New here confused at ppfd map

Hello all
Currently running a 300w attis
Was considering upgrading to zeus 465w pro
But when I download ppfd map from lumatek website the attiss shits all over the 465w pro
Is it a mistake?

Not sure what your looking at. The numbers on their site for both fixtures seem to make sense. They have similar numbers for the center but the atts drops off like crazy in the corners where the Zeus doesn’t.

The 465w map is 1.2 i know but love to know if any one else had done same upgrade
And noticed a vast difference
