The Mainframe is the heart of the LiteMod system, providing the interface for accessories, including the Snoot, the Barndoors, the Gels/Filters, the Gel Holder, and the Honeycomb Grids. It easily attaches to your X-Series, UltraZAP, Ultra or ZAP series unit in place of the reflector. The Mainframe design offers a sturdy fit, reduces light spill, and provides heat dissipation with its air-flow holes. With the built-in reflector/mainframe design, you can position your flash unit in any configuration, and securely fasten accessories to achieve various effects.
