The Vivitar VI was an interesting enlarger concept in the late 70s. Our community darkroom has a unused one stored on the floor. It's manual says, "The dioptic light source is a high intensity, cool and integrated light system, designed specifically to convert the Vivitar VI into a universal, color and B&W enlarger. It features the exclusive "Light Pipe" which functions both as a color integrator and a cool light transmitter with over 90% efficiency. It provides a full range of 0-200 color correction units with permanent dichroic filters, allowing simulation of all popular variable contrast, B&W paper grades. Its immediate advantages are reduced exposure times, uniform condenser illumination and virtual elimination of heat at the negative plane.
