Reply to Epilepsy safe lights

So I'm going to be DJing a church dance, and apparently some of the people there might have epilepsy. I'm not too in the know with what actually triggers epilepsy besides strobes, so I was hoping someone in the know might be able to tell me which/any of these lights that I have runs the risk of triggering it?

Chauvet Derby X
Disco Ball (Might as well include a complete list)
Chauvet MiN RGX 2.0 Laser
American DJ Roto Balls

Thanks!
