Note:

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

2. θ1/2 is the off-axis angle at which the luminous intensity is half the axial luminous intensity.

3. The dominant wavelength, λd is derived from the CIE chromaticity diagram and represents the single

wavelength which defines the color of the device.
