Color Blaze/RGB led strobe

Wondering if anyone else has noticed or come up with a solution to an issue I consistently get with my Color Blazes (patched as generic RGB). Basically, if I try to strobe them using a sped up step effect they seem to sine the base value of the intensity. In other words while strobing they seem to cycle between 0% > full intensity and 50% (ish) > full intensity so I can never get a consistent on/off strobe effect. Am I making sense?
