What does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
How much energy does a 5 watt light bulb?
That varies a lot, depending on the type of light bulb. The old-fashioned incandescent light bulbs produce much less light, for the same power, than the fluorescent light bulbs.That varies a lot, depending on the type of light bulb.

How much energy does a normal light-bulb make in comparison to a colored one?
They are the same light bulb, so they are the same. The colored bulb has coloring applies on its outside surface. They do not make energy, they use energy.
How much energy do you save per hour if you replace a 60 W light bulb with a 55 W light bulb?
18,000 J
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 does the filament of a light bulb allows the light bulb to change electrical energy to?
The filament of a light bulb overs enough resistance to current flow, that the filament heats up so much that it will glow and produce visible light.
What color should a room be painted to save energy?
Try light color that let in light so that your bulb wont have to produce as much energy to light up a room.
Why Led bulb are better than filament bulbs for maximum reduction in the consumption of electrical energy explain?
LEDs produce visible light and not heat. Filament bulbs use much of their energy to produce heat. The LED bulb produces more light per watt consumed.
Different color light bulb affect how much energy it has?
No, Colored light bulbs holds the same amount of energy a regular light bulb holds.
How much of the electrical energy used to light an incandescent bulb is converted into light energy?
About 2 %.
How much energy to produce one light?
Lights vary tremendously in power, but the normal incandescent bulb takes 100 watts. Low energy bulbs can give the same light at 20 watts
What energy is wasted from a lamp?
that is dependant on the wattage of the bulb, the wattage 40W, 60W, 100W, is the rated power that a bulb will use. 1kW is equal to 1000W 1kWh is equal to 1000W per hour. kW stands for kilo watt I hope that helps

Does the life of a light bulb depend on its wattage?
Yes, Of Course The lifetime depends on the wattage. The wattage is the amount of Power the light bulb uses, and the life time depends on the power. Thank you
In a 60 watt light bulb how much energy is converted into heat?
What are the uses of Heat energy
