Dial the Output Down When Possible with Trimming
Dear Reader:
LED fixtures are tested vigorously before being released to the market (see Cameron Miller’s PowerPoint from the National Institute of Standards & Technology), with the object being to measure not only initial lumen output, but to project what that output will be over the course of its useful life. The end of life for a fixture is viewed as that point at which the fixture has depreciated over time to 70% of its initial output.
Think about this .. if a fixture is “useful” up to 70% of its initial output, then the initial output includes a premium of 30%, representing icing on the cake (a surplus of lumens) over and above what is actually needed, given the work required by the fixture over that period of time.
An energy-conscious Facilities Manager will ensure his/her lighting design speaks to this premium, and anticipates the physical depreciation of the fixture over time.
