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.
An incandescent lamp is not cool to the touch unless it is an extremely low wattage. Heat given off by incandescent lamps is one of the drawbacks of the lamp. Total overall efficiency is reduced by the wasted heat.
The photosphere gives off heat and visible light.

A blacklight is a lamp used for decoration which gives off ultraviolet light.
90% of the energy used by a tungsten lamp is lost as heat because they depend on heating the filament until it gives off light. Only 10% is usable light.A 100 watt light bulb gives off 341 btu of heat.

Your standard light bulb where a filament is heated by a current passing through it. The heated filament then gives off light.
The part of an incandescent light bulb that gets hot and produces the light is called the filament.
All objects warm enough to glow. It depends on what you count as 'light'. If you count all electromagnetic radiation, then all objects above absolute zero give off their own heat and light. Except, maybe, black holes. The answer for them is not so clear-cut.
