Thanks I forgot that. I plan on running 10K Ushios which are universal burn position.Awesome fixture, but keep in mind that not all MH bulbs are designed to operate in the vertical "Base Up" position.
Example - The Radium 20K can only be operated +-55 deg from horizontal per the datasheet and package label.

I also have another 2 fixtures I can run Radiums on if I decide not to run this one.
