  • Require that L70 data was produced per testing that meets the LM-80-08 standard.

     

  • Require the LM-79-08 report from an independent test lab, with the LED array tested inside the fixture.

     

  • Carefully consider the fixture manufacturer’s approach to thermal management.

     

  • Specify or verify the (LLF) Light Loss Factor used on any photometric comparisons/layouts.

     

  • Confirm the (CCT) Color Corrected Temperature that any data is based on.

     

  • Compare or specify the Luminaire Efficacy of any fixture(s) under consideration, in terms of the Downward Delivered Lumens.

     

  • Verify the drive current(s) used to produce published data re lumen depreciation and efficacy. If it varies, are there also variable heat sinks that correspond?

     

  • How many years is the LED array warranted? What triggers it? What does the warranty entail? Most importantly, who is backing up that warranty?

     

  • Confirm the same warranty issues for the driver.

     

  • Carefully consider the fixture manufacturer’s approach to lumen delivery & optic systems.

     

  • Periodically check the CALiPER website for updates.
