All LEDs on, at minimum brightness.

Reverse-engineering the LED models: 'Orange-Red', 617nm, half-width 20nm. 'Lime', 567.5nm, half-width 100nm. 'Royal Blue', 447.5nm, half-width 20nm.

CIE xy parameters for gamut bounds, per philips' dev center: red = [0.675, 0.322] green = [0.409, 0.518] blue = [0.167, 0.040]

centroid: [0.417, 0.2933].

I set the light to the centroid of the gamut and captured the spectrum. -- (Cloned calibration from Fluorescent tube) -- (Cloned calibration from 6500K CFL) -- (Cloned calibration from 6500K CFL)

Operation Date Description

Operations enable reversible modification of data -- they act like filters which process the data. The graph you see above represents the data after these operations have been run. Delete them to undo their effects, or to apply them in a new order.

  • The thumbtack symbol indicates that data has been saved in a snapshot upon running that operation.
  • The symbol indicates that the operation's data snapshot is being referred to by another operation. Click it to learn more.
  • Operations with a #000-style suffix, like subtract:3243#2414 are referring to a specific snapshot (in this example, #2414) of another spectrum. Click to learn more.
