LED luminaire performance: changing traditions can set the right expectations
LED technologies can show radically different photometric performance and life when used in different application environments. Photometric data produced according to traditional testing standards are not very useful for LED luminaires, according to Nadarajah Narendran, Jean Paul Freyssinier, and Jennifer Taylor.
However, as with many traditional luminaires, not all LED-based luminaires provide reliable performance. While the LED itself may have good quality and performance as a bare device, its integration into a luminaire and that luminaire’s installation environment are key to the final product performance and whether it will stand up to customer expectations. Luminaires that do not meet customer expectations can turn off users from promising LED technology.
