The upper light is the light that falls from the ceiling. It is commonly used in households as well as in industry. Households are smaller sources of light that improve visibility, for example, in the bathroom or in the pantry. In industrial buildings they are in the form of strong luminaires that produce a lot of light. Lamps in factories and warehouses can take many forms. Halogen lights are commonly used, but in recent years, these energy-saving lights are being enforced with LED technology.
