ETC Source Four Mini LED 50 Degree
12W LED Mini Ellipsoidal with 50 Degree Lens, Portable


ETC offers the 4M50L - a Source Four Mini LED that is a portable, 50° field angle fixture that comes in black. This 12W Source Four Mini LED features the same crisp optics, user-friendly functionality and sleek look of the legendary Source Four fixture, but in a compact format at a fraction of the size.

The Source Four Mini™ is everything you expect from the Source Four® brand – ease of use, superior optics, crystal-clear image projection and a bright, even field – but packaged in a tiny fixture that’s just one-third the size of a traditional Source Four. A mere nine inches long the Source Four Mini can go anywhere: museums, retail outlets, restaurants, light labs, children’s theaters, and other small scale installations where size matters.

The Source Four Mini is available in four field angles: 19°, 26°, 36° and 50°, with a 2.5" diameter lens. It comes in a portable version with a miniature C-clamp, a canopy-mount design with an integral transformer, or a track-mount design. There is also a low-voltage (12V) tungsten version. All Source Four Mini models include an E-sized pattern holder and a gel media frame, with a range of additional accessories.
