Confirm the exact configuration against the current manufacturer specification sheet before approval or purchase.

Engineering reference

## Selecting within the FYS / FYD family.

Output decides the body: below 80 W the FYS housing is sufficient, above 100 W the FYD is required. Confirm the physical envelope, since the two differ in both diameter and depth, and confirm the voltage band.

FYS and FYD are one platform in two body sizes: FYS at φ308 mm covers 20 to 80 W, FYD at φ358 mm covers 100 to 200 W. Keeping them on one page reflects how they are specified — a facility standardises on the platform and picks the body by output.

Common questions

## Useful answers before the next step.

These answers clarify the selection process without replacing project-specific documentation.

**What is the difference between FYS and FYD?**

Housing size and output range. FYS is φ308 × 166 mm covering 20 to 80 W at 3,000 to 12,000 lumens; FYD is φ358 × 157.4 mm covering 100 to 200 W at 15,000 to 30,000 lumens.

**What classification is documented?**

Class I Division 2 Groups A to D, Class II Division 2 Groups F and G, and Class III, with IP66 and IK10. Confirm against the specific catalog number.
