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 ±5% tester tolerance.
4. Spectral width at �½ of the peak intensity.
5. Total angle at which 90% of total luminous flux is captured.
6.
�
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.
