The light bulb gives light be heating the filament. Roughly speaking, it is emitting black body radiation. Plank's Law gives you the formula.

We have NO TROUBLE at all seeing visible light wavelengths from the sun.We cannot see the radio, microwave, infrared, ultraviolet, or x-ray "light" from the sun because our eyes are not sensitive to these wavelengths.
That would be black.
Color refers to the perceived hue of an object or light source, determined by the wavelengths of light it reflects or emits. Brightness, on the other hand, refers to the intensity of light emitted or reflected by an object, regardless of its color. Color can be affected by factors like pigmentation, while brightness is influenced by the amount of light hitting a surface.
Light refers to the presence of illumination or brightness, while dark refers to the absence of light or brightness. Light is visible, allows us to see things clearly, and can represent positivity and clarity, whereas dark is often associated with shadows, obscurity, and negativity.
Relative brightness refers to how bright an object appears compared to another object. It is often used in the context of visual perception to describe the perceived brightness of different objects in a scene. Brightness can be influenced by factors such as the intensity of light emitted or reflected by an object and the sensitivity of the human eye to different wavelengths of light.
The median of light refers to the midpoint of a distribution of light intensity or brightness in a given context. In terms of physics, it can also relate to the median wavelength in a spectrum of light, which represents the wavelength at which half the total light is of shorter wavelengths and half is of longer wavelengths. In photography or imaging, it might refer to the median value of pixel brightness in an image, useful for analyzing exposure levels.
The color produced when objects reflect light depends on the wavelengths of light that are reflected. For example, an object that reflects all visible wavelengths of light appears white, while an object that absorbs all wavelengths appears black. Other colors are produced based on the specific wavelengths that are reflected.

White light is a combination of all the colors in the visible spectrum. It is produced when light from a source, such as the sun or a light bulb, contains a mix of different wavelengths of light. When these wavelengths combine, they create the perception of white light to our eyes.

Color is the visual perception of different wavelengths of light. It is typically described by its hue, saturation, and brightness.
The brightness of light produced by a source can be measured using a device called a photometer or lux meter. These tools measure the illuminance of light in lux, which is a unit of measurement for the amount of light that reaches a surface. By placing the photometer at the location where the light is being emitted, you can quantify the brightness level.

The brightness of the color of an object is determined by the amount of light that is reflected by the object's surface. The color itself is determined by the wavelengths of light that are reflected, with the object appearing brighter or darker depending on how much light is reflected back to our eyes.
