And provided that they happen to have backlight LEDs from the same batch
that you tested.
To save cost, we don't spec the LED color tightly - rather we specify
that all of the LEDs that go into an individual LED bar must be matched
to each other. There can be substantial unit to unit color variations
in the "white" of the backlight.
Apparently this increases the LED manufacturing yield, dropping the
price significantly.
