Rapid LED Cree RB differences?

I was always under the impression that the RB XT-E were run at 1050mA? Maybe you over drove them?

As far as the lights not turning off, you should be running a timer or power controlled module to kill power to the drivers when they are run down to 0v on the 1-10V circuit. Some drivers tend to continue to supply some current even at 0v (I had one do this).
