I also found some more information on the GE site that explains the SPX 50's different color.

The SPX comes in two different colors: a red-enhanced SP30 or SPX30 for flowering and fruiting plants; or blue-enhanced SP50 or SPX50 for vegetative plants. The SP and SPX are plant grow-lights, so although they are rated as daylight bulbs, their color is not as important as the amount of energy for photosynthesis and other plant photoresponses they provide.

So I guess the GE Chroma 50 or Chroma 75s are the bulbs you want for studio lighting - not the SP or SPX bulbs. I hope this clears up the mistake I made in my first post.
