Dude...that's killer. That Mal x Pan is no joke. I took mine down as well and it proved very chunky (One of them, the other didn't seem to want to finish no matter what I did.) We're trying to save it and get a really good run with her again.
Fantastic numbers, my dude. Keep it up!
What I'm dealing with in regards to the 315's is that you bear a bit of cost down the road for bulbs. You could start to lose par in dramatic fashion after 6-8 months of daily use. We've had a whole room cut it's par in half since last August; they didn't even make it a year and it's slowing everything down. Probably easier for you if you only have to swap a bulb at a time but in my case it becomes thousands and thousands of dollars. Otherwise the 315's are pretty spectacular. I'd run em in my tent again for sure but the bulb I've got has maybe only one good run left in it.
