Notes:
1.Slots in aluminum core PCB for M3 or #4 mounting screw.
2.Electrical interconnection pads labeled on the aluminum core PCB with "+" and " " to denote positive and negative, respectively.
All positive pads are interconnected, as are all negative pads, allowing for flexibility in array interconnection.
3.Electrical insulation between neighboring Stars is required —aluminum board is not electrically neutral.
4.Drawings not to scale.
5.All dimensions are in millimeters.

Notes for Tables 1 & 2:
1.Minimum luminous flux or radiometric power performance guaranteed within published operating conditions. Lumileds main
tains a tolerance of ± 10% on flux and power measurements.
2.LUXEON types with even higher luminous flux levels will become available in the future. Please consult your Lumileds
Authorized Distributor or Lumileds sales representative for more information.
3.Typical flux value for 470 nm devices. Due to the CIE eye response curve in the short blue wavelength range, the minimum
luminous flux will vary over the Lumileds blue color range. Luminous flux will vary from a typical of 17 lm for the 460 465nm
bin to a typical of 30 lm for the 475 480 nm bin due to this effect. Although the luminous power efficiency is lower in the short
blue wavelength range, radiometric power efficiency increases as wavelength decreases. For more information, consult the
LUXEON Design Guide, available upon request.
4.Royal Blue product is binned by radiometric power and peak wavelength rather than photometric lumens and dominant
wavelength.

Notes: (for Tables 4 & 5)
1. Dominant wavelength is derived from the CIE 1931 Chromaticity diagram and represents the perceived color. Lumileds
maintains a tolerance of ± 0.5nm for dominant wavelength measurements.
2. Royal Blue product is binned by radiometric power and peak wavelength rather than photometric lumens and dominant
wavelength. Lumileds maintains a tolerance of
± 2nm for peak wavelength measurements.
3. CRI (Color Rendering Index) for White product types is 70. CRI for Warm White product type is 90 with typical Rg value of
70. CCT ±5% tester tolerance.
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). All red, red orange and abmer
products built with Aluminum Indium Gallium Phosphide (AlInGaP).
10. Blue and Royal Blue power light sources represented here are IEC825 Class 2 for eye safety.
