The ETC Source Four EDLT 50 Degree Leko upgrades a standard Source Four ellipsoidal with an enhanced definition 50 degree lens tube to deliver crisper, higher-contrast projections and up to 10% greater light output. Designed for rental use, the unit preserves familiar Source Four operation while improving image sharpness for gobos, logos, and other detailed projections.

• Rugged die-cast aluminum construction suited to repeated rental use.
