Optimize Your Wall Pack Light Distribution Get the most out of your CSC LED WPX Wall Pack with the official Type 4 Short (T4S) optic accessory . Designed specifically for the 30W and 50W WPX Wall Pack models, this replacement optic allows you to customize your light distribution pattern to suit your exact installation needs — without replacing the entire fixture. What Is a Type 4 Optic? Type 4 distribution is a wide, asymmetrical spread ideal for illuminating large vertical surfaces, building perimeters, parking areas, and pathways. It projects light outward from the wall, maximizing coverage along a wide horizontal plane — perfect for commercial, industrial, and institutional exterior lighting applications. Built for the WPX Wall Pack Series This optic is engineered as a drop-in accessory for CSC LED's WPX Wall Pack family. Whether you're upgrading an existing installation or configuring a new one, swapping optics allows you to tailor performance without extra hardware or wiring changes. Compatible with both the 30W and 50W WPX models . Why Buy at Lumibox?
