The ETC Source Four Zoom 25-50 degree is a compact, rackable ellipsoidal fixture offering a continuously variable field angle from 25 to 50 degrees. It provides a bright, even field with a cool beam, and is designed for quick on-site adjustments and safe operation.

Key Features

• 25–50° zoom range, allowing one fixture to cover multiple field angles.
• One-handed zoom operation for fast, single-technician adjustments.
• Faceted dichroic reflector that removes approximately 90% of IR heat from the beam, keeping shutters and accessories cool.
• Rated up to 750 W and uses a super-efficient HPL lamp for consistent output.
• Rotating barrel and three-plane stainless-steel shutter assembly for precise beam shaping.
• Positive zoom lock, field angle and focus scale markings, and insulated rear handle for safe handling.
• Supports dimmer doubling for flexible power use in rental rigs.

Use Cases

• General theatrical and concert lighting where variable beam angles reduce fixture count.
• Corporate events and broadcast where a cool, even field is required to protect set pieces and talent.
• Rental productions that need fast focusing and durable accessories compatible with fixed-focus Source Fours.
