EUROLITE 40° Diffuser for IP PAR-3 (Model 51914244) – 40° Beam Angle

The EUROLITE 40° Diffuser Disc for IP PAR-3 is an interchangeable optical accessory designed to modify the light output of compatible IP PAR-3 fixtures to a 40° beam angle. It produces a wider, softer beam with smoother edges compared to a narrow spot, enabling more even illumination across surfaces and reduced hot spots. The disc is engineered for straightforward installation and reliable fit with the intended fixture, preserving the IP PAR-3’s weather-resistant properties while changing beam distribution.

Advantages

This diffuser disc provides consistent beam shaping to achieve a true 40° spread, improving coverage for mid-range wash and soft-front lighting needs. By softening the beam edge it reduces contrast between lit and unlit areas and helps create uniform color blending when used with RGB or color-mixing fixtures. The accessory is lightweight and easy to mount or remove, enabling fast adaptation of an existing IP PAR-3 rig without additional tools or major repositioning of fixtures.

How to use

Ensure the fixture is powered off and cooled before attempting installation. Align the diffuser disc with the front of the IP PAR-3 housing and engage it according to the fixture’s accessory mounting method until it seats securely. After installation, power the fixture and check beam spread and focus at the intended throw distance; adjust fixture aim or mounting position as needed to obtain the desired wash. To remove or replace the disc, power down the fixture and reverse the installation steps.

Recommendations

For best results, test the diffuser disc at the distance and angle representative of final use to confirm the 40° coverage meets scene requirements. When combining multiple fixtures, allow for slight overlap to avoid visible seams and ensure consistent color balance when using color-mixing modes. Store the disc in a protective pouch when not in use to avoid scratches or dust that could affect beam uniformity.
