Distribution Graph

Angle: 132° (±66° from bottom), Maximum lux:

Graph notes: Shows the intensity of the light when viewed from different angles. Normal omni-directional globes have a fairly constant output all the way around (excepting directly above). Downlights have a narrow range at the bottom in which the light is emmited, this determines their angle.


Spectrum Graph

Representation of color spectrum

Graph notes: Shows the breakdown of the LED light into its component colors. With short wavelength ultraviolet on the left and long wavelength infrared on the right. The green line represents the relative absolute strength of the light at each frequency, while the red line represents what the typical human eye would see. The human eye is most sensitive to green light, but much less sensitive to purples and deep reds.
