What are the Limitations of Using Par Value to Evaluate LED Lights?
While par value is a useful metric for evaluating LED lights, it has several limitations. One of the main limitations is that it does not take into account the color rendering index (CRI) of the LED, which is a measure of its ability to accurately render colors. Additionally, par value does not account for the LED’s beam angle, which can affect its overall brightness and illuminance. Furthermore, par value is not a direct measure of the LED’s lifespan or reliability, which are critical factors to consider when selecting LED lighting. As a result, par value should be considered in conjunction with other metrics, such as CRI, beam angle, and lifespan, to get a comprehensive understanding of an LED’s performance and suitability for a particular application.
The limitations of using par value to evaluate LED lights highlight the importance of considering multiple factors when selecting LED lighting. For instance, an LED with a high par value may not necessarily have a high CRI or a long lifespan.
