So here is our new LEDko fixture. It is on the left, with a traditional Source4 of the same beam angle on the right. The camera auto adjusted the color temp to the LED (which shows you how much "whiter" the LED unit is).
The dimming curve on a scale of 1-10 is about an 8 (and I am very picky). It works well at any timing, I can't make it choppy if I try. It almost exactly mimics an incandescent curve until you hit about 1.5%-2%.
We are sending it out on a demo tomorrow, I will try and get the person demoing to post here after they look at it.
Here is the photo. We haven't put a photometer on it, but to the naked eye, it is brighter and the field is more even.
Of course, you do have to contend with a completely different color spectrum (with spikes in strange places) so you have to adjust how you look at gel, but overall we are very, very happy with how the unit looks/handles/works.
