It's... this one... hopefully the link works..
they were similar setups but done on different days. sometimes the par sensor is aligned slightly differently, the ambient temp is higher, etc. i try not to compare tests from different days, the results are relative to other cobs tested under same conditions, not absolute. the same trends are seen in repeated tests but the actual ppfd/W can vary on a different testing day. I'm trying to standardize this by only doing par measurements in the sphere from here on out.
