Barrel 19° for Source Four/Leko
When your lighting situation requires even more precise optics for spot lighting or projecting images, gobos, and logos, a Lens Tube or "Barrel" is an invaluable addition to your Source Four package. The barrel attaches easily to any Source Four ellipsoidal spotlight. While increasing light output up to 10%, barrels also provide heightened sharpness and stunning contrast to images when the Source Four is used as a pattern projector.
The 19 degree provides a narrow spread of light when installed in any ETC spotlight.
