I've reconciled myself to spending considerable amounts of money on this hobby but spending it twice because I made a bad call the first time annoys me. I was wondering if maybe there was something like a problem with my ballast that was giving me such a yellow output so I went and did some research to find out what would be a good comparison. I pulled a spectral plot off of Sanjay Joshi's site so I could get a rough idea what the Ushio 10000k should look like compared to a Hamilton SE 10000k I happen to have around. Turns out that the CCT he measured for the Ushio bulb was more like 6500k and if I compare it against some 6500k CFs I have it's pretty much the same. Great.

I'll admit to not knowing much about MH systems but this came as a bit of a surprise, from looking at Sanjay's site nobody is really offering a true 10000k bulb but at least most of them get closer than Ushio.
