightbulb?
An incandescent bulb gives off more heat than a fluorescent bulb.
Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?

Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
What is the job of a light bulb?
The job of a light bulb is to convert electrical energy into visible light energy. (Not ALL of the electrical energy a bulb uses is converted to light energy. Their efficiency is quite low. An incandescent light bulb is more efficient as a heater than as a source of visible light. Fortunately, our eyes are very sensitive.)
Why do you think a light bulb feels warm?
A light bulb is designed to take electrical energy and radiate it as electromagnetic energy.It would be nice of all of that energy came out in the form of light, but that has never been accomplished yet. An incandescent light bulb ... the original kind ... radiates much more heatenergy than light energy. In other words, an incandescent light bulb works much more efficientlyas a heater than it does as a source of light.
What is incandescent light bulb?
An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light which produces light with a wire filament heated to a high temperature by an electric current passing through it, until it glows.
What kind of energy does a toaster converts electrical energy?
Mostly heat, and a little bit of light. A lot like an incandescent light bulb.
