Light rays are one part of a spectrum of rays , all of the same basic type which are called electromagnetic radiation. The visible range from red to violet is just the section the human eye has evolved to be sensitive to. At lower frequencies there are AM radio waves, FM radio, UHF television, Microwaves, and Infra-red, and at higher frequencies ultra-violet, X rays, and gamma rays. All these waves are of the same type and all travel at the same speed, the so-called speed of light.
When you light a matchstick, you convert the chemical energy in the matchstick to heat energy. This matchstick when brought in contact with the candle converts the chemical energy in the candle to heat and light energy.Chemical energy turns to light and heat.
Light bulbs give out light and heat energy, while candles give out light and heat energy through a chemical reaction between the wax and a wick.
A heat lamp gives off radiant energy in the form of infrared light. This energy is absorbed by objects and surfaces, warming them up by increasing the kinetic energy of their molecules.
chemical potential energy (in the fuel being burned) to heat (thermal) energy and a little light energy.
A bonfire produces mainly thermal energy in the form of heat and light. The burning of the wood releases stored chemical energy in the form of heat and light energy.
Light energy and heat energy

Flashlights convert electric energy to light energy and heat energy.

Electrical energy--->sound energy+ heat energy and light energy Cheers M
Heat is electromagnetic radiation, and carries energy exactly as radio, light, X-rays, etc. do.
