Depends on how the light bulb is used.
Heat.
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.
Its has exposive heat
False. Low heat light bulbs can produce the same amount of light, and also save on energy.
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.
sometimes.It depends on the other bulbs
light bulbs are hot because the coils spread heat around the bulb.
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.
Most light bulbs waste energy as heat. Even LEDs. Large light bulbs require more power.
It might be the energy saving bulbs.
without light bulbs the modern world would be plunged into darkness. Light bulbs can not only produce light, but also heat, preventing the death of some pets, such as geckos, snakes, and lizards.
In typical light bulbs, or incandescent bulbs, the resistance to the current directed through the filament causes the filament to heat up, thus radiating light. The glass bulb around the filament is vacuum sealed to remove oxygen, which would rapidly oxidize and destroy the super heated, ultra thin filament. there are variations of this technology in which the bulb is not a vacuum, but is instead filled with different gasses surrounding the filament, which allows the filament to burn even hotter, creating more light. fluorescent bulbs work by creating a reaction between mercury vapor and phosphors. electric current excites the mercury atoms, which then release ultraviolet light. The ultraviolet light causes the phosphors to fluoresce, which creates light in our visible spectrum.
