Notes for Table 3:

1.

Test current is 350 mA for all LXK2

xxx2

xxx (L2K2

xxx2

11

xxxx for K2 Star) products, and 1000 mA for all

LXK2

xxx4

xxx products (L2K2

xxx4

11

xxxx for K2 Star).

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.

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.

4.

CCT ±5% tester tolerance

5.

Typical CRI (Color Rendering Index) for CoolWhite product is 70, NeutralWhite is 75, and WarmWhite 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 royal blue products are built with Indium Gallium Nitride (InGaN).

10. All red, redorange and amber products are built with Aluminum Indium Gallium Phosphide (AlInGaP).

11. Blue and royal blue power light sources represented here are IEC825 class 2 for eye safety.
