Why can light bulbs be called heat bulbs?
Heat bulbs would be a more appropriate name because incandescent bulbs transform 90% of electricity received into heat and 10% into light. New Compact Fluorescent light bulbs use only 20% to 30% of the energy needed to power a standard bulb for the same wattage.
Is the halogen bulb a hotter heat then other light bulbs?
sometimes.It depends on the other bulbs
What is difference between R40 and BR40 light bulbs?
R40 is a Red Heat Lamp Light Bulb BR40 is a Clear Heat Lamp Light Bulb
What causes heat pollution?
heat pollution is caused by lots of things for example light bulbs !! They produce more heat pollution than light, also cars, factories, farms, etc.
Why do ordinary light bulbs take more electrical energy than efficient bulbs?
The filament on normal light bulbs require a higher current of electricity to light up, and are more resistant to electricity as well. This causes it to use more electricity and generate more heat.
Why do light bulbs glow?
Either the filament or a gas inside is heated. Once it gets hot enough, it dissipates some of the energy as heat and light.
What is it that normal light bulbs give off much more than fluorescent light bulbs?
Heat.

What do gases in a light bulb do?
heat up and glow
What are advantages of the incandescant light bulbs?
Its has exposive heat
Low heat light bulbs produce less light but save on energy costs true or false?
False. Low heat light bulbs can produce the same amount of light, and also save on energy.
Are light bulbs better at creating heat or light?
Depends on how the light bulb is used.
Is the halogen bulb a hotter heat then other light bulbs?
sometimes.It depends on the other bulbs
Why are light bulbs so hot when they are turned off?
light bulbs are hot because the coils spread heat around the bulb.
What is the difference between fluorescent bulbs and regular light bulbs?
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.
Why is the power of a light bulb large?
Most light bulbs waste energy as heat. Even LEDs. Large light bulbs require more power.
Are glow sticks exothermic or endothermic glow sticks?
Glow sticks are exothermic.Exothermic is when heat/energy is released. And that is exactly what glow sticks do. but the energy being released is in the form of light.
