The relative brightness of a lamp refers to its brightness in comparison to other lamps. It is a measure of how bright a lamp appears in relation to other light sources. The full brightness of a lamp, on the other hand, refers to its maximum brightness output. This is the highest level of illumination that the lamp can produce. Both relative brightness and full brightness are important factors to consider when choosing a lamp for a specific lighting application. **

Shadows can appear different in brightness due to several factors such as the angle of the light source, the distance between the object and the surface it is cast upon, and the reflective properties of the surface. A shadow will be darker when the light source is closer to the object, creating a more defined shadow with sharper edges. Additionally, shadows can also appear lighter or darker depending on the surface they are cast upon, with more reflective surfaces producing lighter shadows. **

The brightness may suddenly lower due to a variety of reasons such as a decrease in power supply, a change in display settings, a malfunction in the device's hardware, or the activation of a power-saving mode.

Checking the device's settings, power source, and ambient light levels can help identify the cause of the sudden decrease in brightness. **
