Employing the widely-compatible Bowens S-Type mount, the glass Fresnel Lens for Forza 300 and 500 from NanLite modifies the Forza's wide beam spread to a focusable spot (10°) to flood (45°) coverage. The lens includes metal 8-way barndoors to further control the light beam. The Fresnel is compatible with the Nanlite Forza 720, 720B, 500 II, 300 II, 300B II, and the FS-series spotlights. It's also compatible with the first-generation Forza 500, 300, 300B, and 200.
