Lumens Note 2
Watt
Notes:
1. The dominant wavelength, ld , 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 /hV , where IV is the luminous intensity in
candelas and hV is the luminous efficacy in lumens/watt.
