Nice, we use a Floodlight as a blinder like these:

We just mounted them to our truss and hooked them up to a 3-socket dimmer pack.
Oh and i just found out that when we use these bulbs with freestyler (we are just now only switching to a computer-controlled system) they actually work

, with our previous setup, they were slow to turn on and they occasionally got stuck on, and you had to turn them off completely just to unstick them!
