figures are under /sys/class/i2c-adapter/i2c-2/2-0029 folder.
light metter have 2 sensors :
infrared & visible >> channel 0 .......adc0
IR only >> channel 1..............adc1 (also founded in sysfs folder )
in plain sunlight i expect ir sensor ( 1 ) have high values so a simple script can turn off lcd backlight after this value is above a custom set value .

sysfs lux value is a computed value based on arbitrary formula.
