The dominant wavelength, λd, is derived from the CIE chromaticity diagram and represents the single wavelength which defines the color of the device. 2. The radiant intensity, Ie, in watts per steradian, may be found from the equation Ie = IV/ηV, where IV is the luminous intensity in candelas and ηV is luminous efficacy in lumens/watt. 3. T-13/4. 4.

The transient peak current is the maximum non-recurring peak current the devices can withstand without damaging the LED die and wire bonds. It is not recommended that the device be operated at peak currents beyond the Absolute Maximum Peak Forward Current. Figure 1. Relative Intensity vs. Wavelength. Figure 2.
