Notes for Table 3:

1.

Test current is 1000 mA for all LXK2

Pxx4

xxxx Emitter products (L2K2

Mxx4

11

xxxx for LUXEON K2 with TFFC

Star 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.

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.

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 products are built with Indium Gallium Nitride (InGaN).

10. White power light sources represented here are IEC60825 class 2 for eye safety.

11. Luxeon K2 with TFFC is tested and binned at 25°C with a 20ms monopulse test to minimize heating of the junction

or case.
