Note:

1. ØV is the total luminous flux output as measured with an integrating sphere.

2.

1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

3. The dominant wavelength,

d is derived from the CIE chromaticity diagram and represents the single

wavelength which defines the color of the device.
