Optimize Your Wall Pack Light Distribution The CSC LED Type IV Optics accessory (KWP-TYPE-IV-SM) is engineered specifically for the 40W Keystone Wall Pack series, allowing you to take full control of how light is projected across your space. Whether you're illuminating a building facade, a parking lot perimeter, or a commercial driveway, the right optic makes all the difference between wasted light and effective, targeted coverage. What Is Type IV Distribution? Type IV is a forward-throw, asymmetric light distribution pattern recognized by the IES (Illuminating Engineering Society). It projects light predominantly in one direction — ideal for mounting on walls or poles at the edge of a space. This means maximum illumination where it matters most, with minimal light trespass onto neighbouring properties or into the sky. It's the go-to choice for perimeter lighting, parking areas, walkways, and building exteriors. A Smart, Cost-Effective Upgrade Instead of replacing your entire wall pack fixture, simply swap in the Type IV optic to adapt your existing 40W CSC LED Keystone unit to a new application. This modular approach saves time, reduces waste, and keeps your project costs low — a practical solution for contractors, facility managers, and lighting designers across Canada. Available at Lumibox.ca for only , this small investment delivers a significant impact on your lighting performance. Compatible with CSC LED's Keystone Wall Pack platform.
