What is an ideal office?

Ergonomics (or human factors) is the scientific discipline concerned with the understanding of interactions among humans and other elements of a system, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance. This is according to.

The amount of energy a light emits per second, measured in lumens (lm).

It is a unit of luminous intensity of a light source in a definitive direction.

The amount of luminous flux per unit area.

A name given for a unit of luminance

You can think of it as the total amount of light emitted from a light bulb.

The amount of flux emitted through a known solid angle.

The measurement of radiant flux on a known surface area.

The measurement of total perceived power emitted in all directions by a light source.

The amount of light emitted by a source in a particular direction.

Refers to the amount of light incident on a surface.

Instrument that measures light intensity.

Determine the visible energy output of a light source

Measure the visible energy falling on an object's surface.

Uniquely associated with noise measurements, it is a term borrowed from electrical-communication engineering, and it represents a relative quantity.
