Measures:
Total spectral flux (watts)
Luminous flux (lumens)
Chromaticity (x,y and u,v)
Correlated Color Temperature (CCT) Kelvin
Color Rendering Index (CRI)
Peak wavelength
Dominant wavelength
Luminous efficacy (lumens per watt)

Pass/Fail green/red display
Base up or base down internal testing
2 pi external testing for directional lamps

All LFC systems include:
Integrating sphere: 0.5, 1.0, 1.5, or 2.0 meters diameter
  coated with Labsphere Spectraflect^® 98% reflectance material
Port for 2 pi external measurements
Post and wiring for 4 pi internal measurements
    -post can be mounted from bottom or top of sphere
NIST-traceable, NVLAP 17025 accredited spectral flux calibration lamp
  from Labsphere (required for ENERGY STAR compliant testing)
Socket assembly for calibration lamp
Auxiliary lamp for test lamp self-absorption correction
  For highest accuracy, the system applies absorption correction
  as a function of wavelength.
  Complies with LM-79 guidelines for photometric and electrical
  testing.
Port and baffle for auxiliary lamp
CCD array spectrometer and input fiber optic cable
Port and baffle for spectrometer detector
DC power supply 30V, 5A for powering calibration and
  auxiliary correction lamps
Electrical rack (with single cable connection to sphere)
Mtrx Light measurement and system control software
System manual

AC/DC systems also include:
Arroyo relay controller for automatically switching between
calibration lamp and auxiliary lamp
And either:
  Parwa AC power supply 0-300V, 1kW
  and TET power meter
or
  Chroma AC power supply 0-300V, 1.5kW
  and Yokogawa power meter
