With more than 10 years of experience including 7 years of analysis and feedback on the Source Four Series 2 Lustr, ETC has developed the 3rd generation of Source Four. Equipped with the Lustr X8 Led panel, it produces deep reds and features a new range of XDLT optical “noses”, optimized for LED sources. We put it through the bench tests at La BS and compared it to the Series 2 Lustr and the original Source Four version with the halogen lamp.
