ETC Source Four LED CYC Lens Tube

By attaching a Source Four LED CYC adapter, any Source Four LED can become a superior tool for lighting cycloramas. With highly tuned optics, the Source Four LED CYC adapter provides incredibly smooth, evenly-distributed coverage, without visible gaps. Backed by the x7 Color System™, the CYC adds a nearly limitless array of bold colors to cycloramas, and can be fine-tuned to accentuate or subdue individual hues in painted backdrops. 

You don't need a PhD in lenses to know how to use it. Instead of struggling with a complicated lensing formula that can take hours to get right, the Source Four LED CYC requires no additional lenses or diffusion. It simply connects to any Source Four LED light engine and is ready to go, reducing setup time and hassle.
