What exactly do color temperature, lumens, candelas, and color rendering mean?
What is luminous intensity? It is the unit of luminous intensity, used to measure the luminous ability of a light source in a specific direction. For example, the luminous intensity of car high beams is usually more than tens of thousands of candelas, which can illuminate the road ahead at a long distance, while the luminous intensity of ordinary flashlights may only be a few hundred candelas. Applications: In road lighting design, it is necessary to reasonably set the luminous intensity of street lamps according to factors such as road grade and traffic flow to ensure that the road has sufficient brightness and uniformity. In stage lighting design, lamps with different luminous intensities are also used to create various lighting effects according to the needs of the performance.What is illuminance? Illuminance (lux, lx) refers to the brightness when light hits an object. It represents the luminous flux per unit area and affects the perception of an object’s brightness. The farther the light source is from the object, the faster the illuminance decreases. A flashlight appears dimmer from a distance than up close precisely because the illuminance becomes lower. What is color rendering index? Color rendering refers to the ability of
