All of the modifiers we sell will fit on the Ultra models of flash units. I would expect anything else to fit on the Flashpoint, if the 5.5" reflector also does. However, not being familiar with the Flashpoint model, I hesitate to guarantee anything, just in case something is just different enough. If it has the four retaining fingers (or three like Balcar), then you should be fine.
Thanks, with :D quick responses such as this, I definitely plan on acquiring a couple of your new strobes - most likely the Alien Bees.
Thanks again!
