Notes:
1. Φv is the total luminous flux output as
measured with an integrating sphere
after the device has stabilized.
2. The dominant wavelength is derived
from the CIE Chromaticity Diagram
and represents the perceived color
of the device.
3. θ_{0.90 V} is the included angle at which
90% of the total luminous flux is
captured. See Figure 5.
