What are Watt and Lumen

A watt is a unit of power named after James Watt, the Scottish inventor. It is defined as the rate at which work is done or energy is transferred in an electric circuit. One watt equates to the transfer of one joule of energy per second. This unit is pivotal in understanding and calculating electrical, mechanical, and thermal power. Widely used in various fields, it helps in determining the energy consumption of devices, thus playing a crucial role in energy management and conservation strategies.

A lumen is a unit of luminous flux in the International System of Units (SI). It measures the total amount of visible light emitted by a source. Unlike watts, which measure power, lumens quantify the perceived brightness to the human eye. This distinction is crucial in lighting as it helps consumers understand how much light a bulb emits for the power it consumes. The more lumens, the brighter the light. Thus, lumens serve as a standard for comparing and choosing lighting products for efficiency and efficacy.
