I use a 75 watt heat lamp in 36" habitat. at the end i use it on, it is about 80-82 degrees. it depends on how far away the bulb is and how the temp. is naturally. so don't place it close enough to get touched or burned by whatever your warming not burning. Hope this helps a bit. not a professional. Just experienced this much.

Heat source.
Light and heat energy.
heat
depending on the bulb. alot of heat
a lamp in an elctrical circuit provides light and partly heat. a lamp in an elctrical circuit provides light and partly heat.
electricity, solid fuel, fire(using wood), infrared light, light bulb or heat lamp, gas e.t.c
Electrical energy absorbed by the lamp's filament produces thermal energy as well as light.
The light bulb is inside the lamp base, right?so, when you turn on the lamp, the light shines THROUGH the lamp base, although dimmer, so you can se both. if you took the lamp base off, the light bulb would look brighter.
No, an incandescent bulb i.e. a bulb that emits light by the generation of heat, emits white light and is therefore not monochromatic. For a source to be monochromatic, the light emitted must be of a single wavelength.
In a lamp?
Depends on the lamp and bulb if you are referring to temperature. Directly related to energy wasted as heat and not converted to lumens. The element or filament has a higher resistance and displaces heat. Inefficient unless heat is your goal as with a heat lamp. If you are referring to degrees of diffusion; that depends on the bulb or the shades diameter, the shades reflectivity and distance of the light source to the end of the shade.
