I used the Ushio 20K lamp in the PAR tests. The lamp (and ballast for that matter) was about a month old when I took the PAR readings. I also tested the current usa 14K 70w lamp that came with the sunpod fixture and the PAR was a bit lower only topping out at about 390PAR.
I never tested my 32w PC retrofit that I used on my mini bow 7. I should throw it back on there and see what the PAR is?
