The ETC Source Four JR 26 is an efficient and versatile ellipsoidal reflector spotlight designed for theatrical, studio, and architectural lighting applications where space, budget, and power consumption are key considerations. As a member of the renowned Source Four JR series, it offers a more compact and lightweight alternative to the full-size Source Four while maintaining the core optical principles that have made the line an industry standard. The fixture produces a sharp, well-defined beam with exceptional field flatness and color consistency, thanks to its patented, faceted ellipsoidal reflector and optimized optical train. The "26" designation refers to its 26-degree field angle, providing a medium-narrow beam ideal for key lighting, specials, and highlighting specific areas on stage or in a display environment.

Constructed with a durable, die-cast aluminum housing, the Source Four JR 26 is built to withstand the rigors of repeated use in touring, rental, and permanent installation contexts. Its efficient design is highlighted by the use of a 375-watt tungsten-halogen lamp (or compatible LED retrofit engines), which, when combined with the precision optics, delivers a high output that rivals that of many conventional 500W or 750W fixtures. This results in significant energy savings and reduced heat load, a critical factor in smaller performance spaces or temperature-sensitive installations. The fixture includes standard features such as four framing shutters for beam shaping, a slot for a C-size color frame, and a gel frame retainer, providing essential tools for creative control. The lens tube is easily rotatable, allowing the shutters to be oriented as needed, and the entire optical assembly can be focused smoothly via a large, accessible knob.

The fixture's compatibility with the extensive family of ETC Source Four accessories, including interchangeable lens tubes, patterns (gobos), and color scrollers, greatly expands its utility. While it ships as a standard tungsten-halogen unit, its design accommodates official ETC LED retrofit kits, allowing for a straightforward upgrade to a silent, durable, and even more energy-efficient light source without replacing the fixture body. The ETC Source Four JR 26 represents a thoughtful balance of performance, size, and efficiency, making it a preferred choice for educational theaters, churches, television studios, and any application requiring reliable, high-quality ellipsoidal lighting in a more compact and economical package.
