Comparing PAR readings

[fkshiu]

I can't do a new bulb/old ballast comparo because I'm going from 250W to 175W ballasts.

The pictures aren't an accurate representation of what the tank looks like. I just put the Radium readings on an old picture when I was using XM 10K bulbs, in fact. Here is what the tank looked like with the Radiums and all my actinics on (VHO URI superactinic and T5HO G-man Actinic+) - yes, it was go blue or go home:



The picture with the Iwasaki readings is what the tank looks like now with the Iwasakis along with various actinics. However, I took all the PAR readings with only the MHs on.
