An ETC Source Four Lens Tube – 26º is a medium‑wide beam lens designed to provide smooth, even coverage at moderate throw distances. The 26º beam angle makes it a versatile choice for front light, area lighting, and general stage coverage. This lens tube delivers a clean beam with sharp shutter cuts, allowing designers to shape light accurately while covering a larger area than narrower lenses. This lens tube installs directly into compatible Source Four ellipsoidal fixtures and is commonly used in theaters, houses of worship, and other venues.
