14° XDLT lens tube for Lustr3

This high-performance lens tube replaces the original optical barrel on ETC Source Four LED Series 3 Lustr fixtures. Engineered for projection clarity and brightness, it’s built to deliver standout performance on large stages, theaters, film sets, and venues—especially when long throw distance and crisp imagery matter.
