I belive they use the older sensor. that being said most PAR meters underestimate any light source that is predominantly blue.

I believe I read some place that Neptune uses an Apogee 210.
If you look at the chart, the 210 is considered an original, so use that graph line.
I have the new SQ-520. It reads the blue spectrum better.

BRS did some testing.
