Note: 1. Luminous intensity is measured with a light sensor and fil
ter combination that approxi
mates the CI
E
(Comm
ission International De L'Eclairage) eye-response curve.
2.
θ
1/2
is t
he off-axis angle at which the luminous int
ensity is half the axi
al luminous intensity.
3. The dominant wavelength,
λ
d
is derived from the CI
E chromaticity diagram
and represents the si
ngle
wavelength which defines the color of the device.
4. The Iv g
uarantee should be added
±
15% .
