An ETC Source Four PAR Wide Lens is an interchangeable lens designed to give a Source Four PAR fixture a broader beam spread for area lighting and general stage washes. Compared to narrower lens options, the wide lens covers more surface area with a softer, more dispersed field of light, making it useful for illuminating scenery, backdrops, stage decks, and audience areas. Because Source Four PAR fixtures use interchangeable lenses, the Wide Lens provides a quick way to adapt a fixture to different lighting needs without changing the fixture itself.
