IsAKelvin

• 1 : Is a Kelvin
• 0 : Not a Kelvin

If it is "Not a Kelvin" then the color of the light does not fit to the Kelvin line on the CIE colourspace

Kelvin

Integer; Actual numeric value of the colour temperature in Kelvin. Shows as 0 if the colour if "IsAKelvin" is 0

X & Y

Integers divided by 10000 to plot the X&Y position of the colour on the CIE colourspace that shows the approximate colour of the light. This is limited to colours that are are near an actual Kelvin.

PAR

Direct integer value of the PAR output

LUX

Direct integer value of the LUX output

PUR

Direct percentage value of the PUR
