1. Dominant wavelength is derived from the CIE 1931 Chromaticity diagram and represents the perceived color. Lumileds
2. Royal Blue product is binned by radiometric power and peak wavelength rather than photometric lumens and dominant
3. CRI (Color Rendering Index) for White product types is 70. CRI for Warm White product type is 90 with typical R
4. Spectral width at ½ of the peak intensity.
5. Total angle at which 90% of total luminous flux is captured.
6. θ½ is the off axis angle from lamp centerline where the luminous intensity is ½ of the peak value.
7. Cumulative flux percent within ± 45° from optical axis.
8. Off axis angle from lamp centerline where the luminous intensity reaches the peak value.
9. All white, green, cyan, blue and royal blue products built with Indium Gallium Nitride (InGaN).
10.Blue and Royal Blue power light sources represented here are IEC825 Class 2 for eye safety.
maintains a tolerance of ± 0.5nm for dominant wavelength measurements.
