The ADJ Lens Tube 19D is a precision optical accessory designed specifically for the Encore Profile Pro series of LED ellipsoidal spotlights. This interchangeable lens tube defines the fixture's field angle, with the "19D" model providing a 19-degree beam spread. Installing this tube shapes the output into a defined, hard-edged beam ideal for projecting sharp patterns (gobos), isolating subjects on stage, or creating precise areas of light with minimal spill, which is essential for theatrical and architectural lighting.

The tube is constructed with a multi-element glass lens system housed in a durable metal barrel, ensuring optimal light transmission and clarity. It is engineered to seamlessly integrate with the Encore Profile Pro fixture via a secure locking mechanism, allowing lighting technicians to quickly change the beam angle on-site to suit different requirements of a production. This interchangeability greatly enhances the versatility of the base fixture, enabling a single spotlight to serve multiple functions throughout an event or show.

This professional accessory is a key component for lighting designers who require control and flexibility from their ellipsoidal fixtures. By allowing quick field changes of the beam angle, the Lens Tube 19D helps optimize the lighting rig for different scenes or venues without needing multiple dedicated fixtures, making it a cost-effective and practical tool for theater, houses of worship, and live event production.
