Also according to Sanjay, the Iwasaki 175W 15K bulb runs 87 and 71 PPFD on electronic and magnetic ballasts, respectively.

Thanks. I've never seen those 150 ones before. The 87 for the Iwasaki on electronics,s is the number I was refering to, in comparison to 250,s. Only a couple of the 250,s are better.
