Minimum luminous flux performance
guaranteed within published
operating conditions.
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.
Minimum 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 range from minimums of 35
lm for 12-Up and 50 lm for 18-Up
Floods at 460nm to typicals of 190
lm for 12-Up and 280 lm for 18-Up
Floods at 480nm 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.

Dominant wavelength is derived from
the CIE 1931 Chromaticity diagram
and represents the perceived color.
CRI (Color Rendering Index) for White
product types is 70.
Spectral width at �½ of the peak
intensity.
�
is the off axis angle from lamp
centerline where the luminous intensity
is �½ of the peak value.
Luxeon Floods are not designed for
direct view applications. Lumileds
reserves the right to mix LEDs of
different color and flux values to
achieve the typical values listed above,
possibly resulting in visible variation
across the array.
All red and amber products built with
Aluminum Indium Gallium Phosphide
(AlInGaP).
All white, green, cyan, and blue
products built with Indium Gallium
Nitride (InGaN).
All power light sources represented
here are IEC825 Class 2 for eye
safety.
