I think someone should develop a retrofit LED that modifies the dimming curve so that it has a smooth fade to black before the power is insufficient for to opperate the electronics. A profile on the control board or a curve in the dimmer could translate 1-100% control to 10-100% power and the fixture could translate 10-100% power to 1-100% light.From a poster on the "everything stage lighting" facebook.
"So the official release of the ETC 4wrd is tomorrow, but here's a sneak peek I got today at a CITT event.
155W power usage, dimmable down to ~5% or direct DMX control which turns off dim-ability. (Electronics need a minimum voltage to operate hence the minimum dimming level)

It will be interesting to hear shootout comparisions of a Source 4 with 4WRD to a Chavet Ovation ED. So far it looks like the Source 4 with 4WRD will be less expensive even if you have to buy a Source 4 new to retrofit.
