Totally Usable
Another thing I found in my travels was the Visionsmith booth. They had a cool product they called the "ReLamp." Basically it replaces your halogen fresnels with LED bulbs. The bulbs are 98 CRI, and they work with the existing dimmers. They're flicker free, and fit 300w, 650w, 1K, and 2K fixtures. I hadn't heard of these guys, but they've got a cool thing going.
