The ETC Source Four 25–50° Zoom is a flexible, professional-grade profile spotlight designed for theater, corporate, and event lighting. With a variable beam spread from 25° to 50°, it delivers precise control, smooth field adjustment, and sharp focus.

Equipped with a 575W HPL 120V+ lamp, this Source Four produces up to 16,000 lumens of warm, even tungsten light. The rotating barrel, four independent shutters, and smooth zoom mechanism make it easy to frame or texture light exactly where you need it.

This rental includes the complete fixture, lamp, mounting yoke, C-clamp, and safety cable.

Note: This fixture can also be configured for HID operation using a 150W Philips MasterColor CDM-T 4200K lamp.
