It's interesting, but their day white chips are only 100 lumen each, and
the warm white ones only half that. And they appear only to fabricate
them into strips of six chips. I think there's still some way to go
before we get any 300 X 300 mm ceiling panels producing 2000 - 3000
lumens.

Is the "addition" of lumens linear or log? Would an array of 60 chips
@ 50 lm give you 3000 lm total? 60 chips is only an 8 x 8 matrix. 30
mm pitch will fit in a 300 mm square no problem...
