What are Lumen and Watt

Lumen, a unit of luminous flux, measures the perceived power of light. It quantifies the amount of light emitted by a source or received by a surface. Unlike watts, which denote energy consumed, lumens focus on the brightness perceived by the human eye. This distinction is crucial in lighting design, where the goal is to achieve desired illumination levels rather than merely increasing energy usage. For instance, LED bulbs are often marketed by lumens, highlighting their efficiency in producing more light per watt compared to traditional bulbs. Understanding lumens helps consumers make informed lighting choices.

Watt is a unit of power in the International System of Units (SI), named after the Scottish engineer James Watt. It quantifies the rate of energy transfer or conversion. In everyday terms, watts measure electrical power consumption, such as the amount used by household appliances. For example, a 60-watt light bulb consumes 60 joules of energy per second. Understanding watts is essential for energy management, as it directly relates to energy efficiency and consumption costs. In lighting, watts indicate the power input, though modern energy-saving technologies focus on lumens for brightness instead.
