It is not quite as straight forward as saying 95%. All energy going through the light bulb is being used in one form or another. If the room needs heat, the bulb is assisting in this heating. We use light bulbs like this for incubators or to keep pump rooms from freezing in the winter (two examples). In both of those cases, the light is really the only wasted portion of the energy consumed.
If we are discussing only the light portion of the bulb. 95% of the energy goes to non visible light consumption.
What else can I help you with?
What is the percent efficiency of a 60W light bulb that produces 6W of light energy?
The percent efficiency would be calculated by dividing the useful output by the total input energy and multiplying by 100. In this case, the useful output is 6W (light energy produced) and the total input is 60W (electricity consumed). Therefore, the efficiency would be (6/60) * 100 = 10%.
Why efficiency of solar photovoltaic cell is not 100 percent?
Because semiconductors such as silicon are indirect bandgap semiconductors, so some of the light energy is wasted as lattice vibrations (phonons).
What should happen as a filament in a light bulb gets hotter?
The basic idea is that eventually it gets hot enough to glow.Please note that this is not a very efficient way to produce light; a lot of the energy is wasted. Nowadays, better methods are available.
When an object loses kinetic energy due to a force of kinetic friction is the loss of kinetic energy transformed primarily into potential or thermal energy?
Kinetic friction is associated with thermal energy (and sound or light).
Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
What wasted energy is transferred from the bulb to its surroundings?
Wasted energy in the form of heat is transferred from the bulb to its surroundings. This is because light bulbs are not 100% efficient at converting electrical energy into light energy, so some energy is lost as heat during the process.
Is heat energy produced with the light energy in a torch?
Yes. The heat and light energy in a torch are separate. From the total energy input to the torch (chemical energy from batteries), Some is useful (the light energy) and some is wasted. (heat/thermal energy) The more efficient an appliance is ,the less energy out of the input energy is wasted. For example, an appliance may be 70% efficient. If it is supplied with 100J (joules) of energy, 70J will be useful and 30J will be wasted. Along with light energy, heat energy is also produced by a torch and is wasted. Heat energy is the most common form of wasted energy in appliances. Other appliances will waste energy in the form of heat, though it may not always be obvious.
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.
How long does energy efficient light bulbs STAY ON?
As long as they receive energy. The energy-efficiency refers to the fact that less energy is wasted as heat.As long as they receive energy.

What is the wasted energy from a bulb to its surrounding?
The wasted energy from a bulb to its surroundings is in the form of heat. Incandescent bulbs, for example, emit a significant amount of heat in addition to light, making them less energy-efficient compared to LED bulbs which produce less heat. This wasted heat energy contributes to higher energy costs and can also affect the surrounding temperature.
What are the benefits of the light bulb?
Although incandescent light bulbs remain a convenient source of light, as they have been for a long time, they are now an obsolete technology, because there are other sources of artificial light which are much more energy efficient. Fluorescent lighting is more energy efficient, and LEDs are even more energy efficient that fluorescent lighting.
What are two forms of energy when a light bulb converts 10 percent of electrical energy?
When a light bulb converts 10 percent of electrical energy, two forms of energy produced are light energy and heat energy. Since light bulbs are not 100% efficient, some of the electrical energy input is lost as heat energy.
When comparing two light bulbs the more efficient bulb will produce less what?
The more efficient bulb will produce less heat than the less efficient bulb. This is because a higher proportion of the energy input is converted into light output rather than wasted as heat.
What type of energy is wasted when energy is converted?
thermal, light and sound
What is solar energy about?
It is renewable It uses wasted heat and light energy
What happens to the energy wasted by the light bulb?
The wasted energy by a light bulb is primarily given off as heat. This heat is dispersed into the surrounding environment, contributing to the overall temperature of the room.
What is the percent efficiency of a 60W light bulb that produces 6W of light energy?
The percent efficiency would be calculated by dividing the useful output by the total input energy and multiplying by 100. In this case, the useful output is 6W (light energy produced) and the total input is 60W (electricity consumed). Therefore, the efficiency would be (6/60) * 100 = 10%.
