need some help with black lighting an event

Doing a 'glow party' in a couple months. probably about 700 people. I'll have two 30 foot trusses on either side of the room. They're also having a dj present. From a design perspective i'd like to be able to achieve moving black light. I have a bunch of Studio Spot 250's that actually have a UV in the color wheel and works nicely, but was thinking of getting something else to really punch. Perhaps Studio Commands or Beams? Can they achieve a UV or similiar effect? Any experience?
