High End Trim

The capability to set the maximum light output to a less-than-maximum state of an individual or group of luminaires/lamps at the time of installation or commissioning. High-end trim must be field reconfigurable. This capability is distinct from automatic compensation for lumen depreciation, which automatically increases output as a system operates over time. *While the DLC specifically requires “High-end trim”, some manufacturers refer to this capability as “task tuning” or “tuning” within their system interfaces. Refer to NEMA LSD 64-2014 for definitions of lighting controls terminology.
