Efficiency of Lamp Measurement
Efficiency of a lamp is measured in Lumen per Watt (lm/W).
Explanation
- Lumen (lm): Lumen is a unit of measurement for the total amount of visible light emitted by a source. It indicates the brightness of the light.
- Watt (W): Watt is a unit of power that measures the amount of energy consumed by the lamp.
- Lumen per Watt (lm/W): This measurement quantifies how effectively a lamp converts electrical power into visible light. A higher lumen per watt value indicates a more efficient lamp.
Therefore, when evaluating the efficiency of a lamp, the Lumen per Watt (lm/W) measurement is used to determine how much light output is produced per unit of electrical power consumed. This metric helps in selecting energy-efficient lighting solutions for various applications.
