Three things that produce heat are a light bulb, fire, and the sun

Stimulus?
No, not all objects and things produce shadows. Shadows are created when an object blocks light from a source, so objects that are transparent or allow light to pass through without obstruction may not produce a distinct shadow.
Some things that produce both light and heat include incandescent light bulbs, candles, and fireplaces. These sources generate both light and heat through the process of combustion or electrical resistance.
Lumen is a simple way to indicate the amount of light the projector has to produce the brightness of the picture. The higher the number the brighter the picture.
A firefly is an example of an object that produces its own light. The sun is another.
No. Looking at a picture of an eclipse will not hurt your eyes. Since it is only a pictures and doesn't produce any blinding light, it will not cause any damage.
You can see things that do not produce their own light because they reflect light from other sources. When light from a source like the sun or a lamp hits an object, it bounces off the object and into your eyes, allowing you to see it. This is how you can see objects like books, furniture, and buildings that do not emit their own light.
