They are matching the Sola line of 5600K fresnels with a new Tungsten only line called Inca.
They are very lightweight, and this is only my opinion, but I thought the use of plastic for construction of the Solas was a bit excessive. They didn’t look like they would stand up to rattling around a lighting kit very well. I might be wrong. From the picture above, they seem to be using a different yoke on the Incas, so maybe they’ve made some changes?
