Main one is light energy. Also some heat is produced
A typical lamp would convert electrical energy into light energy. And lots of heat too.
A torch typically uses chemical energy stored in a battery or fuel cell to produce electrical energy for the light source, which then converts it to light energy.
A light bulb uses electrical energy, and produces light, as well as heat.
A lamp typically requires electrical energy to function. This energy powers the light bulb, allowing it to produce light when the electrical circuit is completed.

The sun produce light and nuclear energy
light and thermal energy
Fluorescent lights use far less energy than any of the others listed.

Calories don't "produce" energy; calories are a UNIT OF ENERGY.
The sun produces a (nearly) continuous spectrum (gaseous elements in the Sun's atmosphere absorb certain frequencies, making it not quite truly continuous) because it's emitting light due mainly to its temperature. This kind of radiation is called "black body" or "cavity" radiation, and it's a continuous spectrum. Fluorescent lights produce light by a phenomenon known as (hold on for the shocking revelation) fluorescence. This kind of radiation is related to transitions between specific electron energy levels, and therefore consists of discrete lines. In old or cheap fluorescent tubes, there might be only a couple of lines. Most modern ones use a mixture of phosphors that emit light at different frequencies, so you might see half a dozen or more lines in the spectrum.
