Description
The SIRUI P1836A 18°–36° Stepless Zoom Projector Lens is a precision lighting accessory designed to give photographers and filmmakers creative control over beam angle, focus, and light shaping—all in one compact, Bowens-mount-compatible unit.
This projector lens attaches to COB lights (recommended for use with lights under 200W) and allows you to adjust the beam angle from 18° to 36° without swapping lenses. With a simple twist of the zoom ring, you can fine-tune the light’s spread and focus, making it ideal for spotlighting, shaping shadows, and projecting patterns using included GOBOs and shutter blades.
