SeaChanger Tungsten products are dynamic CYMxG color changers used with your ETC Source Four® Ellipsoidals. They utilize dichroic filter technology, creating a nearly endless palette of stable, reproducible colors that don’t shift or fade with time. The SeaChanger™ Tungsten Profile accommodates beam-shaping ETC Source Four® accessories including any FOV barrel (5°, 10°, 14°, 19°, 26°, 36°, 50°, 70° and 90°), Enhanced Definition Lens Tubes (EDLT), Source Four® Zooms and gobos.

Quiet, swipe-free color transitions in less than a half a second are easily accomplished using DMX or RDM control. The xG filter extends the CYM color gamut, and creates deep blues, rich reds and vibrant greens; the xG filter adds natural overtones and nuance to the standard CYM palette, creating a new dimension in realistic scenery lighting.
