Anything over 60,000 and I start to get issues with foxtailing. I try to keep a minimum of 32,000 in my dark spots, but anything down to around 26,000 is good.
26,000= 600par
35,000= 800par under the HPS. Those aren't exactly right, but close enough on the numbers.

Please let us know how she responds. 15k lux is common, but I wonder if changing from 500 to 15,000 lux all at once might be to abrupt?

35k lux is more like 425 ppfd when comparing HPS fixtures.

If you'd watched the video I linked, you would have seen that Shane from Migro tests that exact meter against an Apogee PAR meter and gives graph values for different types of lighting towards the end of the video.35k lux is more like 425 ppfd when comparing HPS fixtures.

Which is why I use the same meter. It's effectively been "calibrated" for me so long as I follow the testing results.
I am mistaken though, according to the Apogee par comparison you only need to see around 22,000 on the meter to get 600 par...

So your assertion is that Apogee is wrong, but Migro is right? I dunno man, that seems like quite a stretch to me, unless you're saying that the lux meter in question is complete inaccurate. I dunno where you're coming up with that 22,000 lux = 600 par number either. The Apogee site doesn't support that claim at all.
