Notes for Table 2:
1. Test current is 350 mA for all LXMLꢀPxx1ꢀ0xxx products.
2. Dominant wavelength is derived from the CIE 1931 Chromaticity diagram and represents the perceived color.
Philips Lumileds maintains a tolerance of 0.5 nm for dominant wavelength measurements.
3. RoyalꢀBlue product is binned by radiometric power and peak wavelength rather than photometric lumens.
Philips Lumileds maintains a tolerance of 2nm for peak wavelength measurements.
4. CCT 5% tester tolerance.
5. Typical CRI (Color Rendering Index) for CoolꢀWhite is 70, NeutralꢀWhite is 75 and WarmꢀWhite is 80.
6. Spectral width at ½ of the peak intensity.
7. Total angle at which 90% of total luminous flux is captured.
8. Viewing angle is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
9. All white, green, cyan, blue and royalꢀblue products are built with Indium Gallium Nitride (InGaN).
10. All red, redꢀorange, and amber are built with Aluminum Indium Gallium Phosphide (AlInGaP).
11. CoolꢀWhite, NeutralꢀWhite, WarmꢀWhite, Blue and RoyalꢀBlue power light sources represented here are IEC825
class 2 for eye safety.
