Wow, that is so cool, and I really like the idea of being able to retrofit this to a non-fx Roman (of which I have a kit on the way). Depending on the price I may be down for one of these :cool. I also agree with Chaim; the pulse should be faster. Either that, or it shouldn't fade all the way off. I think it would cool if the light slowly fluctuated between 2 different intensities instead of fading all the way off.
