fluorescent lights
Exothermic Reaction
infeared
Electrical? Anything that produces light, heat, or motion when powered
Heat, which then produces light.
Exothermic reactions. E.g. combustion, oxidation
Yes it does The lighted back plane area produces the most amount of heat. The least amount of heat is produced by led type displays. The light transmitted from the television display produces a very small amount of heat.
The chromosphere produces the light and heat for the sun.

steel wool burns in oxegen and produces heat and light
synthesis
A light bulb (technically, a lamp) converts electrical energy into a mixture of heat and light ... the makeup of that mixture depends upon the type of lamp being used. An incandescent lamp produces most of its energy in the form of heat and relatively little light ... a fluorescent lamp produces a higher percentage of light and less heat ... gas/vapor glow lamps (including lasers) produce an even higher percentage of light ... and light-emitting diodes (LED) produce the highest percentage of light presently available.
The chemical energy of the fuel is converted into light and heat energy.
Exothermic Reaction
Nearly anything that produces light will also produce heat.
combustion
When any fuel combusts it produces heat, light and a little sound. The majority of the energy produced will be heat.
