The dominant wavelength, Aq, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 2. The radiant intensity, I,, in watts per steradian, may be found from the equation I, = Iy/ny, where ly is the luminous intensity in candelas and ny is luminous efficacy in lumens/watt. 3. T- 15/4. 4.
