  • Luminous Intensity Measurement allowance is ± 10%.
  • θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.
  • The dominant wavelength (λd) is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device.
