I recently obtained a Apogee SQ222 PAR sensor from a fellow hobbyist. This PAR meter is limited in that anything above 200 registers the number "1", which limits some PAR readings.
In my case, my Chihiros Series A Plus are high enough that at the highest setting i'm able to get good readings (setting 1-7). For reference, tmiravent & Nuno conducted a more comprehensive test on the Chihiros Series A and a variety of other lights so please reference that data set.

I'm running the Series A Plus on a 17.7L x 10.6W x 11.8H; the lights sit the extended legs provided so they are 22.3cm high. In total, these lights are ~23.5cm above the surface of the water. Measurements are taken `1.27cm below the water surface:
PAR @ substrate:
For reference, these light are pushing out about 50 additional PAR relative to the Series A at a higher distance based on the analysis conducted by tmiravent & Nuno.
I'm running my lights on setting 4, so 115 PAR at the surface and 55 at the substrate.
I have the unit for a few additional days so am willing to do additional testing if any interest arises with the caveat that > 200 I won't be able to get a reading.
