We just hung a 6 tube x 48" T8 high bay surface mount industrial light fixture in Suzy's painting studio for general illumination with Phillips 5000K 90CRI tubes. That thing puts out an astounding amount of light for just $80 plus the tubes. Simple sheet metal housing would be easy to adapt for stand rigging. Don't know how the ballast is for flicker, but that could be changed if needed. Haven't stuck a meter under it yet but an educated guess would be in the 40fc range average over most of a 750 square foot room from 10 foot ceiling.
