What is Lighting ?
Lights are the equipment of a room, building, or street for producing light.Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Day lighting (using windows, skylights, or light shelves) is sometimes used as the main source of light during daytime in buildings. This can save energy in place of using artificial lighting, which represents a major component of energy consumption in buildings. Proper lighting can enhance task performance, improve the appearance of an area, or have positive psychological effects on occupants.

Basic types of artificial lights ?There are three basic types of lighting that work together
Ambient (general lighting)
Provides an area with overall illumination. Also known as general lighting, it radiates a comfortable level of brightness without glare
Task lighting
Helps you perform specific tasks, such as reading, grooming, preparing and cooking food,
Accent lighting
Adds drama to a room by creating visual interest. As part of an interior design scheme, it is used to draw the eye to houseplants, paintings, sculptures and other prized possessionshttps://www.americanlightingassoc.com/Lighting-Fundamentals/3-Types-of-Lighting.aspx

What is Ceiling ?
A ceiling is an overhead interior surface that covers the upper limit of a room. It is not generally considered a structural element, but a finished surface concealing the underside of the floor or roof structure above.

Concealed ceiling
Mostly Gypsum board used in this type of ceiling which is available in 4’ X 8’, 2’ X 2’, 2’ X 4’ sizes, MDF is also used but its not water resistant

In this type two sizes of panels are mostly used 24 X 24 and 24 X 48 which can be in different materials like Gypsum thermopore ect.
