Why does LED lighting seem brighter or “clearer” than fluorescent or incandescent lighting?
The light cast from LEDs covers a wider spectrum than fluorescent or incandescent lighting. And while there are many devices used to compare the amount of light output by different sources, the measure that truly matters most is the human eye. Lights are rated by their total output in Photopic lumens – the total amount of light cast by a fixture. In conventional lighting, this measurement can include a significant quantity of low quality yellow or orange light. The human eye sees light in Scotopic lumens. This explains why people are often surprised to find LED lights look brighter, even though an LED fixture is rated at a lower number of lumens. For the human eye, quality can matter much more than quantity. ………………………………………………………………………………………………………………. Facts at-a-glance Download ……………………………………………………………………………………………………………….
