## Long description

EUROLITE PST-40 QCL Spot 20° diffuser disc for 20° spot fixtures is an accessory created to modify the beam characteristics of compatible QCL spot heads. Designed to fit the PST-40 series spot head, the diffuser disc gently softens the 20° beam to reduce hard edges and create smoother light transitions on stage, in studio setups or architectural installations.
Advantages
The diffuser disc provides controlled diffusion without significantly altering beam direction, preserving the original 20° coverage while softening contours. It is lightweight and easy to mount on the PST-40 series spot head, enabling quick adaptation during rigging or rehearsals. The optical material is selected to maintain consistent colour rendering and to minimize hotspots, improving blend between multiple fixtures and offering a more even wash across surfaces.
Suitable for
 Live concerts and touring productions where softened spot edges are required
 Theatre and stage performances to achieve smoother light transitions
 Photography and video shoots that need reduced beam harshness
 Architectural and exhibition lighting for more even illumination
Key specifications
 Compatible with PST-40 series QCL spot heads designed for 20° beam angle
 Optical diffuser element engineered for softening 20° beams
 Low weight for minimal impact on fixture balance and rigging
 Retains original beam direction while reducing edge contrast
 Durable material suitable for repeated installation and removal
How to use
Attach the diffuser disc to the front of a compatible PST-40 series QCL spot head according to the fixture's accessory mounting procedure. Ensure the disc is seated securely before powering the fixture. Use with the fixture focused and positioned as required; minor adjustments to focus or aiming may be necessary to achieve the desired softened effect. Remove the disc when a sharp 20° spot is required or when changing beam shaping accessories.
Usage recommendations
For best results, pair the diffuser disc with fixtures of the same type and colour calibration to maintain consistent light blending. Check fixture mounting and balance after installation and avoid exposing the disc to high temperatures beyond typical fixture operating conditions.
