Notes: (for Tables 2 & 3)
1. Dominant wavelength is derived from the CIE 1931 Chromaticity diagram and represents the perceived color.
Philips Lumileds maintains a tolerance of 0.5nm for dominant wavelength measurements.
2. Royal Blue product is binned by radiometric power and peak wavelength rather than photometric lumens and dominant
wavelength. Philips Lumileds maintains a tolerance of 2nm for peak wavelength measurements.
3. CCT 5ꢁ tester tolerance.
4. Spectral width at ½ of the peak intensity.
5. Total angle at which 90ꢁ of total luminous flux is captured.
6. θ½ is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
7. Cumulative flux percent within 45° from optical axis.
8. Off axis angle from lamp centerline where the luminous intensity reaches the peak value.
