The ETC Source Four Mini is a compact ellipsoidal spotlight that delivers the optical precision of the full-sized Source Four in a scaled-down format ideal for architectural and small-scale theatrical applications. Equipped with a 50-watt tungsten halogen lamp, this version features a fixed 50° beam angle and a 2.5" lens diameter, offering a bright, even field with crisp image projection. The fixture includes a three-plane shutter assembly for beam shaping, an E-size gobo holder, and a gel media frame. Designed for flexibility, its rugged die-cast aluminum housing and tool-free adjustment features make it suitable for museums, retail spaces, and educational environments where space is limited but lighting quality is essential.
